3Y0J Bouvet 2023 [ CANCELED ]

Sun, 06/13/2021 - 12:18

“To the global DX community. We regret to inform you of the following news.The global pandemic has impacted the expedition charter vessel business very hard; this includes the venerable RV Braveheart which has provided outstanding safety and service to many DXpeditions.

As you know, we had signed a contract with Braveheart for 3Y0J.Today, we were informed that Braveheart will be sold. As a result, Nigel Jolly will no longer be associated with the ship, our contract with the ship has been cancelled and our deposit will be refunded. This is a very disappointing development to all involved.At this time, we are cancelling the 3Y0J Dxpedition.

We have ceased accepting donations and we will begin refunding 100% of the donations using the same method they were received, i.e., PayPal, cash or check. This process will take several weeks to sort out, so please be patient.We wish to thank our team for putting their trust in us. We wish to thank all of the donors and sponsors that gave generously to this project. We will continue to research other ships and possibly find another suitable vessel for a future project.73,

The K7RA Solar Update

Fri, 06/11/2021 - 11:21

Tad Cook, K7RA, Seattle, reports: Sunspot activity has shown steady but modest increases over the past 3 weeks, with average daily sunspot weekly averages rising from 24.9 to 28 to 34.9. Oddly, average daily solar flux for the same 3 weeks was 77.8, 77.8, and 77.7, remarkably unchanged week after week.

Average daily planetary A index went from 6.1 last week to 5.9 in this week’s report, and middle latitude A index went from 6.3 to 6.9.

Predicted solar flux over the next month is 75 on June 11 – 20; 80 on June 13 – 17; 75 then 80; 82 and 77 on June 21 – 23; 76 on June 24 – July 5; 74, 74, and 75 on July 6 – 8; 74 on July 9 – 14, and 75 on June 16 – 17.

Predicted planetary A index is 5 on June 11 – 13; 8 on June 14 – 15; 20 and 18 on June 16 – 17; 5 on June 18 – 25; 7 on June 26; 5 on June 27 – July 4; 15, 10, and 8 on July 5 – 7; 5 on July 8 – 12; 20 and 8 on July 13 – 14, and 5 after mid-July.

Here’s the geomagnetic activity forecast for June 11 – July 7 from F.K. Janda, OK1HH, who has been compiling these reports since January 1978.

The geomagnetic field will be:

  • quiet on June 12 – 13, 18 – 20, 24, 27 – 28, July 1 – 2
  • quiet to unsettled on June 11, 15, 17, 29 – 30, July 6
  • quiet to active on June 11, 14, 17, 21, 25 – 26, July 3 – 4
  • unsettled to active June 16, 22 – 23, July 5
  • active to disturbed – none
  • solar wind will intensify on June (11 – 13,) 17 ( – 18,) (22 – 24, 29,) July (2,) 4 – 5

* Parenthesis means lower probability of activity enhancement.

Checking the STEREO mission every day we see more activity in store over the sun’s eastern horizon. You will recognize it as intense white splotches

Watching 6 meters on pskreporter.info on June 10 at 0550 UTC, I noticed an odd late-night opening in western North America, showing many long-distance FT8 contacts. Some had positive signal reports, i.e., above the noise. This is notable because most reports on this website are negative (i.e., below the noise level), but one stood out. It was a 609-mile +5 dB report from K6VVP in San Francisco (CM87rs) to WA7DUH in Eastern Washington (DN06hg). Later I saw a 727-mile report from KA9UVY in Illinois (EM58mk) to N3OUC in Pennsylvania (FN20fm) at 0632 UTC with the signal at only –10 dB. Both reports showed the frequency as 50.314 MHz.

Of course, when FT8 signal reports are above zero, the same path should be viable for other modes, such as CW and SSB.

Michael May, WA8VLC/7 in Salem, Oregon wrote:

“It’s been 2 weeks since an update, and, aside from some FT8, SSB, and CW DX and stateside on 6 meters — including Trinidad and Hawaii on 50.313 and some midwest and eastern US and Canada on 6 meters FT8, SSB, and CW mostly last week. Still the most interesting and weird things occurred on 10 meters — both ham and non-ham activity.

