DX Engineering 80 Meter Self Supporting Heavy Duty Vertical Antennas, model DXE-7580FS-VA-2, are high performance vertical antennas specifically designed for the 75/80 meter band. These DX Engineering 68 ft. vertical antennas allow you to achieve the strongest possible presence at your power level and be competitive. These are FULL SIZE, quarter-wave vertical antennas that deliver fantastic specs and the highest possible performance at a price that can easily be justified.

Every design detail of the DXE-7580FS-VA-2 Heavy Duty Verticals provide for a very rugged 80 meter antenna that can stay up with no guying necessary and no worry. A 3 in. O.D. thick-wall 6061 aluminum tubing base and an extra-large insulating channel are combined with a patented* heavy duty stainless steel pivoting fixture that is second to none. Engineered for ease of assembly and adjustments, with corrosion-resistant aluminum tubing, stainless steel mounting brackets, and stainless steel hardware, these are very durable and attractive self-supporting antennas. If an extreme wind storm is predicted, one operator can easily lower and raise these antennas safely, due to the simplicity of the included Heavy Duty Pivoting Fixture and optional DXE-VRW-1 Manual Winch.

DX Engineering 80 Meter Self Supporting Heavy Duty Vertical Antennas offer full band coverage, with a 2:1 SWR bandwidth of up to 557 kHz, depending on your radial field. Your internal tuner can get the SWR down to 1:1 on any DX frequency for maximum power transfer.

DX Engineering 80 Meter Full Size Quarter Wave Heavy Duty Vertical Antennas feature:
— Self-supporting – will withstand steady-state winds in excess of 92 MPH without guying (guying required under extreme wind speed conditions)
— 5 kW SSB and CW rated—unparalleled reliability
— Ultra-rugged construction starts with 3 in. O.D. aircraft-grade heavy wall tubing
— Ultra-wide SWR bandwidth and unbeaten gain
— Highest wind ratings–high strength 6063/6061 tubing manufactured to DX Engineering specifications
— Easy tilt up and down– Unique fold-over antenna mount features DX Engineering’s patented stainless steel Pivoting Fixture, *U.S. Patent Number 8,130,168
— High power handling and high strength, UV protected EXTREN® insulators
— No rust–100 percent stainless steel tubing clamps and hardware
— Reliability second to none–specially manufactured stainless and aluminum saddle clamps, stainless bolts, and precision machining on each antenna

Note: For additional information, please look at the files under the “Documentation” tab.

Designed to the highest of standards, DX Engineering 80 Meter Self Supporting Heavy Duty Vertical Antennas are very affordable, and could very well be the finest 80 meter antenna you will ever own.

Well-Known Contester, DXer Bob Morris, W4MYA, SK

Fri, 08/17/2018 - 11:30

Robert S. “Bob” Morris, W4MYA, of Goochland, Virginia, died on August 14. An ARRL Life Member, he was 72. Morris had been suffering from cancer but remained active on the air until very recently. He was sometimes called “Dude” within the contesting community for one of his favorite expressions, “Run ’em, dude.”

Morris was a member of the Potomac Valley Radio Club, enjoyed both contesting and DXing, and had built a multi-multi station in Goochland, where he mentored budding operators. In his working years, he was employed by AT&T in the Long Lines department. Fred Laun, K3ZO, remembered W4MYA as “the same go-hung fellow, right up to the end.” — Thanks to The Daily DX

Introducing the World’s longest 50MHz/70MHz Dual Bander?

Fri, 08/17/2018 - 07:14

The new 6-4-20 is a serious performer with an 11.1m computer optimised tapered boom and 10 elements on both 50MHz and 70MHz with a single feed point.

The 6-4-20 provides impressive performance on both bands with 14.46dBi free space gain on 70MHz and 13.41dBi free space gain on 50MHz. Placed 12m above average conductive ground, gain increases on 70MHz to over 20dBi and on 50MHz to almost 19dBi.

In addition, the 6-4-20 has been optimised for FT8 frequencies as well as the traditional operational areas of the band so as can be seen from the plots, SWR is flat through both bands os no amplifiers will have issues.

The previous longest dualbander for these bands was the 8-8-8- which has an 8m boom with 8 elements on each band sells well. The new dualbander has been in operation at OH5LK and EA5GF this summer with excellent results.

Dave Popkin, W2CC/AAR2BU Receives Presidential Lifetime Achievement Award

Wed, 08/15/2018 - 16:07

A New Jersey radio amateur and Military Auxiliary Radio System (MARS) member has received a Lifetime Achievement Award from President Donald Trump. ARRL Charter Life Member Dave Popkin, W2CC/AAR2BU, was recognized for his extraordinary contributions as a MARS volunteer.

“On behalf of a grateful nation, I thank you for your lifetime of service to your fellow Americans and those most in need,” President Trump said. “Through at least 4,000 hours of service, you have ensured the continuation of America’s unparalleled commitment to improving the lives of others. You have served as a model of the American spirit. Your many hours of service have strengthened the bonds of cooperation and trust that bring people together, while helping to address some of the greatest challenges of our time.”

