UPDATE 10/2018 – ARRL

Florida ARES Teams Handle Hurricane Duty

Fri, 10/12/2018 - 16:09
 ARES Teams Handle Hurricane

Over the past week, Amateur Radio Emergency Service® (ARES®) teams in the ARRL Northern Florida Section went on alert and some activated to support emergency communication before and during Hurricane Michael.

Miller Norton, W4EMN, the Communications Watch Officer at the Duval County Emergency Operations Center (EOC) in Jacksonville, Florida, was monitoring SARnet — a UHF-linked repeater network in Florida — when he heard an urgent call for help that needed to be sent to the State EOC in Tallahassee. All other forms of communication were out, but Norton was able to relay the message to via Amateur Radio. He also passed along messages and requests from the Jackson County EOC to the American Red Cross. Norton said officials in Tallahassee and Jackson County were both “incredibly grateful” for the way the SARnet system functioned during the weather emergency.

Jackson County Emergency Coordinator Ricky Whittington, KD4AST, deployed to the county EOC in Marianna.

“We took a direct hit by the center of the storm at 140 MPH,” he told Clay County ARES Assistant Emergency Coordinator (AEC) and Public Information Officer Scott Roberts, KK4ECR. “[The] county maintenance building across the road from the EOC was picked up and slammed into the north side and over the roof of the EOC just prior to the eye passing over.”

The incident took out the HF antenna, which has since been restored. Whittington said the internet failed, as did cell service for a while. Hams have been passing material and resource orders to the State EOC via HF and SARnet.

Whittington reported “total devastation of Bay, Jackson, and Gulf counties,” with loss of electrical power and water service, in addition to damage in Franklin, Holmes, and Leon counties. “[The] only mode of communications after the eye came across was ham radio, until we got minimal cell service a few hours ago,” he reported on October 11.

 

(adsbygoogle = window.adsbygoogle || []).push({});

ARES teams in other counties reported activations, although some teams remained in monitoring mode.

  • Escambia County ARES activated on October 9 at 2300 CDT to support two shelters — special needs and pet-friendly — until they closed on October 10 at 1700 CDT
  • Although the Alachua County EOC activated at Level I, the ARES volunteers never activated beyond Level 3. However, AEC Susan Halbert, KG4VWI, spent a day at the EOC coordinating with emergency managers in case they needed to open a shelter for local evacuees or for host county operation. No hams were needed for shelters, but one or two shelters opened for outside evacuees.
  • The Gilchrist County EOC activated at Level 2 and shelters opened. The local 2-meter repeater was excellent, and no power outages were reported. ARES primarily remained at Level 3 in monitoring mode. Daily nets were held for hurricane weather briefings and the Northern Florida Section Emergency Net on HF was able to provide up-to-date storm location information to the State EOC when it lost internet service.
  • Citrus County ARES was called to activate on Monday, October 9, at 5 PM CDT. At that time, emergency managers had opened four shelters, serving 38 clients (and 13 pets). Telephone and internet service remained operational throughout the weather event, although ARES volunteers staffed two shelters on a precautionary basis, as well as the EOC at activation. All shelters closed by 6 AM on Wednesday, October 11. Citrus County ARES volunteers covered two back-to-back 12-hour shifts at the EOC. ARES personnel stood down at 6 PM on Tuesday, October 10.
  • Duval County activated to Level 3 monitoring status along with the activation of the Duval County EOC. No shelters opened in Duval County, and there were no reports of serious damage.
  • Clay County also activated to Level 3 monitoring, when two tornadoes touched down in the county. No shelters were opened, and no official activations were requested.

N1MM- I/Q input to Spectrum Window – Ham Radio Logging

Fri, 10/12/2018 - 13:03
N1MM – Ham radio contest logging N1MM Logger is the world’s most popular ham radio contest logging program. For CW, phone and digital modes, its combination of contest-optimized features is unmatched.

I/Q input to Spectrum Window. I have an experimental version of the program posted in the Experimental gallery. It supports I/Q input. It has been tested with Airspy HF+, SDRPlay RSP1 and RSP2 and the IC-7610 successfully. Tests with an Elad radio were not successful. I am interested in what other SDRs people have that provide I/Q output that they would like to have supported. I am not interested in trying to support $20 dongles, I only want to support SDRs that are actually useful for contesting. Post below what SDR you have that has I/Q output. Please do not post non-SDR radios.hAM rADIO

IMPORTANT: The radio *must* have an ExtIO.dll provided by the vendor! Sound card output is NOT sufficient

Reported Russian Ham Band Intruders Continue to be Troublesome

Thu, 10/11/2018 - 13:32
Ham Band Intruders Ham Band Intruders

The International Amateur Radio Union Monitoring Service (IARUMS) reports interference on 40 meters from various Russian sources. The Russian coastal over-the-horizon (OTH) radar “Sunflower” was very active on 40 meters and audible in Europe in the evenings, transmitting FM on pulse. The site is believed to be northeast of Vladivostok. IARUMS Region 1 Coordinator Wolf Hadel, DK2OM, said it was monitored in September.

