TS-890S – Kenwood

Tue, 12/11/2018 - 16:54
The most rewarding results often take place when faced with the harshest and most challenging conditions.
There are enthusiasts who know this all too well because of their love of DX. KENWOOD has the answer.
Achieve results through certainty and not circumstance. Delivered through impeccable receiver and audio performance.
This is our offering to you. Top in its class with three dynamic ranges.
Alive and well, the non-tiring KENWOOD tone keeps you listening. Receive performance on a whole other level from narrow bandwidth roofing filters that only full down conversion can provide

The TS-890S uses 8.248MHz 1st IF frequency down conversion for its receive signal system in order to continue the adjacent interference signal exclusion legacy refined in the TS-990S. This means you can use narrow bandwidth crystal filters with passband widths of 500Hz or 270Hz (optional YG-82CN-1) as roofing filters to achieve strong exclusion of unnecessary adjacent signals. The 1st mixer is the H-mode mixer also carried by the TS-990S. Conversion characteristics have been improved with fine-tuning of input/output matching as well the device used.

High-speed scanning with independent band scope receiver

The configuration of the band scope receiver has changed from the superheterodyne system used in the TS-990S to 1st IF sampling using an A/D converter (14bit/39MHz), and FPGA digital down conversion. This means a change in scanning method from step FFT to FFT, achieving highspeed updates to the display irrespective of span settings.

Local oscillator realizes superior C/N

Interference signal exclusion is not determined by roofing filters and signal system devices alone. The TS-890S has taken the VCO division of the TS-990S and developed it further, combining a VCO device with high C/N in the gigahertz band and a reference oscillation circuit with superior adjacent C/N to deliver C/N characteristics unattainable in conventional units.

The speed and quality of KENWOOD’s renowned IF AGC control

A variety of functions are realized through 32-bit floating-point DSP technology inherited from the TS-990S, including modulation/demodulation in all modes, IF filter, IF-AGC, and removal of interfering signals. Popular for its non-tiring and great-quality audio, the IF-AGC has undergone a facelift with a combination of roofing filters and IF filters, and has been designed to enable optimal control under various noise circumstances.

Evolved power to perform with diverse displays and auto-scroll.
A transmitter with stable output, quietness and high speed. Operational capacity reinforced with displays and various features

The seven-inch TFT color LCD is the same size as that used in the TS-990S. In addition to basic information including frequency, mode, and S-meter, the band scope and audio scope are also displayed. The TS-890S also displays further improvements in visibility and operability in tough usage scenarios such as competitions.

With the spectrum scope and waterfall screen display, the analogue meter is simultaneously displayed. The popular sub-scope display from the TS-990S has been incorporated as a filter-scope display

A band scope providing ease-of-ease

AUTO SCROLL MODE

In addition to conventional CENTER MODE and FIXED MODE, the unit comes equipped with an AUTO SCROLL MODE. While in FIXED MODE, if the receive frequency goes over the scope edge, then autoscroll will engage for half a screen width. Furthermore, with the EXPAND function turned on, the screen to be displayed next can be drawn in advance*. Also, with the SHIFT function, the receive marker can be set in the desired position on the vertical grid, which is convenient when displaying a non-receive frequency as the center display, such as for pileups during splits.

  • * Effective in spans under 200kHz. Image becomes slightly coarse when expanded.

Auto-scroll operation (span 10 kHz, EXPAND ON)
On the current screen (screen 2), if the frequency is changed to go over the top end of screen 2, it will automatically change to screen 3, and if it goes over the bottom end of screen 2, it will automatically change to screen 1. Waterfall screen creation normally commences after switching screens, but with the EXPAND function turned to ON, the display switches to the finished screen.

 CENTER MODE

When changing the receive frequency in CENTER MODE, there are many units that display a bright line that flows obliquely over the waterfall, but with the TS-890S, the bright line remains straight and enables tuning operation*. Switching to the follow display is also possible via the menu.

  • * During straight display, the waterfall bright line temporarily stops and undergoes parallel displacement. Image becomes slightly coarse when expanded.

● FIXED MODE

FIXED MODE allows you to switch between three kinds of display ranges with a single touch of the panel screen. The initial value is preset based on the band plan, but this can be easily adjusted to a desired scope.

Improved reference level operability ease-of-use

The TS-890S has improved operability of the reference level focusing on the visibility of the waterfall.