“On May 31 on 29.62 MHz FM, I found the KQ2H repeater in New York in for several hours, and I spent most of the day talking to several hams all over the eastern and southeastern US on this repeater, which never faded for the entire day.

“I actually took an hour break and went to 10 SSB and worked French Guiana, and when I came back, the 29.62 repeater was still 20 dB over S-9. This was simply the best 10 meter activity I have seen in years on FM.

“On June 9 at 0330 – 0355 UTC, another Salem ham, K6FIB, and I both heard several non-ham French-speaking stations coming through my 10-meter remote base on 29.6 FM, speaking to another much weaker non-ham station for 15 minutes.

“At this time I zeroed my four-element 10 meter Yagi to ~195°, which put them somewhere in the Eastern Pacific, but where?

“After some searching around on other 10 meter frequencies, I heard similar voices on 28.700 FM speaking a similar French dialect but this time two of them were readable. One appeared to be a base station that was much stronger, chatting with a much weaker, but readable, station.

“After listening to the 28.700 FM transmission for a half-hour, the strong station identified as ‘Pape’ete radio’ at 0355 UTC, and several minutes later they slowly faded out.

“This would put these transmissions in French Polynesia, but I found it interesting that no hams were on FM from that region on 10 meters.

“In the past 30 years, I have never heard a ham station from these locations on FM, so that was not surprising at all; however, there were South Pacific hams in ZL on 28.074 FT8 and 10 meter CW at the same time.

“These stations, aside from French speaking, sounded like standard FM Land Mobile stations you’d hear on VHF. But I am now discovering more of these odd non-ham signals between 26 and 39 MHz from non-US locations.”

[Great investigative work, Michael! Readers may recall in ARLP022 Michael reported hearing North Korean squid fishermen on 10-meter FM. Quite a “catch.” — K7RA]

“May 30 and 31 good here. On May 31 had JA8JEP (QN03) in at –14 dB 2238z 50.323 MHz FT8.

“June 5, XE2X spotted 9K2OD on 50.323 MHz FT8 at 1335z. That is remarkable.

Check out this video of the huge antenna array built for the Soviet Union’s former over the horizon HF radar, the so-called “Russian Woodpecker,” a constant annoyance for HF operators a few decades ago. Quite impressive!

Website for the Apache Point Observatory in Sunspot, New Mexico.

Here’s the latest video from the Space Weather Woman, Tamitha Skov, WX6SWW.

Sunspot numbers for June 3 – 9 were 28, 30, 30, 42, 53, 34, and 27, with a mean of 34.9. The 10.7-centimeter flux was 75.5, 77.1, 74.4, 77.4, 80.8, 79.9, and 78.6, with a mean of 77.7. Estimated planetary A indices were 6, 5, 4, 5, 12, 5, and 4, with a mean of 5.9. Middle latitude A index was 8, 4, 4, 6, 15, 7, and 4, with a mean of 6.9.

WSJT-X version 2.4.0 Now Generally Available, Version 2.5.0 on the Horizon

Thu, 06/10/2021 - 09:09

WSJT-X version 2.4.0 now is available in general release. According to co-developer Joe Taylor, K1JT, WSJT-X version 2.4.0, includes a new digital mode, Q65. This protocol is designed for two-way contacts over especially difficult propagation paths, including ionospheric scatter, troposcatter, rain scatter, TEP, EME, and other types of fast-fading signals.

“On paths with Doppler spread more than a few Hertz, the weak-signal performance of Q65 is the best among all WSJT-X modes,” the Quick Start Guide asserts.

WSJT-X version 2.5.0-rc1 (beta) version has been released. According to the Release Notes, version 2.5.0 “the Q65 decoder has been enhanced to measure and compensate for linear frequency drift in Q65 signals.”