MARS Region 2 Director Carver Washburn, W2TFM/AAA2RD, said Popkin’s “long and distinguished” history as a volunteer extends over 56 years with US Army MARS, averaging some 2,000 hours a year.

“Dave is particularly noted for his MARS leadership roles, mentoring, and training initiatives,” Washburn noted. “It all started with his inspiration and his motivation to take positive action that, to this day, has fundamentally enhanced the ability of [the Department of Defense] to achieve its goals under the most dire of circumstances, such as occurred in Puerto Rico during Hurricane Maria in September 2017.”

Washburn said Popkin served as net control for MARS radio nets in Region 2, and has served as MARS New Jersey State Director.

“Also evident were his unique talents to train and mentor these team members, substantially expanding the strength of the organization,” Washburn said. “Dave made a difference in innovative ways through this role. He worked on the HQ senior staff for many years as well. Chief Army MARS Paul English and I are most grateful for his long and valued MARS service.”

A former FCC field inspector who also served as an ARRL Official Observer, Popkin has made similar contributions to Amateur Radio, Washburn said, citing Popkin’s years of leadership with the New Jersey Phone Net and with the Englewood Cliffs (New Jersey) Amateur Radio    Club’s ARRL Field Day operation.

The President’s Volunteer Service Award is a civilian honor bestowed by the President of the United States. Established by executive order by George W. Bush, the award was established to honor volunteers who give hundreds of hours per year helping others through the President’s Council on Service and Civic Participation. The award can be granted to individuals, families and organizations in the US to recognize more than 4,000 hours of extraordinary service as a volunteer. — Thanks to Carver Washburn, W2TFM/AAA2RD

AE4FH Interviews Hans from QRP Labs About the QSX SDR Transciever Kit

Wed, 08/15/2018 - 13:43

“YOTA 2018 South Africa is now over, and one of the highlights of the youngsters’ week were the kit building sessions. They had the opportunity to build one of three kits, one of which was the newly-introduced QSX SDR transceiver kit. This kit, which was designed by Hans Summers (G0UPL) of QRP Labs (http://qrp-labs.com), and it will be available in the near future. Hans generously donated the kits and his time to YOTA so the youngsters would have a fantastic kit to make and take home, so we decided to do an interview with him so hams around the world could learn about his kits and his company. Please take the time to watch the entire video to learn more about the kit.”

HDSDR VERSION 2.80 BETA RELEASED

Wed, 08/15/2018 - 11:12

HDSDR is a freeware Software Defined Radio (SDR) program for Microsoft Windows 2000/XP/Vista/7/8/8.1/10.

Typical applications are Radio listening, Ham Radio, SWL, Radio Astronomy, NDB-hunting and Spectrum analysis.

HDSDR (former WinradHD) is an advanced version of Winrad, written by Alberto di Bene (I2PHD).

After a long hiatus, development of HDSDR got going again in early2017 with versions 2.70 and 2.76, followed by 2.76a in March 2018. Now, version 2.80 is outin public beta, and there is every reason for HDSDR users to upgrade. The upgrade is a mix of new or enhanced functions, and a modest (as always) change to the graphical user interface (GUI).

I have talked with the team for the last year or so and sent a few suggestions which would improve my use of HDSDR. I’m happy to see some of them well taken care of, and otherchangeshave beenaddedtoo.Graphical User InterfaceIf we start off with the visual appearance,the lower left “Control Centre” if you like, has been rearranged a bit. For the first time since the Winrad days, the mode controls are different with the indicator “lights”moved below the text, allowing for smaller controls so the FreqMgr function could move up.

Also, the ExtIO function was moved to the F column to the left, renamed and assigned to the F8 key. Help/Update has been removed, but no worries, if you press F1 it’s still available. All this reshuffling opened room for two very useful additions: The Frequency Band selector, and most important of all in my view, the Frequency Step selector, which has moved away from its convoluted position within Options. Moreover, the Frequency Step (tuning step) function is now preassigned by band, so if you tune a SW broadcast band the default frequency or tuning step is 5 kHz. On MW, it’s 9 or 10 kHz depending on which ITU zone you have assigned in FreqMgr. One thing I particularly like with HDSDR is that the tuning steps are not mode-dependent.

Another newfeature is that during playback, frequency and mode are displayed together with the file data. Now why would you want that, with the information already available just above? It is because blind users are not able to see both the frequency and the running time simultaneously. By adding frequency to the same line, they can. Universal design

– fully integrated band management (ITU 1+2+3)
– FreqMgr: HFCC frequency list (import)
– FreqMgr: EiBi+HFCC FindMatch checks Time, AutoFindMatch
– band selection / frequency step on main window
– Misc option: Auto-LO
– Misc option: keep Tune when LO is changed
– Auto Band Zoom (Options -> Visualization -> RF)
– Mouse Wheel option “Zoom RF”
– Forwards button for WAV files
– WAV buttons << and >> operate without WAV file
  { left click: Band +/- } { right click: Tune +/- step }
– auto subdirectories for recording
– more options for digital mode application (Options -> DigiMode Settings)
– more command line options (-lo, -tune, -mode, -rec with recording time)
– drag and drop for wav files
– split for TX (SDR-TX only!)
– slow speed for AF display
– Autosave AF waterfall {CTRL+Shift+X}