● Through optimization of each span, readjustment is mostly unnecessary when switching between them.*
● Settings are enabled for each band, and readjustment is also unnecessary for the PRE AMP ON and PRE AMP OFF bands.

  • * Spectrum scope waveform height changes during span switching.
Filter scope display

The popular sub-scope from the TS-990S is carried as a filter scope display. You can confirm receive filter selection status, roofing filter bandwidth, IF fi l ter passband information, receive for ex-audio spectrum, CW pitch frequency, and notch frequency all concentrated in one location.

Expanded touch operation scope

Basic operation of the TS-890S is through knobs and switches with a definite ‘clicking’ feel rather than touchscreen operation, but the below adjustment features and menu settings can now be changed via touch operation.

RX/TX equalizer level adjustment, meter type (analog white / analog black / bar meter) switching, FFT scope/X-Y scope switching on RTTY decode screen, FFT scope/vector scope switching on PSK decode screen, voice-audio file playback position change. Furthermore, with touchscreen tuning, in addition to the conventional CW tuning operation via longpush, a short push enables tuning using steps set via MULTI/CH, while on bands popular with operation in units of 1kHz, practical touch alignment is possible even in SSB.

Other display system features
  • ● Transmit digital meter enabling display of two kinds of transmit information even during analog meter display
  • ● Audio scope (spectrum scope, oscilloscope) able to be displayed simultaneously with reduced band scope
  • ● Band scope IF filter passband with display
  • ● Change of gradation for waterfall display
  • ● Frequency marker display function (Max. 50)
  • ● Transmit spectrum display (during CENTER MODE)
  • ● SWL display mode
Heavy-duty design delivers transmission performance able to withstand long hours of operation. Highly reliable 100W final-stage amplifier circuit.

The final-stage amplifier device is a Mitsubishi-made MOSFET RD100HHF1(Pch 176.5W) operating in push-pull. A MOSFET RD16HHF1 has been used for the drive amp, and a MOSFET RD06HHF1 for the pre-drive amp. Inter-stage matching and fine-tuning delivers superior transmit IMD even for a 13.8V final circuit, enabling operation with a clean and low-distortion signal.

Heavy-duty design with improved quietness

The unit employs a twin cooling fan system that uses a pair of 80 x 80 mm fans. Using two fans provides sufficient air flow at low rpm, making for superior quietness. The quietness level for the fans when operating has been improved by more than 5dB compared to our conventional models. Furthermore, the use of an aluminum die-cast chassis combined with a large heat sink makes for a heavy-duty design sufficiently capable of withstanding the tough conditions typical of contests or long hours of hard operation.

Built-in high-speed automatic antenna tuner enabling high-speed operation

The antenna tuner is a preset type also operable during receive and covering amateur bands from 1.8MHz~50MHz. High-speed operation and the proven relay method enable rapid QSY through instantaneous band changing. The menu can be used to set an ON/OFF memory for the antenna tuner for each band

Free settings enabled through linear amp control settings menu

A variety of linear amp connections have been taken into account, including self-made ones, and independent settings for various kinds of control at HF/50MHz bands are possible. Possible settings include: linear amp ON/OFF, transmission control (H active, L active), transmission delay ON/OFF, transmission delay time (CW/FSK/PSK) and (SSB/AM/FM), internal relay control, and external ALC threshold voltage adjustment.

Equipped with a TCXO (temperature compensated cr ystal oscillator) requiring no warm-up as standard, high stability of ±0.1ppm has been obtained in a wide temperature range covering from 32ºF~122ºF. External standard signal (10MHz) input is also possible.

FT8 Enthusiasts Urged to Upgrade Now

Tue, 12/11/2018 - 07:45

WSJT-X 2.0 Full Release Now Available

The WSJT-X 2.0 software suite has been released, and developer Joe Taylor, K1JT, is urging FT8 and MSK144 users to upgrade to what will become the new standard, because the FT8 and MSK144 protocols have been enhanced in a way that is notbackward compatible with older versions of the program. That includes any version 1.9 releases.

“The new protocols become the worldwide standards starting on December 10, 2018, and all users should upgrade to WSJT-X 2.0 by January 1, 2019,” Taylor said on the WSJT-X home page. “After that date, only the new FT8 and MSK144 should be used on the air.”