(adsbygoogle = window.adsbygoogle || []).push({});

In addition, a Russian ship was observed transmitted on 7,110 kHz on F1B with 50 baud and 200 Hz shift. The vessel was believed to be in the area around and east of Cyprus, on the air daily in September running F1B with 50 baud and 200 Hz shift. Another Russian ship was heard on September 18 transmitting AT3004D with 12 × 120 baud PSK2A on 7,179 kHz with a 2.6 kHz bandwidth in the area of Crete. And a Russian military system, believed to be near Moscow, was heard transmitting on 7,198 kHz in AT3004D test mode.

Elsewhere fishing crews often were monitored on 3,500, 3,535, 3,540, 3,560, 3,585, 3,590, 7,000 kHz, and 14,320 USB.

YUMA PROVING GROUND, Ariz. – Elements of the U.S. Army’s 1st Cavalry Division have begun testing a new armored vehicle for electronic warfare (EW) that has the ability to jam enemy communications systems and other emitters. The Drive reports. Continue reading original article

The Military & Aerospace Electronics take:

17 Sept. 2018 — As potential opponents — especially Russia — invest heavily in similar systems, the service is looking to reinvigorate its own EW capabilities, which largely eroded after the end of the Cold War.

Hurricane Watch Net Announces Plans as Hurricane Michael

Mon, 10/08/2018 - 13:02
Hurricane Michael

The Hurricane Watch Net (HWN) has announced tentative plans to activate on October 9 at 2100 UTC on both 14.325 and 7.268 MHz as now-Hurricane Michael is forecast to become a Category 1 hurricane later today. It is expected to make landfall somewhere on the Florida Panhandle on the evening of October 10 as a strong Category 2 or possibly a major Category 3 hurricane.

“However, don’t focus on the primary dotted line of the forecast track, as Mother Nature has a way of changing her mind as to where a storm can go,” HWN Manager Bobby Graves, KB5HAV, cautioned.

Now boasting sustained winds of 75 MPH, the storm is moving to the north at 7 MPH. The National Hurricane Center (NHC) said storm surge and hurricane watches are now in effect for portions of the northeastern Gulf Coast area. Some areas along the Florida Gulf Coast are especially vulnerable to storm surge, regardless of the storm’s exact track or intensity.

Graves said that given the current forecast track and forward speed, the HWN has tentative plans to activate Tuesday afternoon at 2100 UTC, remaining on 20 meters for as long as propagation allows and suspending operations on 7.268 MHz at 0300 UTC on Wednesday, October 10. Operations will resume at 1230 UTC on both 14.325 MHz and 7.268 MHz and will remain in operation until further notice.

At 1200 UTC on Monday, October 8, Michael was some 120 miles east-northeast of Cozumel, Mexico, and about 70 miles south of the western tip of Cuba. Watches and warnings are already in effect for parts of Mexico and Cuba. In addition to the storm surge watch for sections of the Florida and Alabama Gulf Coast, a tropical storm watch is in effect from Suwannee River to Anna Maria Island, Florida, including Tampa Bay, and for the Alabama-Florida border to the Mississippi-Alabama border.

 

(adsbygoogle = window.adsbygoogle || []).push({});

Hurricane conditions are expected over portions of western Cuba, where a hurricane warning is now in effect. Tropical storm conditions are expected today over the northeastern Yucatan Peninsula and the Isle of Youth, with heavy rainfall and flash flooding expected during the next couple of days.

Graves said the HWN remains available to provide back-up communications to official agencies such as emergency operations centers, Red Cross officials, and storm shelters in the affected areas. “We will also be interested [in collecting and reporting] significant damage assessment data back to FEMA officials stationed in the National Hurricane Center,” he added.

Music great Chet Atkins has died at home in 2001 Nashville, TN. Atkins was known worldwide for his distinctive guitar style, his easygoing manner, and his profound influence on the music world. Music fans may have known Atkins as “Mr. Guitar,” but to fellow Amateur Radio operators, he was W4CGP (ex-WA4CZD).