A Pair of Coronal Holes & a Probe: Solar Storm Shortie 08-14-2018

Tue, 08/14/2018 - 17:34

“Be sure to watch to the end for a Parker Solar Probe Dedication! aurora shows, especially at high latitudes. Two coronal holes are rotating through the Earth-strike zone, which means Earth will be preconditioned for activity! The news for amateur radio operators is not so great, as the last remaining bright region on the Earth-facing Sun rotates to the Sun’s backside out of view. Solar flux has dropped and we are back at poor levels for radio propagation on Earth’s dayside. Unfortunately, these conditions could easily continue over the next week or more. Learn the details of the coming solar storm, see why GPS users are smiling, and why “CW” for amateur radio operators may be the mode of choice.”

New FCC Part 95 Personal Radio Services Rules Published in The Federal Register

Tue, 08/14/2018 - 13:16

Reorganized and updated FCC Personal Radio Services (PRS) Part 95 rules have been published in The Federal Register. Among other things, the PRS covers the Family Radio Service (FRS), General Mobile Radio Service (GMRS), and the Citizens Band Radio Service (CBRS).

The revised rules allot additional FRS channels and increase the power on certain FRS channels from 0.5 W to 2 W. FRS channels are in the 462.5625 – 462.7250 MHz range.

Effective September 30, 2019, it will be illegal to manufacture or import handheld portable radio equipment capable of operating under FRS rules and under other licensed or licensed-by-rule services. The FCC no longer will certify FRS devices that incorporate capabilities of GMRS capabilities or of other services. Existing GMRS/FRS combination radios that operate at power levels of less than 2 W ERP will be reclassified as FRS devices; existing GMRS/FRS radios that operate above that power level will be reclassified as GMRS devices, requiring an individual license.

Radios that can transmit on GMRS repeater input channels will continue to be licensed individually and not by rule.

Once the new rules are effective, CBers will be allowed to contact stations outside of the FCC-imposed — but widely disregarded — 155.3-mile distance limit.

Storm Takes Down Antennas at Memorial Ham Station on Swedish-Norwegian Border

Tue, 08/14/2018 - 07:43

The SJ9WL-LG5LG Morokulien memorial station on the border of Sweden and Norway is off the air after a large tree, brought down during a severe storm on August 10, caused extensive damage to the station’s antennas. According to one report, the station’s 100-foot tower was broken into pieces after the tree fell across three tower guys. That pulled the support structure toward the station building, but a third set of guys on the other side of the tower held and kept it from damaging the structure. The tower has been up for at least a decade.

“This is a unique place, because the radio shack is exactly on the border, and the users are obliged to use the call signs alternatively — one day SJ9WL and the next day LG5LG,” Henryk Kotowski, SM0JHF, told ARRL. Kotowski has operated from the station in the past, and a photo he shot at Morkulien appeared on the cover of the October 1996 issue of QST.

“This was a memorial station devoted to SM5WL and LA5LG,” Kotowski explained. “They both promoted Amateur Radio and supported disabled hams. Swedish and Norwegian hams took over the abandoned border checkpoint house 50 years ago and made a joint club station there.” He said the area is now devoted to recreation and includes a peace monument. With funds from station rentals, the association Amateur Radio in Morokulien (ARIM) maintains and manages the station, which may be the only one located on an international border in what ARIM calls a “ham state.” The station is designed to accommodate individuals with disabilities. The name Morokulien is a combination of the words for fun — moro in Norwegian, and kul in Swedish — plus a suffix indicating “in one place.”

Antennas on the support structure included an eight-element log periodic for HF plus a 6-meter Yagi and antennas for VHF and UHF. The antenna structure was topped with a VHF-UHF vertical. The tower also supported dipoles for the lower bands.

“Sweden has been haunted this summer by drought, wildfires, and, recently, heavy storms and rainfall,” Kotowski recounted.

The cottage in Morokulien had been booked for the weekend, but the reservation was canceled. This fall, clubs on both sides of the international border are planning a joint 50th anniversary celebration.

HAARP’s WSPR Research Campaign Yields Hundreds of Reports on 40 and 80 Meters

Mon, 08/13/2018 - 10:42

Just-completed research at the High-Frequency Active Auroral Research Program (HAARP) transmitters in Gakona, Alaska, successfully took advantage of the WSPR digital protocol and the Weak Signal Propagation Reporter Network (WSPRnet) on July 30 through August 1. University of Alaska Fairbanks (UAF) Space Physics Group researcher and HAARP Chief Scientist Chris Fallen, KL3WX, told ARRL that the research — HAARP’s fourth research campaign under management of the University of Alaska Fairbanks — went well.

“My ‘citizen science’ experiments were funded by the National Science Foundation and were conducted for approximately 30 minutes at the end of each campaign day,” Fallen told ARRL. “They consisted of 2-minute transmissions using the WSPR digital mode in the 40- and 80-meter bands, with a 2-minute off period between transmissions.” He said HAARP transmitted in full-carrier, double-sideband AM because it does not have SSB capability. HAARP operated under its Part 5 Experimental license, WI2XFX, with Special Temporary Authority (STA) from the FCC to transmit on amateur bands.