Users are encouraged to read the new Quick Start Guide for WSJT-X. Gary Hinson, ZL2IFB, has released an FT8 Operating Guide.

Fox-1Cliff/AO-95 Receiver Suffers Apparent Failure

Mon, 12/10/2018 - 15:25

The receiver on the newly launched Fox-1Cliff/AO-95 CubeSat seems to have suffered a receiver failure that could render the satellite unusable, AMSAT said over the weekend. Efforts continue by AMSAT Engineering to establish the cause of the problem and determine if a fix is possible. AMSAT Vice President-Engineering Jerry Buxton, N0JY, reported over the weekend that the issue cropped up during efforts to commission Fox-1Cliff/AO-95.

“After a few days of tests, analysis, and discussion, it appears that Fox-1Cliff/AO-95 will not be commissioned as our fourth Fox-1 Amateur Radio satellite,” Buxton said. Commissioning began on December 4, right after the CubeSat’s successful launch a day earlier.

“AMSAT Engineering will continue to evaluate and test Fox-1Cliff/AO-95 for solutions to the anomaly, and your continued help in providing telemetry is appreciated so that we can have data throughout her daily orbits, rather than limited data over our US stations,” Buxton said. “The data, analysis, and testing could lead to a positive solution, but at the very least will be important to AMSAT’s satellite programs in providing information that would help us and others avoid similar situations with future missions.”

In a post to AMSAT-BB, Buxton mentioned one suggestion of employing a high-power station to see if AO-95 could hear its signal, but he added that AMSAT Engineering would not be offering a blow-by-blow narrative of its efforts to restore the satellite to operating condition, “unless it is something of merit or actionable.”

Buxton noted that AMSAT’s resources are limited, and all involved are volunteers. “Most — if not all — of our remaining Fox-1 engineers are also involved in the GOLF-TEE project, so I have asked them to give that first priority with their available volunteer time in order to keep the schedule,” Buxton said. “AO-95 is in orbit now, and we can vary the amount of attention on her as resources allow in order to achieve both goals. If the results of our investigation point to a possibility of recovery, be it partial, full, or some workaround method, we would all like to see her working as much as the rest of you, and that is a driver for this investigation.”

Buxton said he anticipates that AMSAT Engineering will continue to seek the cause of the apparent receiver failure, “until we have results or reach a dead end, because of the inability to take the lid off and look inside AO-95.”

“I will certainly be keeping everyone posted when we have something new to report,” Buxton said.

“Emily Calandrelli, KD8PKR—Science Explorer,” profiled by Jen Glifort, KC1KNL, in the January issue of #QST!

Mon, 12/10/2018 - 12:41

From Emily Calandrelli—host of Xploration Outer Space, correspondent on Bill Nye Saves the World, and graduate of MIT—comes the first novel in a brand-new chapter book series about an eight-year-old girl with a knack for science, math, and solving mysteries with technology.

Ada Lace—third-grade scientist and inventor extraordinaire—has discovered something awful: her neighbor’s beloved Yorkie has been dognapped!

With the assistance of a quirky neighbor named Nina (who is convinced an alien took the doggie) and her ever-growing collection of gadgets, Ada sets out to find the wrongdoer. As their investigation becomes more and more mysterious, Ada and Nina grow closer, proving that opposites do, in fact, attract.

From Emily Calandrelli—host of Xploration Outer Space, correspondent on Bill Nye Saves the World, and graduate of MIT—comes the third novel in a fun illustrated chapter book series about an eight-year-old girl with a knack for science, math, and solving mysteries with technology.

Third grader and inventor extraordinaire Ada Lace likes nothing more than to tinker with mechanics like her robot, George. Her latest project is to fix up a ham radio, something that she could use to contact people on this planet…and beyond. The only problem is that she just can’t get it to work properly.

During a sleepover, Ada’s best friend Nina hears something strange coming from the radio in the middle of the night. A distant voice says, “Release the swarm!” convincing Nina that aliens are about to invade planet Earth.

Could Ada and Nina have stumbled upon something…extraterrestrial?

Finished product WSJT-X 2.0 now available

Mon, 12/10/2018 - 11:54

WSJT-X implements communication protocols or “modes” called FT8, JT4JT9JT65QRA64ISCATMSK144, and WSPR, as well as one called Echo for detecting and measuring your own radio signals reflected from the Moon.  These modes were all designed for making reliable, confirmed QSOs under extreme weak-signal conditions.  