Chet Atkins
Birth name Chester Burton Atkins
Born June 20, 1924

Website www.misterguitar.com
Chester Burton “Chet” Atkins (June 20, 1924 – June 30, 2001), known as “Mr. Guitar” and “The Country Gentleman”, was an American musician, occasional vocalist, songwriter, and record producer, who along with Owen Bradley and Bob Ferguson, among others, created the country music style that came to be known as the Nashville sound, which expanded country music’s appeal to adult pop music fans. He was primarily known as a guitarist. He also played the mandolin, fiddle, banjo, and ukulele.

Atkins’s signature picking style was inspired by Merle Travis. Other major guitar influences were Django Reinhardt, George Barnes, Les Paul, and, later, Jerry Reed.[1] His distinctive picking style and musicianship brought him admirers inside and outside the country scene, both in the United States and abroad. Atkins spent most of his career at RCA Victor and produced records for the Browns, Hank Snow, Porter Wagoner, Norma Jean, Dolly Parton, Dottie West, Perry Como, Floyd Cramer, Elvis Presley, the Everly Brothers, Eddy Arnold, Don Gibson, Jim Reeves, Jerry Reed, Skeeter Davis, Waylon Jennings, and many others.

Rolling Stone credited Atkins with inventing the “popwise ‘Nashville sound’ that rescued country music from a commercial slump,” and ranked him number 21 on their list of “The 100 Greatest Guitarists Of All Time.”[2] Among many other honors, Atkins received 14 Grammy Awards and the Grammy Lifetime Achievement Award. He also received nine Country Music Association awards for Instrumentalist of the Year. He was inducted into the Rock & Roll Hall of Fame, the Country Music Hall of Fame and Museum, and the Musicians Hall of Fame and Museum.

Elecraft AX1 Multi-Band Whip Antenna

Sun, 10/07/2018 - 16:11
Elecraft AX1 – Portable HF antenna

Elecraft AX1 Ultraportable 17/20 Meter Antenna System (FAQ)

Q: What is the AX1?
A: The AX1 is a dual-band (20 and 17 meter) compact antenna system based on an optimized 2-piece whip.
It intended for use with lightweight transceivers such as the Elecraft KX2 an KX3 that are equipped with an
internal antenna tuner. The AX1 can be configured for HT-style or right-angle use as shown below.

Q: What type of operation is the AX1 designed for?
A: The AX1 is ideal for pedestrian mobile (/PM), where the radio is used hand-held (HT), or for lightweight
“HF Pack.” It can also be used during table-top or trail-friendly (TFR) operation, thanks to the supplied
BNC-L and anti-rotation bail. No poles, trees or other supports are required, so the AX1 can be deployed in
seconds. 17 and 20 meters are excellent bands for this purpose. With 5 to 10 watts, moderately good
propagation, and some patience, 1000 to 2000 mile contacts are commonplace, and DX contacts can also be
achieved. We’ve made many contacts with Europe and Japan from Northern California using the AX1
attached to a hand-held KX2 or KX3.

Q: Is an ATU required?
A: Yes. An ATU is required to resonate the antenna’s high-Q loading coil on each of the two bands. The
nominal resonance is in the 15 to 16 MHz range, allowing the ATU to achieve resonance at either 14 or 18
MHz (20 or 17 meters) with a low SWR. Both the KX2 and KX3 have internal ATUs that store network
settings per-band, allowing you to change bands instantly. (The ATUs have model numbers KXAT2 and
KXAT3 respectively.) Other whip antennas generally require changing coils or taps to cover more than one
band.

Q: Can the AX1 be used on other bands besides 20 and 17 meters?
A: There are two parts to this answer:
(1) If you’re willing to experiment with different loading coils, you could set the AX1’s resonance to any
desired frequency. This requires an antenna analyzer. Enamel wire with a 180-200 C rating must be used to
handle more than just a few watts. Standard enamel wire is rated at only 130-150 C.
(2) As designed, the AX1 may be usable on 30 and 15 meters—at reduced efficiency—because of the
wide matching range of the KX2 and KX3 internal ATUs. Achievable SWR on these bands will vary with
the length of the counterpoise wire and other factors.

Q: In what way is the AX1 “Ultraportable”?
A: The AX1’s base unit (2.5” long x 1” diameter) and telescoping whip (6” collapsed) are separate, allowing
the entire antenna system to fit into a small pocket or in very small carrying cases such as our CS40 and
CS60. Total weight is just 4.0 ounces. During operation, the AX1 can be attached directly to a radio being
used hand-held (HT-style), or used with a BNC-L and the supplied anti-rotation bail for table-top use.