“I systematically varied the HAARP transmission parameters, such as gain, net power, beam direction, and polarization, to see how they affected the reception reports collected in the WSPRnet.org database,” Fallen said. “During the 3 days, we gathered more than 300 confirmed reports of signal strength and location from nearly 100 unique participants throughout Canada and the US.”

Fallen said the spots, collected along with the corresponding HAARP transmission parameters, are available online, (1) and (2). He said the spreadsheet at the second link is editable by the public, “specifically by citizen scientists who want to manually add their spot or other interesting data analysis,” he added. “In this sense, the experiment continues.”

He said that HAARP’s low-elevation transmissions on 40 meters resulted in the greatest number of spots. “The 40-acre phased array antenna at HAARP, with its vertically oriented normal, is not designed for low-elevation transmissions, and so these directional experiments most likely included significant grating lobes in the opposite directions,” Fallen explained. “The most distant spot was located at grid EL96xi, near Boca Raton, Florida, reported by W1NEJ, from a distance of 6,154 kilometers. Interestingly, HAARP was aimed in the magnetic west direction during that spot. Those grating lobes!” A grating lobe occurs when the signal is steered too far with a phased array and the main beam reappears on the opposite side.

Fallen said a few Alaskans participated in the test, and all spots from there were on 80 meters, with the exception of a single 40-meter spot reported by KL4IU, located near Fairbanks. “KL4IU used a 30 MHz turnstile antenna recycled from the old Poker Flat Research Range imaging riometer, essentially a phased array HF receiver, that was destroyed by lightning many years ago,” he said.

HAARP and the Arecibo Observatory in Puerto Rico are planning to conduct heating campaigns this fall, Fallen noted, although not at the same time, as experimenters are shared.

Funding agencies for the recent HAARP research campaign included the National Science Foundation, Air Force Research Laboratory, and the Office of Naval Research, with experimenters from the Naval Research Laboratory, Air Force Research Laboratory, Eastern Michigan University, Cornell University, Virginia Tech, and the University of Alaska Fairbanks.

HAARP is holding its annual open house on August 25.

A New FT8 with Rag Chew Abilities ( FT8CALL )

Mon, 08/13/2018 - 07:45
FT8 has taken over the airwaves as the digital communication mode for making QSOs over HF/VHF/UHF. The mode has been widely popular as the latest offering in K1JT’s WSJT-X application. FT8 stands on the shoulders of JT65, JT9, and WSPR modes for weak signal communication, but transmits much faster with only slightly reduced sensitivity. While FT8 is an incredibly robust weak signal mode, it is designed heavily to take advantage of short band openings on HF/VHF/UHF and only offers a minimal QSO framework. However, many operators are using these weak signal qualities to make successful QSOs on the HF bands where other modes fail.

The idea with FT8Call is to take the robustness of FT8 mode and layer on a messaging and network protocol for weak signal communication on HF, similar to FSQ and Fldigi with a keyboard-to-keyboard interfac

Read more on the design inspiration here: https://github.com/jsherer/ft8call

 

For release announcements, join the FT8Call mailing list here: https://groups.io/g/ft8call

Notice

FT8Call is a derivative of the WSJT-X application, restructured and redesigned for keyboard-to-keyboard message passing. It is not supported by nor endorsed by the WSJT-X development group. While the WSJT-X group maintains copyright over the original work and code, FT8Call is a derivative work licensed under and in accordance with the terms of the GPLv3 license. Source code can be found in this public repository: https://bitbucket.org/widefido/wsjtx/

Install

FT8Call currently comes in a variety of builds.

 

  • Desktop Linux (64-bit x86_64, Ubuntu 18.04 AppImage) v0.4.2
  • Desktop Linux (64-bit x86_64, deb) v0.4.2
  • Desktop Linux (32-bit i386) v0.4.2: [not yet available]
  • Raspbian Stretch (armv7, AppImage) v0.4.2
  • Raspbian Stretch (armv7, deb) v0.4.2
  • Windows 10 (win32_64) v0.4.2
  • Mac OSX (x86_64) v0.4.2: [not yet available]

 

For the most up-to-date listing of build downloads, check the FT8Call release announcements and FT8Call Release Downloads Wiki. Of course, you are always free to take a look at the source code as well!

 

The application is distributed using the WSJT-X installer on Windows. For Linux, it is distributed as an AppImage, a single file executable that can be run portably on your Linux desktop or RaspberryPi, as well as a .deb. AppImage is an untraditional approach to distributing Linux software so if you’ve never dealt with an AppImage before, all you need to do is:

 

  1. Download the AppImage for your platform
  2. Set the AppImage file to be executable
  3. Run the AppImage file
  4. Profit!

 

NOTE: Until the general release of FT8Call, development versions will only carry a 10 day lifespan. After expiration, you’ll be required to upgrade to the latest version of the application.

Operation

If you’ve used Fldigi or WSJT-X before, you’ll feel right at home with FT8Call. The premise is that FT8Call changes the encoding structure of FT8 modulated messages, breaking up long freetext messages into multiple transmission frames / cycles.