JT4JT9JT65, and QRA64 use nearly identical message structure and source encoding (the efficient compression of standard messages used for minimal QSOs). They use timed 60-second T/R sequences synchronized with UTC.  JT65 and QRA64 were designed for EME (“moonbounce”) on the VHF/UHF bands; JT65 has also proved popular and effective for worldwide QRP communication at HF.  JT9 is optimized for the LF, MF, and HF bands.  It  is about 2 dB more sensitive than JT65 while using less than 10% of the bandwidth.  With either JT9 or JT65, world-wide QSOs are possible with power levels of a few watts and compromise antennas.  JT4 and QRA64 are optimized for EME on the VHF and higher bands, and especially the microwave bands from 2.3 to 24 GHz.  

FT8 is operationally similar but uses T/R cycles only 15 s long.  MSK144 is designed for Meteor Scatter on the VHF bands.  These modes offer enhanced message formats with support for nonstandard callsigns and some popular contests.

As described more fully on its own pageWSPR mode implements a protocol designed for probing potential propagation paths with low-power transmissions.  WSPR is now fully implemented within WSJT-X, including programmable “band-hopping”. 

The current General Availability (GA) release is WSJT-X 2.0.0

The FT8 and MSK144 protocols have been enhanced in a way that is not backward compatible with older program versions.  The new protocols become the world-wide standards starting on December 10, 2018, and all users should upgrade to WSJT-X 2.0 by January 1, 2019.  After that date, only the new FT8 and MSK144 should be used on the air.

NASA releases first sounds ever recorded on Mars Read

Sun, 12/09/2018 - 16:31

Listen to Martian wind blow across NASA’s InSight lander. The spacecraft’s seismometer and air pressure sensor picked up vibrations from 10-15 mph (16-24 kph) winds as they blew across Mars’ Elysium Planitia on Dec. 1, 2018.

The seismometer readings are in the range of human hearing, but are nearly all bass and difficult to hear on laptop speakers and mobile devices. We provide the original audio and a version pitched up by two octaves to make them audible on mobile devices. Playback is suggested on a sound system with a subwoofer or through headphones. Readings from the air pressure sensor have been sped up by a factor of 100 times to make them audible. For full-length uncompressed .wav files, visit NASA.gov/sounds

Fox-1Cliff/AO-95 Commissioning Status

Sun, 12/09/2018 - 07:38

Following the launch of Fox-1Cliff/AO-95, AMSAT Engineering began the commissioning process, with the help of AMSAT Operations, on Tuesday December 4.

Satellite telemetry indicates that the bird is healthy, and I thank all of the stations who have captured and relayed the telemetry that enabled us to monitor and determine the health of the various systems on board.

Fox-1Cliff required an extended period monitoring battery and power levels due to the anomaly and fix that was applied back in February of 2016 during environmental testing, and the result of that is positive.

However, during the next steps of commissioning we discovered an anomaly with her receive capability. After a few days of tests, analysis, and discussion, it appears that Fox-1Cliff/AO-95 will not be commissioned as our fourth Fox-1 amateur radio satellite.

AMSAT Engineering will continue to evaluate and test Fox-1Cliff/AO- 95 for solutions to the anomaly and your continued help in providing telemetry is appreciated so that we can have data throughout her daily orbits rather than limited data over our U.S. stations. The data, analysis, and testing could lead to a positive solution but at the very least will be important to AMSAT’s satellite programs in providing information that would help us and others, as we do freely share our successes and failures, to avoid similar situations with future missions.

I would like to thank all of the AMSAT Fox Engineering volunteers who made Fox-1Cliff possible and continue to build our new satellites, becoming even better as we move forward.

I will provide more information on the anomaly and any determination we make regarding the possible cause or causes as well as information on the possibility of recovery, over time. Please be patient regarding that. Many of you have probably built a project and had to troubleshoot it on your bench, we are in a troubleshooting situation here with the additional challenge of being 600 km away from our bench.

Jerry Buxton, N0JY
AMSAT Vice President of Engineering

2018 QST Antenna Design Competition Winners Announced

Sat, 12/08/2018 - 06:45

ARRL has announced the winners of the 2018 QST Antenna Design Competition.

“Dozens of entries were received, but only three could win,” said QST Editor Steve Ford, WB8IMY.