Q65 uses 65-tone frequency-shift keying and builds on the demonstrated weak-signal strengths of QRA64, a mode introduced to WSJT-X in 2016. Q65 offers user message and sequencing identical to that in FST4, FT4, FT8, and MSK144. It includes a unique tone for time and frequency synchronization. As with JT65, this “sync tone” is readily visible on the waterfall spectral display. In addition, Q65 provides a sensitive “sync curve” near the bottom of the waterfall window.

Testing showed that Q65 will enable stations with a modest Yagi and 100 W or more and to work one another on 6 meters at distances up to ~2000 kilometers on most days of the year, in dead band conditions.

“An excellent example of targeted uses of Q65 is ionospheric scatter on the 6-meter band,” the documentation states. “Extensive tests on the 1,150-kilometer path between K1JT and K9AN have shown that with 300 W power output, nearly every Q65-30A transmission is copied correctly by the other station.” The 30A refers to the transmit-receive period and spacing width.

For the complete announcement and to download the latest version, visit the WSJT-X website.

International Space Station to be in Cross-Band Repeater Mode for Field Day

Thu, 06/10/2021 - 07:14

The Amateur Radio on the International Space Station (ARISS) cross-band repeater will be available for ARRL Field Day, June 26 – 27. Contacts will count toward Field Day bonus points as satellite contacts and Field Day contacts.

Field Day rules limit stations to one contact on any single-channel FM satellite. Note that contacts made during Field Day by ISS crew would only count for contact credit, but not for satellite bonus points. ISS cross-band repeater contacts are also valid AMSAT Field Day satellite contacts.

The ARISS cross-band repeater uplink is 145.990 MHz (67 Hz tone), with a downlink of 437.800 MHz.

ARISS suggests that those unfamiliar with the ISS repeater may want to practice with it prior to Field Day. ARISS had planned to switch modes to the Automatic Packet Reporting System (APRS) during the second week of June, but this won’t happen until after the first ARISS school contact following ARRL Field Day.

The ARISS ham station will be off-air during spacewalks on June 16 and June 20. — Thanks to ARISS

ISS repeater remaining on until after Field Day

Tue, 06/08/2021 - 06:04

The International Space Station crossband FM repeater should remain active until after the Field Day weekend of June 26-27.

Amateur Radio on the International Space Station (ARISS) has decided to keep its ARISS InterOperable Radio System (IORS) in crossband repeater mode until after ARRL Field Day ends. The IORS ham station is located in the Columbus Module of the International Space Station.

ARRL HQ Contest Program Manager Paul Bourque, N1SFE, has confirmed that successful radio contacts made through the ARISS IORS, in crossband repeater mode, will count for an ARRL Field Day QSO point, but also for Field Day bonus points! Another fun opportunity for points. Don’t forget the rule limiting stations to 1 QSO per any single channel FM satellite.

On-orbit astronauts always have very busy schedules, but if a voice contact were to be made with them, it would count for QSO credit but not for satellite bonus points. Only an ARISS crossband repeater QSO qualifies for the bonus. Crossband repeater contacts are also valid for AMSAT Field Day for satellite operations, held concurrently with the ARRL event.

Frequencies for ARISS crossband repeater operation are as follows: 145.990 MHz up, 67 Hz tone and 437.800 MHz down. If you haven’t used the ISS repeater yet, be sure to practice with it before Field Day (June 26-27, 2021). These contacts can be tricky, but hams can practice right now…can you do it?

ARISS had planned a mode switch to APRS packet during the second week of June. Now, ARISS is targeting the switch by the astronauts to packet after the first ARISS school contact following ARRL Field Day. In more news for ARISS supporters: the astronauts will power down the ARISS radio station during USA spacewalks on June 16 and June 20, 2021.

E-Coder 2 Controller

Mon, 06/07/2021 - 06:06

The E-Coder 2 panel was designed to control Expert Electronics SDR devices with a focus on remote operation. It has a high quality low latency sound card on board to solve the common SDR issue with latency/delay of monitor audio. This  especially important to CW operators operation remote. In addition it has the same wide range of functionality as the E-Coder 2, which makes it the perfect controller for serious DX and contesting.

The E-Coder 2 has a VFO optical sensor that produce 1024 pulses per revolution compared to 200 pulses per revolution for the standard E-Coder EP. This allowed for more precise fine-tuning when using maximum zoom in the spectrum.

