Radio: it's not just a hobby, it's a way of life

Current Operating Frequency and Mode

OFF AIR but QRV after dark tonigth

SCHEDULED ACTIVITY: CQ 474.5 kHz CW by 1015z through sunrise most days, WX permitting

Strong signals and quiet band make for a very good session in North America; 9H1BT QRSS QSO with GM3YXM for new DXCC; WH2XZO all-time best to VE7; KP2XX is listening

– Posted in: 630 Meter Daily Reports, 630 Meters

This session was very good and I, unfortunately, did not get to participate much due to a software error that left me only receiving over night.  That’s ok because its still good to see that many stations had very strong nights.

The geomagnetic field bounced around most of the session but was generally quiet.  The Bz was generally stable although solar wind was slightly elevated to moderate levels just above 400 km/s.

Paul, 9H1BT, sent a report of his QRSS QSO with Dave, GM3YXM.  He noted in a follow up email that Dave operated at QRSS10 speeds on the second over for 10 minutes, not 5 as stated in the comment below.  Doing so helped tremendously with QRN on Paul’s end.

Well done guys!  I never would have thought about using tactical call signs to fit the time!  Stefan, DK7FC, also reported a QRSS QSO with Dave, GM3YXM, and Dave reports that tonight is the last chance for a QSO for a few weeks.

VE3OT/B was audible here in Texas during the evening, stronger than heard in the previous week but much weaker than he is normally heard here.

Doug, K4LY / WH2XZO, provided the following comments after his best night ever on the path to the Pacific Northwest:

John, WA3ETD / WG2XKA, had a strong night as well and offered these comments:

Ken, K5DNL / WG2XXM, noted that he decoded 11 and was decoded by 42.  He decoded WH2XCR 18 times, with the best a -19 dB S/N and was decoded by WH2XCR 72 times with the best report of -2 dB S/N.

Neil, W0YSE/7 / WG2XSV, reported that Eric, NO3M / WG2XJM, decoded his signal three times as of 0552z, the best at -21 dB S/N.

WSPR activity was very good with high participation although I did not make a formal check of the numbers on the activity page.  N8OQ was a new or recent addition as was Jim, KP2XX.  I emailed Jim this morning as he was reporting on the old frequency of 503.9 kHz and he reported that he had figured out the frequency later in the evening but had not turned on the upload spots option so the two stations that he decoded remain a mystery.  He indicates that he will be back.

There were no trans-Atlantic or trans-African reports during this session.  UA0SNV was present during this session but had no reports in the WSPRnet database.

Laurence, KL7L / WE2XPQ, operated in a variety of configurations during the session, it seems.  WSPR15 was his primary mode for transmit I think. He also operated in a receive capacity with WE2XPQ and KL7L, providing reports for WI2XBQ and WH2XCR.  There is more to this story but I’ve not sorted it all out as I am writing this report.

In the Pacific, Merv, K9FD/KH6 / WH2XCR, was back on the air again with good reports from stations in the eastern US, including WG2XKA, N8OQ, and WG2XJM as well as ZF1RC.  The path to VK was partially open as noise rages on in the Oceanic Summer.  The path to JA was evidently closed off.

Jim, W5EST, provided the following Friday fun puzzle that is a little more difficult than the previous puzzles he has provided for the blog:


Today’s puzzle clue:  Something appreciated by thoughtful 630m operators.

Hint: Substitution 1 2 3…26 à Letters of alphabet.

   W  –  X + 2Y -2Z = 0

-3W +2X –  Y  + Z  = 1

 2W +  X –  Y          = 1

W(X+Y) – X(Z-1)  = 0

PUZZLE ANSWER: See Section 3 of:  https://www.itu.int/rec/R-REC-BS.561-2-198607-I/en