Requirements for the 2018 QST Antenna Design Competition included an antenna for one or more bands between 2200 meters and 10 meters that could fit within a 30 × 50 foot area and be no taller than 30 feet above ground at any point. 

“In other words, we were seeking designs for LF, MF, or HF antennas for limited-space applications,” Ford explained. “We wanted to see innovative antennas that would allow amateurs to get on the air without the need for towering supports and acres of property. Our winners not only met this challenge, they exceeded it.” The winners: 

  • First Prize ($600): “A High Power 160/80-Meter Transmitting Magnetic Loop Antenna” by Steve Adler, VK5SFA. 
  • Second Prize ($250): “LF/MF Reversible EWE Antennas for Small Lot, Weak Signal Applications” by Michael Sapp, WA3TTS. 
  • Third Prize ($150): “The 3/8-Wavelength Vertical for 20 Meters, a Hidden Gem” by Joe Reisert, W1JR.

Details of all three winning designs will appear in a future issue of QST.

Honorable Mentions

Several entries earned Honorable Mention status. We will be publishing these designs in QST later in the year as well. Honorable Mention recipients were: 

  • “A Magnetic Loop for 80, 40, and 20 Meters” by John Chappell, W3HX
  • “Superior Performance from a Unique HF Vertical Loop” by John Portune, W6NBC
  • “A 630-Meter Mini Antenna that also Works on 160 Meters” by David Day, N1DAY; Ernie Hollingsworth, KC4SIT, and Sid Hendricks, W4IOE
  • “A Multiband Flagpole with Dual Top Hat Wires” by Donald P. Crosby, W1EJM
  • “A Compact, Removable 20-Meter Loaded Vertical Dipole” by Stephen Appleyard, G3PND

Ford expressed his appreciation to all participants and to Joel Hallas, W1ZR, who headed up the judging process. “It took weeks to evaluate the entries, with a lot of that time spent running antenna modeling applications and studying the results,” Ford said.

Next: The 2019 QST Key Design Competition

Hams have been building their own Morse keys since the dawn of Amateur Radio, and some creations have become legend. In 2019, QST is inviting participants to submit their best Morse key/paddle designs in the QST Key Competition. Design styles can include straight key, semiautomatic key (bug), paddle, or sideswiper. The winner in each category will receive $250. Only one entry may be accepted per person or team, and the deadline to submit is June 1, 2019.

Entries must include the actual key (it will be returned following judging) as well as detailed drawings, photos, and a written narrative. Winners will be chosen based on ingenuity of design, ergonomics of operation, and overall craftsmanship. The judges’ decisions are final.

The key must be an independent mechanical device, not an integral part of another device such as an electronic keyer. Keys must be the sole creations of the entrants and not available for sale.

Complete details and entry requirements will appear in the January 2019 edition of QSTThe digital edition is now live.

ARRL Bill Leonard Audio Reporting Award Presented in New York City

Fri, 12/07/2018 - 17:33

The 2017 ARRL Bill Leonard W2SKE Professional Media Award for Audio Reporting was presented in New York on December 6 to the producers and staff of the radio program “The Takeaway.” The program, a joint production of Public Radio International (PRI), WGBH, and WNYC, aired a number of stories about Amateur Radio’s role in supporting disaster relief agencies in Puerto Rico following Hurricane Maria.

ARRL Emergency Preparedness Manager Mike Corey, KI1U, presented the Leonard Award for Audio Reporting to the program’s executive producer, Arwa Gunja, and the show’s staff. “The Takeaway” had interviewed Corey about how radio amateurs were supporting the American Red Cross’s efforts to convey “safety and wellness” messages from the island commonwealth to relatives on the US mainland.

Corey and ARRL CEO Howard Michel, WB2ITX, also toured the WNYC studios, where the program is produced.

Knacksat team request telemetry reports

Fri, 12/07/2018 - 13:34

Tanan Rangseeprom HS1JAN has requested radio amateurs to help with receiving telemetry data from the Knacksat CubeSat that was launched on December 3.

KOn the AMSAT Bulletin Board Tanan writes:

My name is Tanan Rangseeprom my callsign HS1JAN. I am project manager of JAISAT-1 satellite. I am very happy that Thailand, represented by King Mongkut’s University of Technology North Bangkok (KMUT-NB), has successfully launched a Knacksat satellite from the SSO-A mission on
December 3, 2018.