 

Most operators testing the application can be found +/- 4-8kHz from the standard FT8 frequencies. It is essential to avoid the main FT8 frequencies, as that will cause confusion among WSJT-X operators. Here are some frequencies to use instead:

 

  • 160m:  1.838 MHz //  2 kHz below FT8
  • 80m:  3.580 MHz //  7 kHz above FT8
  • 40m:  7.080 MHz //  6 kHz above FT8
  • 30m: 10.130 MHz //  6 kHz below FT8
  • 20m: 14.080 MHz //  6 kHz above FT8
  • 17m: 18.104 MHz //  4 kHz above FT8u
  • 15m: 21.080 MHz //  6 kHz above FT8
  • 12m: 24.920 MHz //  5 kHz above FT8
  • 10m: 28.080 MHz //  6 kHz above FT8
  •  6m: 50.300 MHz // 13 kHz below FT8

 

You can use the mailing list Sked Chat or the Facebook group to schedule on other frequencies with test operators.

Band Activity

Band activity is displayed on the left. Callsigns you’ve heard CQing are on the right. Clicking either of those will move your RX/TX offset to that audio frequency (QSY).

There is a waterfall at the bottom of the screen to show you the signals in your audio passband.

  Messages

The top yellow text box shows you messages that are either on the frequency offset you’re on or who have directed a message to you (they sent a message that included your callsign).

You type into the white box on the bottom to prepare a message for transmission. Normal FT8 character restrictions do not apply! The extended character set includes all printable uppercase ASCII (A-Z 0-9 Space ./?+-`~!@#$%^&*()_=[]\{}|;’:”,<>). The message structure is variable encoded, so the most common characters take the least amount of space, and special characters take longer to send.

As you type your message you’ll see the send button display the number of frames (15 second transmit cycles) it’ll take to send your complete message. All you have to do is click send (or hit enter) to start transmitting on the next interval. As each frame is transmitted one after the other, the button will update with the number of frames left.

Because of this special variable encoding, messages in FT8Call cannot be decoded by WSJT-X. The same is also true, WSJT-X messages will not be shown in FT8Call.

 

Messages come in two forms:

  1. standard FT8Call free text messages
  2. directed FT8Call messages
  Standard Messages

Standard messages are freetext messages that do not start with a callsign or a directed command. These messages will only print at another’s station location if they align their receive offset within 10Hz of your transmit offset. This is operation similar to other keyboard-to-keyboard digital modes, like Olivia, RTTY, and PSK.

 

Directed Messages

Directed messages are special FT8Call transmissions that automatically prefix your message with your callsign, similar to how FSQCall operates. Directed messages are useful for communicating in that you do not have to include your callsign in your message, allowing you to use more of the transmission frame(s) for actual message text, as well as alerting the recipient that a message was sent to them. As long as you are in the same passband, you do not have to be on the same frequency offset to receive a directed message.

 

To send a directed message, all you need to do is include the callsign of the receiving station as the first word in the message. There is a special “ALLCALL” callsign that you can use to send the message to anybody who is able to receive your message. Some examples:

 

  • DR4CNK HELLO HOW ARE YOU JIM?
    • Will be sent as:   KN4CRD: DR4CNK HELLO HOW ARE YOU JIM?
  • ALLCALL HELLO NET PSE QSY 14300
    • Will be sent as:   KN4CRD: ALLCALL HELLO NET PSE QSY 14300

 

You’ll notice a special character at the end of the message, ala ⌁. It is a symbol to indicate the End of Transmission, the last frame of the message has been transmitted with nothing else to follow. This means you get a visual indicator that the transmission is done and you can begin transmitting a reply.

 

There are special directed messages that you can send to stations to have them automatically reply if they have AUTO enabled. They are comprised in the form of [CALLSIGN][COMMAND].

 

Available commands:

 

  • ? – What is my SNR?
  • @ – What is your QTH (station location)?
  • & – What is your QTC (station message)?
  • % – What is your station power?
  • $ – What stations are you hearing? (Top 4)
  • |message – Please ACK and retransmit the following message
    • The message is retransmitted by the receiving station  verbatim with the addition of “DE [CALLSIGN]” added to the end of the message…meaning you do not need to add it to your message.
  • !message – Please display this message in a alert dialog and ACK if acknowledged
  • #message – Please ACK if you receive this message in its entirety
  • AGN? – Have the station automatically retransmit their last message

 

Examples:

 

If I wanted to ask DR4CNK what his QTH was, I’d send:

  • DR4CNK@
    • And he would respond with a directed message back to me: “DR4CNK: KN4CRD MY QTH IS SOUTH OF FRANCE”, automatically if AUTO reply is enabled.

