First FT8 Roundup is a Huge Hit
By qrznow
The first FT8 Roundup over the December 1 – 2 weekend attracted some 1,300 logs from those taking advantage of the ever-more-popular digital protocol. This, despite its having been announced on fairly short notice and with other contests such as the ARRL 160-Meter Contest under way on the same weekend. More than 400 logs were from US radio amateurs in the 48 contiguous states, plus the District of Columbia. Overall, some 131,200 contacts were recorded. Participants from 91 countries submitted logs, testifying to the fact that FT8 is not just an US phenomenon.
“The FT8 Roundup was the last shakedown for the WSJT-X 2.0-rc5 beta software,” said well-known RTTY contesting enthusiast and expert Don Hill, AA5AU, an FT8 Roundup cosponsor with Ed Muns, W0YK. “It performed with no major complications.” The general availability release of WSJT-X 2.0 is now out, and it’s not backward compatible with WSJT-X 1.9 or earlier versions. Developer Joe Taylor, K1JT, has urged users to upgrade by January 1 to what now is new world standard.
Muns, who’s NCJ “Digital Contesting” contributing editor, said FT8 Roundup participation compared favorably with that for the ARRL RTTY Roundup, which has averaged around 1,700 logs in recent years.
“Don and I expected the contest to be popular,” Muns said, “but the participation far exceeded our expectations. I think it bodes well for future FT8 contesting. Don and I are pretty bullish about continuing the FT8 Roundup on the first full weekend of December each year.” Nonetheless, Muns said he doesn’t believe FT8 will “really take off” and displace RTTY until the contact rate can be significantly increased through parallel QSO techniques.
Hill agreed on the event’s popularity. “I have to say it was a huge success,” he said. “Ed and I never dreamed it would be this popular. It didn’t make sense to continue the Ten-Meter RTTY Contest during this part of the sunspot cycle. Replacing it with an all-FT8 HF contest was the logical choice.” Hill and Muns also co-sponsor the Ten-Meter RTTY Contest.
Hill told ARRL that final results of the inaugural FT8 Roundup should be out in a few days. “After the New Year, we hope to have downloadable online certificates available to all participants. We will definitely do it again next year,” he said.
The 2019 ARRL RTTY Roundup will permit the use of FT8.

Broadcasters Intruding on Exclusive Amateur Radio Frequencies
By qrznow
The International Amateur Radio Union Region 1 (IARU-R1) Monitoring System (IARUMS) reports that Radio Hargeisa in Somaliland has returned to 7,120 kHz after a break of several weeks, while Radio Eritrea has been reported on 7,140 and 7,180 kHz. Radio Sudan has been transmitting on 7,205 kHz with excessive splatter, IARUMS said. German telecommunications authorities have filed official complaints.
IARUMS has also reported digital signals attributed to the Israeli Navy on 7,107 and 7,150 kHz. In addition, a Russian military F1B signal was observed in mid-November on 7,179 kHz. A Russian over-the-horizon radar has returned to 20 meters on 14,335 – 14,348 kHz. It was monitored on November 22. Earlier this fall, IARUMS reported digital signals from the Polish military daily on 7,001.8 kHz where Amateur Radio has a worldwide primary allocation. Telecommunications officials in Germany filed a complaint.
IARUMS has received reports of short “beeps” exactly 1 second apart, as well as frequency hopping between 10,108 and 10,115 kHz and 18,834 and 18,899 kHz. The signals are believed to emanate from a site near Chicago associated with an FCC-licensed Experimental operation involved with low-latency exchange trading on HF (see “Experiments Look to Leverage Low-Latency HF to Shave Microseconds off Trade Times”). Although Amateur Radio is secondary on 30 and 17 meters, Experimental licenses may not interfere with Amateur Radio operations.

New Regions Brighten the Sun’s Face: Solar Storm Forecast 12-12-2018
By qrznow
“The fast solar wind we have been enjoying over the past week from an extended coronal hole is finally beginning to wane. We will likely remain at unsettled conditions over the next few days and return to quieter conditions by the end of the week. We also have 3 new bright active regions on the Earth facing Sun that are boosting solar flux for amateur and shortwave radio operators and emergency responders. This means radio propagation is back to marginal levels on Earth’s day side and will likely remain that way over the next week. See the details of these bright regions, catch up on aurora photos from the recent solar storms, and see what else our Sun has in store this week!”

Jordan’s First CubeSat, JY1Sat, is Designated as JO-97
By qrznow
JY1Sat, launched on December 3 from Vandenberg Air Force Base in California as part of the SpaceX SSO-A: SmallSat Express launch, has been designated as Jordan OSCAR 97 (JO-97). The 1U CubeSat is a project of the Crown Prince Foundation of Jordan. Telemetry has been received and decoded around the world since the launch.
The spacecraft’s name recalls the Amateur Radio call sign of Jordan’s late King Hussein, JY1. JO-97 carries a 435/145 MHz SSB/CW inverting Amateur Radio transponder and a Slow-Scan Digital Video (SSDV) system to transmit stored images.
The telemetry downlink is on 145.840 MHz, the transponder downlink passband is 145.855 – 145.875 MHz, with an inverting uplink on 435.100 – 435.120 MHz. — Thanks to AMSAT