The Knacksat team are very happy to learn that Mike Rupprecht, DK3WN had been the first person to receive the CW signal, however, after that satellite receive ground stations of KMUT-NB HS0AK and ground station of RAST HS0AJ and AMSAT HS members in Thailand have tried to receive the CW signal from the Knacksat satellite but we have not been able to receive any transmission at all. Hence, I am asking for help from all AMSAT members by asking them to please try to receive the CW signal and confirm this online at the following website:

When you provide a signal report online, the Knacksat team will have a very nice QSL card and gift to send in response to thank you for helping us by receiving our signal. In addition, in the future when the satellite is operational, the Knacksat team will be able to provide a packet radio uplink on VHF so that the satellite can respond count number to you with its callsign. So I would like to ask all AMSAT amateur radio operators to please help us in this and to please send any data back to us online website.

Info for amateur radio communities
Call sign: HS0K
CW beacon: 435.635 MHz
comment please send to: knacksat <at> gmail.com.
information of satellite: http://www.knacksat.space/Thank you in advance.
With respect. 73

The K7RA Solar Update

Fri, 12/07/2018 - 10:34

After nine days with no sunspots, sunspot group 2729 emerged on December 5. The sunspot number on that date was 16. Average daily solar flux for the week was 68.9, unchanged from last week. On Thursday, December 6 the appearance of 2729 continued, with a sunspot number of 17 and the sunspot area increasing from 30 to 50 millionths of a solar hemisphere.

Average daily planetary A index rose from 3.3 to 7, while average mid-latitude A index went from 2.1 to 4.9.

Predicted solar flux for the next 45 days is 70 on December 7-8, 69 on December 9, and 68 on December 10 through January 20.

Predicted planetary A index is 10 on December 7, 8 on December 8-9, 5 on December 10-16, 8 on December 17-18, 5 on December 19-27, 8 on December 28, 12 on December 29-30, 10 on December 31, 12 on January 1, 8 on January 2-5, 5 on January 6-12, 8 on January 13-14, and 5 on January 15-20.

Geomagnetic activity forecast for the period December 7, 2018 to January 2, 2019 from F.K. Janda, OK1HH.

Geomagnetic field will be:

Quiet on December 10, 12-15, 19-21, 23

Quiet to unsettled on December 18, 22, 25-27, January 1

Quiet to active on December 9, 11, 16, 24, January 2

Unsettled to active on December 7-8, 17, 30-31

Active to disturbed on December (28-29)

Solar wind will intensify on November 30 and on December 7-9, (10-12, 15-18, 24-27) 28-31, January 1, (2). Parenthesis means lower probability of activity enhancement.”

The current Space Weather Highlights (ftp://ftp.swpc.noaa.gov/pub/warehouse/2018/WeeklyPDF/prf2257.pdf) from NOAA shows updated predictions for smoothed sunspot numbers and solar flux through the end of 2022. As of last month, the predictions ended in 2019.

I’ve been curious to see their prediction for the upcoming solar minimum. If you look on pages 10 and 11 (somewhat obscured by a formatting error) you can see the predicted numbers. The prediction for this month shows a smoothed sunspot number of 10 for December 2018, then declining to 2 in July 2020 through January 2021, then 1 during February 2021 through January 2022, and 0 after that through the end of 2022.

I thought this cycle was supposed to bottom out in 2019 or 2020, but this seems to suggest a disappearance of sunspots in 2022. I wouldn’t bet on it, even though there has been some scary conjecture about a future grand minimum. I am checking some sources and hope to see NOAA clarify this.

Here is an article about observing plasma activity around sunspots to predict space weather: https://bit.ly/2zLmcH4

David Moore sent this article about a view of the solar North Pole: https://bit.ly/2EhQx3K

Mike Schaffer, KA3JAW, observes propagation on the FM broadcast band, and says the winter FM DX season is underway. “On December 2, an FM-DXer near Hamilton, Ontario, Canada reported on the TV/FM Skip Log under the Dxworld website of the reception of five FM stations via Es propagation towards his southwest sector for twenty-one minutes.” The list includes stations in Texas, Louisiana and Kansas, from 1551 to 1612 UTC.

