Most of North America was quiet and “in the clear” during this session although storms were present in the Atlantic off of the southeastern coast. Lightning crashes were reported in the West, presumably from Pacific storms off of the coast of Mexico. Japan and Europe were mostly lightning free but Australia is experiencing storms ranging from the southeastern coastal region through the north central region.
Geomagnetic conditions are quiet. The Bz is pointing to the North this morning and solar wind velocities are averaging near 400 km/s. DST values are very stable, remaining close to the centerline.
Domestic propagation was good with low to moderate noise levels, even early in the session in North America but QSB remains a player. East coast trans-Atlantic openings were much less prolific than the previous session with lower latitude signals from southern Europe comprising those reports. There were two stations in the Northwest that experienced polar openings to Scandinavia and this may be the first time since Decemeber 6, 2016 that we have seen this type of behavior on paths to Europe from North America. The path between the West coast and Alaska provided some excitement during the late evening. Trans-Pacific openings to North America remain poor but the path to Japan from a number of locations continues to show results. Daytime openings around North America were reported to be pretty good.
Reverse beacon network reports follow:
David, G0MRF, is operational from his remote site using JT9 and seeking North American stations. He began operation during this session around 2330z and continued until around 0130z. No North American QSO’s were completed but a number of stations were listening. David plans on being active into the New Year and he submitted the following initial summary with a few additional details:
The remote station is now operating nicely from IO91FR. Although there have been a few ‘issues’ to resolve. After 8 hours on site, we now have an IC7300 connected to a Windows PC running Teamviewer 13 and WSJT-X. The Icom feeds a class C amp which can be adjusted up to 75 Watts RF output. Antenna is 250ft of wire configured as an inverted L, 110ft high at the tower with the 140ft topload section 60ft high at the far end.
As the first night WSPR reports show, it transmits very well. 81 stations reporting the signal with 6 in The USA.
a) The ICOM, even with a preamp, isn’t a great receiver. There is some degradation, possibly from 2 x 500kW MW transmitters about 40 miles away and possibly from the rather noisy output from the 7300’s receiver on 630m. It’s not ‘bad’ – It has received A1AA and N1BUG, but when every last dB counts, I need something better. The solution, which isn’t pretty, was to feed audio from a much better RX antenna from a different site and decode that at home.
b) The second issue relates to the 2 instances of WSJT running on different machines. The timing is a little tricky and it’s taken a few hours to learn how to drive it all.
The Way Forward?
Seeing multiple reports from the USA on the first night was really rewarding, but transmitting CQ on JT9 on the second night and hoping for the best probably isn’t going to work very well. Thank you to everyone who was listening. So, I’m open to suggestions here, but shall we use WSPR for its real purpose. – As a propagation indicator. I will switch my attention from Europe to NA at 23.00 for about 60 – 90 mins. If propagation is good I can call around dial +1240 and liase via the chat.
If propagation is not good, I suggest after 60 – 90 mins I switch to WSPR and if anyone with a TX spots my signal overnight at -26dB or better…..then give me a call / text free of charge using WhatsApp. From the USA, it’s (011) 44 7958502540“
Stefan, DK7FC, reported the QRSS CW message of Alberto, EA4GHB, from his receiver in the city which, no surprise, he indicates is noisier than his remote receive site in the forest. Even so, the signal is very strong in Germany:
Jim, W5EST, submitted the following screen capture of his WSJTx console showing JT9 activity observed at his station in Little Rock, Arkansas (click to enlarge):
The following stations provided reports of their two-way QSO’s and/or any additional activity that might have occurred during this session (this is not necessarily a complete list – only what was reported!):
Neil, W0YSE, reported a very strong session of CW and JT9 with a number of stations on some unlikely paths. He submitted the following detailed comments and statistics:
“I had a JT9 Q with Roger, VE7VV around 03z. Then I put up a CW beacon on 474.7 kHz so that it would show up on the lower end of the WSJT-X waterfall. I got reports (via chat) from Robert, KR7O of RST 459 to 579. Then Clint, KA7OEI in Utah reported that I was 25 dB above the noise in a 0.17 Hz bandwidth. My EIRP was around 2 watts.
I went on to have a JT9 QSO with Clint after which I was reading that VE7VV was saying (on chat) that he was seeing Laurence, KL7L on his JT9 screen. A bit later I was able to have a nice JT9 Q with Laurence. His last message to me in “free msg” was “TNX NEIL CW S” which I took to mean that he was copying me at CW strength. So, I switched over to CW near our JT9 frequency and called Laurence while he scrambled to grab his key and figure out how to switch over from JT9 to CW mode. Finally I heard Laurence calling me and we completed a CW Q. Laurence was a 539 to 549, and he said I was 449 to 549. This was a “first” for both of us. Adrenalin was flowing…it would be hard to get to sleep now…” Neil also included this chat transcript.
