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

Current Operating Frequency and Mode

OFF AIR but will be QRV on CW somewhere between 472.5 kHz and 475 kHz after dark

SCHEDULED ACTIVITY: CQ 474.5 kHz CW by 1030z through sunrise most days, WX permitting

WH2XCR reports JA1PKG once again, ZF1EJ reports WD2XSH/15 for the first time, Nice propagation and strong signals, and PY2VM may be gearing up for 630-meter WSPR

– Posted in: 630 Meter Daily Reports, 630 Meters

Good afternoon.  The band yielded very strong signals through the session with many stations audible with receive stations reporting persistent single digit positive and negative S/N values.  The geomagnetic field was quiet through the session but that may be a precursor to the next glancing blow from a recent CME.  The Kyoto DST appears to have returned to zero during the session.

Quiet conditions in Kyoto or calm before the storm?

 

Daytime conditions were fair from here in Texas with sporadic reports to the east central US and upper Midwest.

XIQ daytime 111215

WG2XIQ Daytime WSPR activity

 

WSPR activity was strong worldwide but I failed to take the band census last evening so I do not have a hard number of stations on 630-meter WSPR to report.  The worldwide break down is as follows:

 

NA 111315

North American 24-hour WSPR activity

 

EU 111315

European 24-hour WSPR activity

 

JA 111315

Japanese 24-hour WSPR activity

 

VK 111315

Australian 24-hour WSPR activity

 

In the Atlantic, Ed, VP9GE, continues to supply reports for New England.

In the Caribbean, Eden, ZF1EJ, and Roger, ZF1RC, continue to be active.  Eden reported WD2XSH/15 in Arkansas for the first time during this session.

 

ZF1EJ 111315

ZF1EJ 24-hour WSPR activity

 

ZF1RC 111315

ZF1RC 24-hour WSPR activity

 

There is no trans-Atlantic or trans-Africa to report through this session.  There was some talk that Michel, FR5ZX, might be trying out OPERA but I have seen no data to confirm or deny whether this is true.

In Alaska, the improving conditions meant some nice reports all along the west coast and Hawaii for Laurence, KL7L / WE2XPQ.

In the Pacific, Merv, K9FD/KH6 / WH2XCR, QRTed shortly after local sunset due to changing weather conditions that led to antenna match stability problems.  Merv continued to make reports, including a spot of JA1PKG on the west and Rob, K3RWR / WH2XXC, on the east.

Other reports, statistics and anecdotes through the session:

Neil, W0YSE/7 / WG2XSV, operated his CW beacon through the early evening, being reported by John, VE7BDQ, and Steve, VE7SL.  Apparently the reports were significantly divergent, with Steve reporting single digit S/N values and John reporting mid to upper -20’s db S/N.  Its starting to seem like British Columbia is sitting on some type of RF vortex given the interesting data that has been coming out of there.

John, WA3ETD / WG2XKA, reported that my signal was being heard rather early again, at 0103z.  I suppose darkness is starting to favor the path between Texas and New England.  Its about time!

Doug, K4LY / WH2XZO, who has been working on an important research project took some time to elaborate on his recent receive antenna shoot out.  He indicates that for low angles, the 3 – element Hi-Z array is better than the loop with more decodes of WH2XXP, WH2XCR, and WH2XGP.  An apparent PC crash resulted in a loss of some  measurement capability but prior to this problem the loop outperformed the Hi-Z and inverted-L with all-time best S/N reports for XJM (+13), XXM (+10), XXC (+9),  XIQ (+7), and XXP (-9).  Thanks for the continued data, Doug!

Doug also reports that he has made arrangements with Carlos, PY2VM, for some listening time on 630-meter WSPR.  As Jim, W5EST, pointed out, its very noisy in Brazil at the moment, during their Spring in the southern hemisphere, so hopefully he will be able to hear some of us.  The key to success will be willingness of all stations to not give up.

During my morning CW session on 474.5 kHz, Steve, KK7UV / WH2XNV, reported my signal and even gave me a few calls.  The band was very quiet but propagation appeared to be one way as I was not hearing Steve at all, even after switching to receive antennas that favor the Northwest.  I suppose we are seeing latent effects of the recent CME-induced absorption.

Troy, N8WAC, of Walbridge, Ohio sent a nice note indicating that he was hearing my CQ this morning at an RST 519 at 1123z.  Troy was listening on a Kenwood TS-2000 and a 160-meter loop.  Its nice to see that the closed loop that is electrically small on 630-meters did not short all of the signal to ground, leaving enough to be detectable.

Ken, K5DNL / WG2XXM, indicated 48 unique stations reporting his signal.  Not surprising with band conditions so good!

We had a single new station that has been identified, N5DTX, who live across town from me.  I do not know him but hope to find out what his receiving set up is soon.