 

You can also use “ALLCALL” with the “?” command and all stations that receive your message will respond on a random frequency offset, example:

 

  • ALLCALL?
    • And all stations who heard your message would respond with your signal strength:
      “DR4CNK: KN4CRD SNR +21”

 

If I wanted to transmit a message to OH8STN through DR4CNK, I could use the retransmit command and send:

 

  • DR4CNK|OH8STN HELLO JULIAN!
    • During retransmit, at each hop the originating sender’s call is appended to the message.
    • The command above would be received by OH8STN, they would send an ACK back, then retransmit the message, like so:
      • My station sends:
        KN4CRD: DR4CNK|OH8STN HELLO JULIAN!
      • DR4 station acks and retransmits:
        DR4CNK: KN4CRD ACK
        DR4CNK: OH8STN HELLO JULIAN! DE KN4CRD

 

If I wanted to alert a message to LB9YH through OH8STN through DR4CNK, I could send:

 

  • DR4CNK|OH8STN|LB9YH!HEY KEN!

 

You can also mix and match standard and free text messages, but most of the time you won’t need to.

 

BCN – Beacons

There is an automated beacon that transmits on an interval once turned on (BCN button on the top right). This interval can be changed in the settings. There’s no protection against the beacon transmitting over a message you’re receiving, so you’ll have to keep an eye on it. All beacons are transmitted on your current frequency unless it is not free, in which case a random (unused) frequency free offset between 250Hz-1500Hz.

The intent of beaconing is not to report on propagation…it’s to help populate your heard list (on the right) so you know who’s likely to be reachable so you can try to make contact. You can’t work them if you can’t “hear” them.

 

AUTO – Automatic Replies

While auto is enabled, your software will automatically respond to directed queries, like “?”, “@”, and “&”. When auto is turned off, FT8Call will buffer responses in the send message textbox until you are ready to send the replies manually.

 

LOG

There’s a log button in the top right. You’ll have to fill out all of that information manually since the QSO is freetext and not automated.

 

SPOT

FT8Call will report callsigns you hear (or your callsign if heard by other stations) to PSKReporter.com under the “FT8CALL” mode.

 

MACRO

There are a few quick macro buttons for entering common messages. You can edit these in the settings window. Just be mindful that long macros will take a while to send.

 

Frequencies

If you want to transmit on a non-standard frequency (recommended) you can either modify the frequencies list in the settings, or you can type directly into the band dropdown box in the top left of the screen.

ips & Tricks
    • An example QSO:
      • KN4CRD: CQCQCQ EM73
      • DR4CNK: KN4CRD SNR +01 GOOD SIGNAL ⌁
      • KN4CRD: DR4CNK SNR -12 TU 4 FT8CALL RIG IS KX2 5W DIPOLE

 

  • DR4CNK: KN4CRD RR -22 FB KX3 100W VERT ⌁
  • KN4CRD: DR4CNK RR FB REALLY ENJOYING THE CHAT MODE WITH LONG MESSAGES. BUT HEY LET’S TRY A RELAY
  • … (and on, and on, if you want)

 

    • KN4CRD: DR4CNK 73
    • KN4CRD: CQCQCQ EM73
  • You do not need to include your callsign when initiating your directed replies. They will be prefixed to your message automatically.
  • You do not have to reply on the same frequency offset as the caller. But, if you’re calling another station off their frequency, you do need to include their callsign at the beginning of the the message so it is directed to them and will show up in their yellow directed activity window.
  • Directed messages pack as much data as standard FT8 frames. The following examples are all 1 transmit cycle long
    • Example:
      • KN4CRD/P: CQCQCQ EM73 (1 transmit frame)
      • KN4CRD: ALLCALL? (1 transmit frame)
      • DR4CNK: KN4CRD SNR +15 (1 transmit frame)
      • DR4CNK: KN4CRD AGN? (1 transmit frame)
  • For replying to a station’s CQ, double click their call in the call activity window, then either choose a directed command or type a message to them:
    • DR4CNK: KN4CRD SNR +12
    • DR4CNK: KN4CRD YES
    • DR4CNK: KN4CRD NO
    • DR4CNK: KN4CRD RR
    • DR4CNK: KN4CRD 73
    • DR4CNK: KN4CRD HELLO MY FRIEND GREAT TO HEAR YOU!
  • You can send freetext at any time! That’s what FT8Call is for:
    • HI JIM TU 4 CALL UR -12 INTO ATLANTA BTU DE KN4CRD (4 transmit frames)
  • It might be helpful to learn some of the morse code prosign/abbreviations and psk31 abbreviations:
Frequently Asked Questions
  • What are the random three (or six) characters at the end of my retransmit and alert commands?
    • These are a checksum for the message added to ensure all of the message frames were delivered correctly before retransmitting / alerting. If received in its entirety by the receiving station, these checksums will not be displayed to them.
  • Beacons transmit back to back (30 seconds). Why? Is this normal?
    • Yes. They currently transmit for 30 seconds to compensate for band fading.
    • In the future, beacons that transmit for 30 seconds may be able to offer extra information during the beacon (things like compound callsigns, extra long grid locators for telemetry, station power, etc)
  • You said that all printable ASCII characters can be used. Do some take more space than others?
    • Yes. The characters that are sent in the messages are variable encoded, ranging from 3 to 19 bits in length based on their probability of being used in a sentence. The most common characters take the least amount of space, allowing us to send more than 13 characters per transmission cycle on average.
    • Example: Space and E are only 3 bits in length. You could send about 22 (!!) of them in a single transmission. Whereas a character like { is 14 bits in length, you could only send 4 of those. (But really, how frequently do you use that character?)
    • Here are some examples of phrases that could be sent in one 15 second transmit cycle:
      • EEEEEEEEEEEEEEEEEEEEEEE (23 characters)
      • I HAVE EATEN A SHOE (19 characters)
      • WHICH WAY TO OHIO (17 characters)
      • NEVER HAVE I EVER (17 characters)
      • TU UR 599 INTO (14 characters)
      • Etc
  • How fast does FT8Call transmit?
    • FT8Call uses the same 15-second transmission cycle as FT8. What is different is that due to the variable encoding of the characters, FT8Call can transmit up to 23 characters per transmission frame. For average sentences, FT8Call can pack words very tightly, at around 10-15WPM.
    • Example:
      • “WE HOLD THESE TRUTHS TO BE SELF-EVIDENT THAT ALL MEN ARE CREATED EQUAL THAT THEY ARE ENDOWED BY THEIR CREATOR WITH CERTAIN UNALIENABLE RIGHTS THAT AMONG THESE ARE LIFE LIBERTY AND THE PURSUIT OF HAPPINESS.”
        • This phrase is 35 words. It would take 13 transmission cycles to send (3 minutes 15 seconds). That is just under 11 WPM.
      • CW has a neat way of calculating WPM, timing how long it takes to transmit the word PARIS. In FT8, PARIS is encoded into 24 bits (4.8 bits/character). Each transmission cycle can pack up to 69 character bits. That equates to about 11.5 WPM. (69/24=2.875 words / 15seconds * 4)