Roger, VE7VV, reported “Conditions were better tonite. JT9 QSO’s with W0YSE, KA7OEI, KL7L.“
John, WA3ETD, completed JT9 QSO’s with KC4SIT, NC8W, K2BLA, K3MF, K5DNL, ZF1EJ and W3XY. John added that his DXCC total is now at three and a number of new stations were transmitting for the first time last night with WSPR. John also reported that K9SLQ was heard through the day.
Al, K2BLA, reported that he “Worked K3MF last nite; a new one for me. Also worked WA3ETD and WB4WJM last nite. This AM a big JT-9 meeting; worked KC4SIT, ZF1EJ, W3XY, KC3OL, VE3CIQ, and K5DNL. WSPR: Heard by 47 including YV7MAE. Need to get him and other SA stations on JT-9 to help us here in the extreme Southeast work new grids and DXCC entities. EU is rough from here but heard 19 on WSPR including G8HUH.“
Ted, KC3OL, reported JT9 QSO’s with N9N (W9XA), ZF1EJ, and K3MF.
Wayde, K3MF, completed JT9 QSO’s with WA3ETD, K5DNL and KC3OL. He completed a CW QSO with K8RYU. Wayde also reported W7IUV through the night which he indicates was the longest report he has provided so far.
Joe, K9MRI, completed JT9 QSO’s with WB4JWM and a CW QSO with K8RYU.
Tom, WB4JWM, completed a JT9 QSO with K9MRI and am FT8 QSO with K9KFR.
Clint, KA7OEI, reported a JT9 QSO with K9KFR. He also reported W0YSE’s CW 25 dB out of the noise and noted that there was quite a bit of QSB on signals. He was not hearing much to the East.
Ken, K5DNL, completed JT9 QSO’s with WA3ETD, K3MF, WB4JWM, KC3OL and K2BLA. Using WSPR overnight, Ken reported 23 stations and he received reports from 88 unique stations including KL7L, YV7MAE and ten Canadian stations.
Roger, VK4YB, reported “Very poor propagation at this time. In the small gaps between lightning the noise level is very low even on the verticals which are normally 10dB worse than the long wires. I think that just means there is high absorption locally. The Northern hemisphere seems to be free of this.” Roger received JT9 reports from KL7L between 1204z and 1214z at -24 dB S/N to -26 dB S/N.
Hideo, JH3XCU, reported first time reception of VK4YB’s CQ’s using JT9:
Robert, KR7O, reported that “W7IUV copied throughout the day with a few other stations popping in/out also. W0YSE 459-579 last night on CW. Lightning crashes and high noise again. Only a few TC decodes. Another good night to KL7L (51/-8) on WSPR and up to -16 on JT9. KH6 path attenuated with K9FD (66/-14).”
Keith, K0KE, expressed surprise of reports of his signal a VE6JY in early afternoon in Colorado. He added that he was hearing W7IUV and KA7OEI for hours through daylight and notes that he has worked seventeen states using JT9 but has heard no one from New England yet. He submitted the follow WSPR data receptions for others and of his signal from midday:
Larry, W7IUV, operated WSPR overnight, receiving polar reports from Europe, and submitted the following comments and statistics:
“Had a few decodes of VK4YB, and was decoded by him a few times. Also by LA2XPA and 70 others. Had 7 spots from LA2XPA ranging from -21 to -27, JT9 workable levels…..”
Bill, AA2UK, received transcontinental signals from W7IUV during this session for over an hour. What is curious is that Bill was listening with a 6-meter Moxon antenna which probably gave him a bit of a S/N boost on an otherwise quiet night. This behavior was similar to my early reports in 2010 using a Comet GP3 VHF/UHF antenna at 45 foot height. Bill submitted the following report details:
Activity at KB5NJD was mostly limited to listening. I made a few calls on 474.5 kHz using CW and may have had a caller but the signal was very light and one of my main receive antennas is water logged so it was inoperative. I will be addressing that situation today. W5EST reported me at RST 599 around 0130z on a very short hop between Dallas and Little Rock. This morning I called CQ briefly on 474.5 kHz CW, receiving a reverse beacon report from WZ7I at decent levels. Time was short so I did not hang around long.