In the Panel menu, you can see the settings of the E-Coder 2 control panel. In the drop-down Device menu, you can select the type of the connected control panel. In the meantime, only one type is available – E-Coder. Note! If one E-Coder 2 panel is connected to the transceiver, in the Panel menu displayed one E-Coder tab, if several E-Coder panels are connected to the transceiver, in the Panel menu displayed a several tabs E-Coder #1, E-Coder #2 etc. with identical settings for each panel.

Main:

  • AGC Up/Down – AGC type switching
  • Band Up/Down – band switching
  • Filter Up/Down – receiver’s filter switching
  • Mode Up/Down – mode switching
  • MOX – enable/disable manually operated transmit mode
  • PA – enable/disable power amplifier
  • Preamp Up/Down – preamp or attenuator level switching
  • Power ON/OFF – transceiver’s power on/off
  • RX ANT – enable/disable receive antenna
  • Step Up/Down – change the tuning step
  • Tone – enable/disable tone signal in TX mode
  • WF – enable/disable Wide Filter. Filter for all Nyquist zone. If in the Device menu settings, you set Auto enable checkbox, then you don’t need this function on the panel
  • Zoom In/Out – spectrum zoom modes switching

VFO/RX2:

  • A>B – assign the frequency from heterodyne VFO A to heterodyne VFO B
  • B>A – assign the frequency from heterodyne VFO B to heterodyne VFO A
  • B<>A – frequency exchange between VFO A and VFO B
  • Change VFO A/VFO B – switching between VFO A and VFO B
  • IF as RIT – tune the RIT offset by moving the filter over the panorama
  • LOCK – lock the frequency tuning

SDR Receiver for IOS version 1.2.1 has been released

Sat, 06/05/2021 - 07:34

SDR Receiver demodulates and plays AM and FM signals received by an RTL-SDR, Airspy HF+ or SDRplay radio. Requires a radio and a host computer  with SDR Receiver. SDR Receiver streams data from an rtl_tcp, hfp_tcp or rsp_tcp server application which are free and open source applications. The appropriate server application must be installed on the host computer and configured for the attached radio.

SDR Receiver is a Software Defined Radio (SDR) that processes, demodulates and plays AM, narrowband FM and wideband FM signals. Listen to communications from aircraft (AM), amateur repeaters and VHF handhelds, police and fire, NOAA weather reports (narrowband FM) and commercial broadcasts (wideband FM).

  • Easily entered and managed lists of stations simplify station selection.
  •  Export and import lists of stations in CSV or TSV format.
  •  Adjustable squelch that works for both AM and FM signals.
  •  Adjustable LNA gain (for RTL-SDR and SDRplay radios).
  •  Adjustable audio high pass and low pass filters.
  •  Selectable IQ Offset eliminates DC errors.
  •  Signal strength indicator that shows power level in the signal passband.
  •  Multiple sampling rates to accommodate different network bandwidths.
  •  Selectable 8-bit or 16-bit sample size streaming from Airspy HF+ and SDRplay radios.
  •  Custom URLs enable another application on the same device to set the station and start streaming.
  •  Supports VoiceOver.

SDR Receiver processes signals that are streamed over the network from a host computer (Mac, PC or Raspberry Pi) that is attached by USB bus to an RTL-SDR, Airspy HF+ or SDRplay radio. An rtl_tcp server or equivalent application running on the host computer receives baseband IQ data from the radio and streams the sampled signals over the network to the iPhone or iPad running SDR Receiver.

Requires an RTL-SDR, Airspy HF+ or SDRplay radio and a host computer which are not provided with the application. Support for 192 ksps and 384 ksps Airspy HF+ sampling rates requires Airspy HF+ firmware version R3.0.7 or later, and hfp_tcp version v.1.2.117 or later.

Version 1.2.1

  • Improved AM demodulator
  • IQ Offset control eliminates DC error and distortion on AM

SDR Receiver for IOS is available for download for $9.99 from the Apple App Store.