SmartSDR for iOS v2.6.2 Now Available

Sun, 08/12/2018 - 09:11

FlexRadio Systems announces the release of SmartSDR for iOS v2.6.2 is now available for download or update from the Apple App Store.

This App requires a FlexRadio Systems FLEX-6000 Signature Series Software Defined Radio (SDR) Device. However, the App also contains a FlexRadio Simulator (Demo Mode) that provides an approximation of the App’s features so you can evaluate this App even without owning a FLEX-6000 SDR.

This version includes the following changes and improvements:

■ Local Headsets Monitoring

Normally the MON button only works remotely (on the Radio). Now, local Headset Microphone input can also be monitored. You can turn on and adjust the monitor Volume from the Settings screen.

■ DX Cluster filters

Filters have been improved. It is now possible to filter not only by Band and Mode but also by Comment, CQ-Zone, ITU-Zone, Call Prefix and Country.

The Mode filter now also supports FT8, JT65, JT9 and WSPR.

■ Spot Details on Panadapter

Now, you can double-tap on a Spot on the Panadapter to get Details about the Spot including QRZ/HamQTY lookup. Tapping once still adjusts the active Slice to the spot.

■ Support for the following languages: Spanish, French, Italian, Netherlands, Japanese, Chinese (Traditional and Simplified)

Please note, if you are not happy with a translation, just change back to English (in the Settings of the App) and/or contact me to help and improve the translations.

■ Listen only mode added

This mode allows, for example, to use Speakers or Headphones in Stereo mode if they don’t support Stereo along with Microphone usage.

■ Band Zoom feature added

For this, two new buttons have been added under the left BT menu.

■ Possibility to use a hardware keyboard

If you have a hardware keyboard attached (Bluetooth or iPad Pro Keyboard) you can now press Space to toggle PTT, use the , or . keys to change the frequency or press Buttons 1 … 9 to activate Voice Macros.

■ Several MIDI Controller fixes and improvements

The CMD-Micro and Hercules controllers are now working way better than before (TNX Doug!).

A new sensitivity setting has been added to reduce the Wheel sensitivity independent from the Step value.

■ Improvements for all Controllers (Midi,Flic,PowerMate)

Now, SplitMode, Band Zoom, Bandwidth, WNB as well as NB values and WNB values and even global Profiles can be selected.

■ Button to squeeze / expand the Voice Macro button bar and CWX Window

Now, you can squeeze the Macro button bar and CWX Window to save space.

■ Transverter “LO Error” now in MHz not Hz

■ CW Straight Key and Paddle improvements

Now, keying is no longer interrupted when moving the finger.

The CWX screen can now be moved further down to cover the TabBar so they can’t be accidentally hit.

■ Fixes and improvements of the +/- Split function

The RX Slice remains Active slice after enabling Split mode.

The RX Slice becomes again TX Slice after disabling Split mode.

■ Some Slice Flag Changes

S-Meter is now Colored.

When transmitting, the S-Meter changes to Level meter on the TX Slice.

This App is still backward compatible to Version 1 of SmartSDR or can run with the latest SmartSDR version, including SmartLink.

SmartSDR for IOS v2.6.2 is available free of charge.

NIST FY 2019 Budget Would Eliminate WWV and WWVH

Sat, 08/11/2018 - 15:07

The National Institute of Standards and Technology (NIST) FY 2019 budget request includes shutting down “NIST radio stations in Colorado and Hawaii” — in other words, WWV and WWVH. Radio amateurs, HF listeners, and others around the world routinely make use of the time and frequency standard signals, which also include propagation information. NIST said eliminating funding currently “supporting fundamental measurement dissemination” would include putting WWV and WWVH off the air for a saving of $6.3 million. The overall NIST FY 2019 budget request is $127 million, which, the agency said, is a net decrease of $49 million from FY 2018 levels.

