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

Typical Operating Schedule

Usually QRV CW most evenings, tuning between 472.5 kHz and 475 kHz with CQ's on or near 474.5 kHz. Occasionally QRV JT9, 474.2 kHz dial + 1000 - 1350 Hz. QRV some mornings starting around 1100z on CW. Sked requests are welcome. All activity is noise and WX permitting

Very strong domestic and trans-Atlantic session while trans-Pacific openings remained North of the Equator including KL7L -> JA; Band improved as the evening progressed with many QSO’s and new grids reported in North America

North America was lightning free but there were periods in the late evening where lightning crashes were evident.    Southwestern Europe remains stormy  while many of the population centers in Australia are free of lightning although noise is most certainly elevated due to storms in the region.

Geomagnetic conditions are quiet.  The Bz is pointing to the North this morning and solar wind velocities are averaging near 300 km/s. DST values remain at positive levels.

 

 

 

Domestic propagation was fantastic for many stations in North America after the band had some time to calm down after dark.  Some QSB remained present, however.  Trans-Atlantic openings were strong but the path the Oceania from North America was poor while the path from Alaska to Japan was open.

For the low band digital mode operator, John, AE5X, reported on the 600-meter research group email reflector about a web tool called Hamspots that aggregates digital spots by mode and band but in a cleaner presentation, in my opinion, than what is reported by PSKReporter.  Registration (free) is required to use the system and it can be accessed here.

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 JT9 QSO’s with KR7O and KA7OEI.  Neil added that he “…heard the following JT9-ers but did not work them: NC0B, VE7SL, W7IUV, K1YQP (a new one in CA, -25), NO3M (-24), and KL7L (-23).”  Neil’s CW was heard at my stations here in North Texas during the late evening and was just below QSO levels.  He also offered the following statistics:

Al, K2BLA, reported a quiet night where he completed JT9 QSOs with VE3CIQ, N3FL and K8TV.  Al added that the last two stations were located in new grids for him.  Using WSPR overnight Al reported that he “heard 17 and heard by 56. No DX today.

Ed, W0SD, made an appearance on JT9, completing three QSO’s before reporting a PA problem.  He was operating at two-watt TPO.  Stations worked include NC8W, VE7SL and KB5NJD.  He will work to repair the PA in hopes of operating remotely from Arizona.

David, G0MRF, reported an FT8 QSO with EA4GHB.  David noted that Alberto’s best signal was -4 dB S/N at a distance of 1200 km.

John, WA3ETD, completed JT9 QSO’s with K9SLQ, KB5NJD, N3FL and K9KFR.

Fred, N3FL, completed JT9 QSO’s with K2BLA, WA3ETD and KB5NJD.

Bob, K9KFR, completed JT9 QSO’s with WA3ETD, WB4JWM and KB5NJD.

Tom, WB4JWM, completed JT9 QSO’s with KC3OL, K9KFR, KB5NJD and NC0B.

Larry, W7IUV, completed JT9 QSO’s with WB0DBQ and KB5NJD.

Ted, KC3OL, completed JT9 QSO’s with WB4JWM and NC0B.

Steve, VE7SL, completed JT9 QSO’s with W0SD and KR7O.

Robert, KR7O, reported that it was Quiet early on, but lightning crashes increased around 0600Z.  Signals seemed down, but still quite a bit of JT9 activity prior to 0600Z.  Worked KB5NJD, VE7SL and NC0B for the first time, also W7IUV and W0YSE worked again.  NC0B was 10dB or more down from his normally strong signal levels.  I missed the first CQs from K1YQP (CM98), but called him about 10 minutes later, with no reply.  Fred has been on WSPR with a reported +17 power and this is the first time I have seen him on JT9.  NO3M, K9KFR and W0SD were the other notable receptions.

Decoded 20 stations on WSPR, plus four different false decode callsigns, which is unusual for me.  Aside from K4SV, very little was copied beyond 2200km before 0700Z.  Copied K4SV (46/-17), WA9CGZ (-26), W4BCX (4/-27), W1IR (-28) and K2BLA (-19).

K9FD 3 spots, -19 (suspect Merv was not active)

KL7L 61 spots, -9.  Signals improved after 0945Z.  Also copied on JT9 from 0646Z, but weaker than usual.

VK4YB – nil

Keith, K0KE, reported that “It took the last two nights of transmitting WSPR on 630m at 1mw (0dBm) TPO to get a decode from VE6JY but it can be done,  -32 at 1694 km last night 0744z.

Roger, VK4YB, reported the presence of  “High absorbtion in VK. VK reports down by about 15dB on normal. I am unable to reach Hawaii on WSPR, nevermind North America. Not seen it this bad for ages, Space Weather shows no events.”  Roger also commented on recommendations from G0MRF regarding attempts to be reported in Europe, as posted on the RSGB-LF reflector:

My original hunch was based on the excellent openings we used to get on top band around Christmas time. It seemed to happen most years and reports of 59+ on SSB were achieved to and from EU on the best days. That did not happen this year and if top band is not humming then 630m is not likely to be possible. My detailed tests with VE6XH on 630m and 160m showed the similarities in propagation but there was only the odd occasion when 630m was open and 160m was not. There are also significant differences around sunrise. A sunrise enhancement is common on 160m and the band can still be open 15 or 20 minutes after official sunrise time. That doesn’t happen very often on 630m. Usually the band is dead or dying at sunrise and the peak may be 30 minutes or more before that. This was confirmed by analysis done by Jim, W5EST, in a recent post on the KB5NJD 630m daily report. My early morning reports into Japan closely follow that analysis. Sunlight comes over the top of the Txing station causing D layer absorption to the West of the station before sunlight reaches the station at ground level. At the time of the peak signal in Japan, only Scandinavia is in full darkness. There are receiving stations there but I reckon my signals have been 20dB or more below threshold level owing to the general poor propagation. These trials are not for the faint hearted and will continue, but probably not every day as I am back to work on Monday.

Ken, K5DNL, indicated that he operated WSPR overnight, reporting 26 stations and he received reports from 92 unique stations including EA8BFK, K9FD (/KH6), YV7MAE, ZF1EJ and eight Canadian stations.

This session was a nice rebound from the previous at KB5NJD.  The band was slow to develop in the early evening but I really think it was much too early to have the expectations that many of us were having (an hour earlier than the previous session at the start!).  JT9 QSO’s were completed with WB4JWM, WA3ETD, K1UTI, W0SD, NC0B, NO3M, NC8W, KR7O, VE3CIQ, N3FL, K9KFR, KA7OEI, W7IUV and WA9CGZ.  I made a few calls on CW but nothing new was reported.  I received a few reverse beacon reports  during the evening and heard W0YSE before bedtime.  Its been enjoyable to work so many stations and I hope to see similar improvements in activity on CW on a regular basis.  There have been a number of active stations including K4EJQ and K8RYU.  Storms are possible tonight into tomorrow here in North Texas so its possible that I will be QRT at some point for bad weather.  At least its not ice.