Q: What is included with the AX1 antenna system?
A: The AX1 comes with:
• 3” base/loading coil with male BNC connector and
• counterpoise wire socket (for mini-banana plug)
• rugged 44” telescoping whip with 3/8”-24 threaded mount; collapses to 6”
• anti-rotation bail for table-top use
• BNC-L adapter for table-top use
• mini-banana plug for use with a counterpoise wire

Q: How is the anti-rotation bail used?
A: If you’re operating the radio on a flat surface, the AX1 is attached via a BNC-L adapter. The anti-rotation
bail is then installed so that it contacts the flat surface, thus preventing the whip from pivoting on the BNC-L
connector. The anti-rotation bail and BNC-L are not needed for hand-held (HT style) radio use.

(adsbygoogle = window.adsbygoogle || []).push({});

Q: How does the AX1 compare to other portable antennas?
A: The AX1’s performance is similar to that of other electrically short (~4 foot) whips. But it is more
versatile because it covers two bands, breaks into two small pieces for transport, has an attachment point for
a counterpoise wire, and includes an anti-rotation bail for table-top use. (Note: A modest-length wire-in-atree
antenna will generally outperform a short whip, and can be matched on more bands with the radio’s
ATU. So we recommend that, along with the AX1, you always carry two ~25-foot lengths of
stranded/insulated wire and a BNC-to-binding-post adapter. Use the wire antenna if you have time…and a
tree!…and you need maximum performance from your station.)

Q: Do I need a counterpoise wire? How long?
A: For transmit, you must use at least one counterpoise wire, for both safety and efficiency reasons.
Without one, your transmit signal will be typically 20 dB lower, and there may be more RF on the radio’s
chassis. We recommend a 13’ insulated/stranded “dragged” counterpoise wire for pedestrian mobile use.

Q: How much power can the AX1 handle?
A: The suggested maximum is 15 watts, though we’ve successfully tested it at 25 watts.

Q: Can the AX1 be used with other whips?
A: The AX1 will work any whip having a 3/8”-24 threaded base. If the whip is 44” long, the AX1’s normal
resonance will be preserved. A longer whip could be used to move the resonance point closer to 20 meters,
offering a slight improvement in performance. Resonant frequency must be determined experimentally.

Q: Could multiple AX1s be used to make a dipole, Yagi, etc.?
A: In theory, multiple AX1s could be used to make more complex antennas, and we may experiment with
this idea ourselves. However, since the AX1’s radiator is electrically short, performance will not be
comparable to full-size antennas, even it were elevated to ¼ wavelength above ground (the minimum
recommended for parasitic arrays). Also, the AX1 is intended to be used with an ATU. If used in a coax-fed
antenna of any type, the base loading coil would have to be carefully trimmed to achieve resonance on a
single band. Any parasitic elements would have to be adjusted as well.

Q: Can the AX1 be used in bicycle or mobile applications?
A: Bicycle mobile—yes. But not on any vehicle moving faster than about 20 MPH. The AX1 uses a BNC
connector and a telescoping whip, components that are not compatible with high wind loads.

JS8Call 0.7 Released

Sun, 10/07/2018 - 15:12
J8Call

“Howdy Folks, 

We’ve sure come a long way in the past few weeks. Thanks for sticking with me and enjoying the ride! This release is a pretty big one and I’m very excited to share it with you. Cut to the chase, and head over to the downloads page to grab your copy: https://groups.io/g/js8call/wiki/Download-Links So, what’s new in 0.7? First of all, like I said in my last email, the app is now called JS8Call and the mode is called JS8.

USB micro KEYER III – MicroHam

Sun, 10/07/2018 - 13:06

 

MicroHam

micro KEYER III is the world first and the only amateur radio USB interface featuring high dynamic range, 24-bit audio processing chain on all signal stages. It is the most powerful single radio All-In-One USB interface and the only USB interface to fully support digital and voice operation including microphone switching in one box.

With a single USB port, micro KEYER III works with any Windows-based logging or control program for CW, Voice, FSK and Digital operation (RTTY, FT8, WSJT, PSK31, SSTV, etc.).

micro KEYER III includes a CAT, radio control interface that supports all common standards A(RS-232, CI-V, Kenwood and Yaesu TTL), a powerful CW memory keyer using genuine K1EL’s WinKey, a Digital Voice Keyer for SSB, two channel audio processing for transceivers with dual receivers, automatic microphone selection, and a buffer/sequencer for amplifier or LNA control.