“The proposed reductions will allow NIST to consolidate and focus on narrower core [fundamental] measurement programs while meeting budget levels,” the agency said in its FY 2019 budget summary. “NIST will focus on basic research while reducing funding for efforts applying some of its breakthroughs into new measurement applications.

The FY 2019 proposed budget cuts developed earlier this year came to light via Tom Witherspoon, K4SWL, who maintains The SWLing Post website, after a number of viewers called it to his attention. He posted an article on his blog.

“I’ve always considered WWV and WWVH to be the heartbeat of the shortwaves here in North America — a constant, timely companion and brilliant gauge of HF propagation,” Witherspoon wrote. I assumed both stations would be some of the last to go silent on the shortwaves.”

NIST said other “illustrative” cuts in the FY 2019 budget include:

  • $3.5 million for Lab to Market, which seeks to accelerate technology transfer from federal laboratories
  • $6.6 million in environmental measurements projects across NIST laboratories, including work measuring the impact of aerosols on pollution and climate change, and gas reference materials used by industry to reduce costs of complying with regulations
  • $5.8 million eliminating the NIST Greenhouse Gas (GHG) Measurements program, including Urban Dome research grants to advance the direct measurement of GHG emissions on the scale of cities or regions.
  • $6.7 million in forensic science, reducing the program size to $7.3 million by prioritizing measurement science in the NIST labs and eliminating program management functions and external grants for the Organization of Scientific Area Committees for Forensic Science and the Forensic Science Center of Excellence 
  • $4.1 million in R&D targeting application of NIST quantum breakthroughs to applied measurement needs, including temperature and atmospheric gas metrology

“I find this budget request very disappointing,” Witherspoon said with respect to the proposed elimination of WWV and WWVH. “Let’s hope, somehow, this does not come to fruition.” He said The SWLing Post would be tracking and posting any new developments.

Updating the Firmware – Icom IC-7610 [ VIDEO ]

Fri, 08/10/2018 - 13:21

Step by step instructions showing how to update the firmware using a USB thumb drive

Faint signals are no longer a challenge for DXers and Contesters around the world, with the new IC-7610. The difference between putting the QSO in the log or trying another time is the capability of your receiver. The high performance RMDR in the IC-7610 has the ability to pick out the faintest of signals even in the presence of stronger, adjacent signals. The IC-7610 introduces dual RF direct sampling receivers. Achieving 100dB RMDR, these receivers rival that of other top-of-the-line transceivers. The IC-7610 also comes with a high-speed, high-resolution, real-time spectrum scope on a 7-inch color display.

RF Direct Sampling System

The IC-7610 employs an RF direct sampling system, where RF signals directly convert to digital data and then processed by the FPGA (Field-Programmable Gate Array). This process reduces distortion that naturally occurs in the various mixer stages found in traditional superhetrodyne receivers.

The RF Direct Sampling System in the IC-7610 is capable of 110 dB* RMDR. This performance gives you the ability to pull weak signals out of the noise of strong adjacent signals. There is a difference you can actually hear as the desired signal comes out of the pileup!

Independent Dual Receiver

Whether listening to both sides of DX station running split, or looking for a multiplier on a different band or mode, the dual receivers in the IC-7610 have you covered. Two separate DIGI-SEL preselectors, two separate Band Pass Filter networks, feed two separate A/D converters into the FPGA

Dual Digi-Sel

The DIGI-SEL preselectors are RF filters with sharp, narrow passband characteristics preventing Analog-to-Digital Converter overflow from large out-of-band signals when sampling the RF signals. Additionally the third and higher order IMD components are reduced. This is ideal when strong signals are received in a contest pile-up or from broadcast stations on adjacent frequencies or bands.

Large Color Touch Screen

The large 7″ color TFT touch LCD offers intuitive operation of functions, settings, and various operational visual aids such as dual spectrum scope aligned vertically or horizontally, simulated analog meters and RTTY, PSK31/63 mode decoded messages.

The combination of the touch screen and the multi-dial knob offers quick and smooth operation. When you push the multi-dial knob, menu items are shown on the right side of the display. You can select an item by touching the screen and can adjust the levels by turning the multi-dial knob.

Additional Features:
  • Built-in automatic antenna tuner
  • Digital-Up-Conversion (DUC) for clean transmit
  • Dual receivers, dual spectrum scopes
  • DVI-D connector for an external display
  • SD memory card slot for saving data
  • I/Q signal output
  • Memo pad stores up to 10 operating frequencies and modes
  • Quick split function
  • Quick Dualwatch function
  • RF gain and squelch control with a knob
  • RIT and ΔTX variable up to 9.999 kHz
  • UTC/local clock and timer function
  • 1 Hz pitch tuning and display
  • Dial lock function
  • Adjustable main dial brake
  • External speaker jacks for Main and Sub receivers
  • Screen saver function
  • Multi-function meter (S-meter, Power, ALC, COMP, SWR, ID, VD and TEMP)