For now, at least, you can see the entries here: http://dxworld.com/tvfmlookback.php

Here is her latest video: https://www.youtube.com/watch?v=Lb6k3dLzPPM

This weekend is the ARRL 10-meter Contest. While solar activity is low enough that it doesn’t support 10-meter propagation very well, there is always the winter sporadic-E activity. See http://www.arrl.org/10-meter for more info.

For more information concerning radio propagation, see the ARRL Technical Information Service at http://arrl.org/propagation-of-rf-signals. For an explanation of numbers used in this bulletin, see http://arrl.org/the-sun-the-earth-the-ionosphere.

An archive of past propagation bulletins is at http://arrl.org/w1aw-bulletins-archive-propagation. More good information and tutorials on propagation are at http://k9la.us/.

Monthly propagation charts between four USA regions and twelve overseas locations are at http://arrl.org/propagation.

Instructions for starting or ending email distribution of ARRL bulletins are at http://arrl.org/bulletins.

Sunspot numbers for November 29 through December 5, 2018 were 0, 0, 0, 0, 0, 0, and 16, with a mean of 2.3. 10.7 cm flux was 67.8, 67.9, 69.4, 69, 68.4, 68.7, and 70.9, with a mean of 68.9. Estimated planetary A indices were 3, 3, 8, 12, 10, 8, and 5, with a mean of 7. Estimated mid-latitude A indices were 2, 2, 4, 9, 9, 5, and 3, with a mean of 4.9.

Introducing the RS-BA1 Version 2 Dualwatch Remote Control Software

Fri, 12/07/2018 - 05:22

The RS-BA1 remote control software gained popularity by allowing Amateur radio operators to operate selected Icom radios from a PC via IP.

The RS-BA1 offers real-time operation with low latency, high-quality audio allowing you to use an Icom radio installed in another room using your home network, or even from a remote location over the Internet.

A new version of this software is now available called RS-BA1 Version 2 which will allow users to take advantage of some of the features of HF radios such as the IC-7610, IC-7851 and IC-7850 including dualwatch operation and dual spectrum scope.

RC-28v.2 IP Remote Control System

The RC-28 IP Remote Control System, allows Radio Amateurs to remotely operate selected Icom amateur transceivers. Incorporating the RS-BA1 Version 2 software, the RC-28v.2 comes complete with remote control USB encoder and will work with the IC-7100, IC-7200, IC-7300, IC-7410, IC-7600 & IC-9100 via USB, and with the IC-7610, IC-7700, IC-7800, IC-7850 & IC-7851 via an ethernet cable.

Dualwatch, Dual Spectrum Scope Control
The dualwatch operation and dual spectrum scopes with the waterfall functions* can be used on your remote PC. MAIN and SUB spectrum scopes can be observed on the RS-BA1 Version 2 at the same time.
* The dualwatch and dual spectrum scope functions are only for the IC-7851, IC-7850 and IC-7610. The spectrum scope functions (single receive) are usable with the IC-7300.

Added Functions
Most functions and modes of your transceiver, including interference rejection functions and IF filter settings, can be controlled using the CI-V commands. The following functions are added to the RS-BA1 Version 2.
• Panel size can be enlarged (Normal or large size selectable)
• Indicator click operation to change the settings
• RIT and ⊿TX functions
• [MUTE] button
• SUB dial

Low Latency, High Quality Audio Over an IP Network
The RS-BA1 Version 2 offers real-time operation with low latency, high quality audio. You can use the transceiver installed in another room using your home network, or even from a remote location over the Internet*.
* A static public IP address or Dynamic DNS is required for the base station (Server) PC, when you configure the remote control system through the Internet.

Note: Depending on your transceiver, some functions or modes cannot be used, or you need to update the transceiver’s firmware.
Please use the latest firmware version of the transceiver.

Supplied items
• CD (including the RS-BA1 instruction manual, the RS-BA1 installer, the USB driver and the USB driver installation guide)
• USB cable (A-B type)
• Installation guides

Note for RS-BA1 Version 1 users: To obtain the new features in the RS-BA1 Version 2, the purchase of the new software package is required.

RC-28 V.2 Specification
  • Minimum system requirements – One transceiver & one PC are connected.
    Operating System: Windows 10/8.1/7 (32/64 bit)
    CPU: 1.8GHz processor or better
    Memory: Windows 10/8.1/7 – 2GB (32 Bit), 4GB (64 Bit)