Compared to 16-bit audio interfaces, or to any USB enabled transceiver, including flagship transceivers from well known manufacturers (as of autumn 2018), unique 24-bit USB audio processing in the micro KEYER III provides advantage in higher dynamic range (>105dB), preserving transceiver performance also for audio processing on computer (digital modes), otherwise limited by 16-bit USB audio signal chain.

INRAD W1 competition headset

Sun, 10/07/2018 - 12:23
INRAD W1

*Photo N6MJ

New for 2018:  The INRAD W1 competition headset.  Following the successful introduction of the INRAD Desk Microphone System in 2017 and its excellent reviews from both the ham community at large and the ARRL‘s QST Product Review, we introduce this new unique headset for DXing, contesting, or general use on the air. 

THE INRAD W1

Ham radio never sounded so good!

  • Comfortable over-the-ear earpieces with large diaphragm high response speakers

  • Full stereo reception to allow use with dual receiver transceivers

  • 600 ohm dynamic microphone element on adjustable long boom with the best sounding headset transmit audio in ham radio

  • Unique headband tilt-back feature as used on pro broadcast headsets.

  • Extra wide and thick rubberized foam top padding for long stretches of wearing the headset while DXing or contesting

  • Light: weighs only 13 ounces. Avoid the neck and head fatigue associated with modified aircraft headsets sold by other companies.

  • Extra long straight + coiled cable with total length of almost 7 feet. 4 ½ feet straight + 1 ½ feet coiled + 1 ft straight. Coiled section can be stretched out an additional 2 feet if desired.

  • Rig mic jack adapters available for 8 pin modern Icom rigs, 8 pin Yaesu / Ten-Tec, 8 pin Kenwood / Elecraft, RJ-45 Yaesu, 3 pin TRS FlexRadio 6400/6600.

The right features for long hours of radio communication use.  

    •      Starting with comfortable over-the-ear earpieces.  Your ear goes inside the cup rather than having

earphone

    padding pushing your ear backward against the head, leading to pain after hours of use.  Headband fatigue is another potential problem with long-term headset use.  Modified aircraft headsets sold by others for ham radio use push down on the top of the head because they are heavy and lack adequate padding at the top.  We have solved this problem with two features.  First, thick rubberized foam padding at the top of the headband that molds to the head when in use.  Second, like broadcast headsets, the W1 has a tilt-and-click headband tilt feature.  The headband can be tipped back as far as 30 degrees off vertical without moving the earpieces, in addition to standard up/down movement of the band.
    •      Receive and transmit audio sound terrific.  Large diaphragm high response speakers provide clear, clean articulation of receive audio.  Stereo connector for use with dual receive transceivers if desired.  Transmit audio is from a 600 ohm dynamic microphone element that’s the correct impedance for your

HF transceiver

    and has excellent response from 50 Hz-15 kHz.   Sounds great for DXing, contesting, and general on-the-air use.
         Extra long straight and coiled cable from the headset to the radio.  7 feet total length.  4 feet of straight section, followed by 1 1/2 feet coiled for RF suppression, then 1 foot straight to the adapter for the radio mic jack.  Connect the 1/8″ mono transmit audio jack on the headset to an INRAD M-series mic jack adapter and you’re ready to operate.

The right price and the right customer service.

         Headsets are not treated gently.  They are a tool, and tools are made to be used.  Rough handling means headsets have to be well-built to stand up to it, and that the manufacturer will stand behind them also.  We offer a 1 year unconditional warranty for parts and labor.  We will repair or replace your headset at our option.  You only pay the shipping cost to send it to us.
      •      All the features you need in an

Amateur Radio headset

    • , plus the customer service and warranty to back it are available at the excellent price of only

 $179 plus shipping

    • .  M-series headset mic jack adapters, sold separately, are $14.95.

W1 is in stock and now shipping!

      The W1-B mic boom mic kit only and W1-E element only to be available later in October.

Gateway: 192.168.1.1

These are strictly default settings. You can modify any of these by going to XPORT web GUI via your web browser. We do not recommend changing any other parameters of the XPORT interface as loss of communication can be caused by doing so. There is no default user name or password. It is highly recommended to secure web interface with username and password.

For remote control and monitoring over LAN special software is needed. It is available free of charge, it can be downloaded from the following address: 
https://www.om-power.com/download/HF4_PA_Manager_v3.25-setup.exe.
