Band conditions appear to be very good for many in spite of the recent geomagnetic storming. It seems Kp levels are beginning to stabilize over multiple reporting periods in spite of continued solar wind in excess of 500 km/s and a south-pointing Bz.
John, WA3ETD / WG2XKA, in Vermont provided the following comments on the session:
Doug, K4LY / WH2XZO, in South Carolina sent this report:
Doug mentioned low power operation at his station. He has experienced multiple failures of his Astron power supply over the last few months. It seems that while his particular model has plenty of capacity to run his PA, it is not able to provide that capacity at high duty cycles. While 30% transmit cycle of WSPR is hardly high duty cycle, perhaps less expensive and lower quality filter capacitors are being used that result in these failures. Its unfortunate as I have had high hopes that Astron would provide an inexpensive alternative to some of the other 24-28v power supplies on the market.
Neil, W0YSE/7 / WG2XSV, in Vancouver, Washington, sent the following note. Neil also mentions power supply issues but fortunately he found a solution that yielded good results.
WSPR activity was very good, with 74 MF WSPR stations observed at 0245z. Regional and continental WSPR breakdowns follow:
There were no reports from the trans-African path. UA0SNV and UA4WPF were present during the session but had no reports in the WSPRnet database. I am hopeful about UA4WPF as he is closer to western Europe than UA0SNV but RF still has to cross quite a bit of land. Its my hopes that on the right night he will have similar success as UA0SNV has had from much further away.
John, WA3ETD / WG2XKA, was reported by Clemens, DL4RAJ, for the sole trans-Atlantic report for the session.
Eden, ZF1EJ, and Roger, ZF1RC, provided reports from the Caribbean.
Laurence, KL7L / WE2XPQ, was seriously impacted by the most recent geomagnetic activity but he was decoded by VE7BDQ and decoded WH2XCR during this session.
At tropical latitudes, Merv, K9FD/KH6 / WH2XCR, experienced much better propagation during the session:
Phil, VK3ELV, received the following reports from early in the session in Oceania:
Additional statistics, comments, information, and anecdotes:
Ken, K5DNL / WG2XXM, reports that he decoded ten stations, and was decoded by 42 unique stations during the session.
Jim, W5EST, provided a correction to some information from a previous commentary as well as some “Friday fun” in the form of a puzzle:
“EXTENDED MODE TABLE CORRECTIONS & PUZZLE
Thanks to Neil WG2XSV W0YSE for pointing out a couple of corrections for the Feb. 15 Extended Mode Table. John has entered the corrections to the Feb. 15 blog itself.
Correction 1:JT9 does not have a database that I know of. PSK Reporter does have a JT9 spotting service. PSK Reporter is a spotting service that includes selectable JT9 on the map link. No database appears there that I’ve found. A clickable geographic map does show information about recent stations spotted, see this link: http://pskreporter.info/pskmap.html . You can see stats and reporter call signs at: https://www.pskreporter.info/cgi-bin/pskstats.pl
To check if your station’s WSJT-X feeds JT9 data to PSK Reporter, go to WSJT-X menu item File\Settings\Reporting. In mid-screen “Network Services” make sure the checkbox is checked: “Enable PSK Reporter Spotting.” When you are receiving JT9, check the PSK Reporter web site http://pskreporter.info/pskmap.html to make sure the upload is actually working. If not, e-mail and tell us the problem and any fix you know of. We’ll also try to find out more because there’s numerical URL information near that checkbox that may be relevant.
Correction 2: Hellschrieber is NON linear, like CW. The Table is corrected to say “Yes” nonlinear is ok. Regarding Opera, I’ve changed the entry to “Yes?” until we find out differently.
Clue: Some of many things radio amateurs would like. Answer with three numbers X, Y, Z.
X – Y + 2 = 160
3X +106 – 4Z = 80
-2X + 3Y -116 = 40″
