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

Current Operating Frequency and Mode

OFF AIR but returning after dark on Saturday night

More western trans-Atlantic reports: WH2XXP -> TF3HZ and WG2XXM -> LA2XPA; Was WD2XSH/17 possibly observed in VK4YB’s waterfall without decode?; Band activity continues as seasonal high levels

– Posted in: 630 Meter Daily Reports, 630 Meters

It was another very good night for propagation and generally low noise levels although select areas reported more precipitation QRN while others had full blown storm QRN.  Lightning crashes from gulf coast and southeastern coastal storms were heard here in Texas but seemed very distant and near the noise floor.


12-hour North American lightning summary


Geomagnetic conditions have ramped back down as quickly as they escalated  in the previous session.  Unsettled to G1 storm levels are forecast for coming sessions but so far unsettled conditions have not yet been observed.  The Bz has been variable, ranging from slightly Northerly to slightly Southerly and is currently pointing to the South very slightly.  Solar wind velocity is up a bit but still in the low category and very calm, averaging 360 km/s.  DST values have generally followed closely to unity although the negative side has dominated through this session.







Trans-Atlantic reports continue to be very strong for the Northeast Atlantic coast in addition to reports for Oklahoma and Arizona.  WG2XXM was reported by Rolf, LA2XPA.  WH2XXP was reported by Halldor, TF3HZ.  WD2XSH/17 continues to have strong nights from coastal Massachusetts, with reports from F1AFJ, F1AFJ/1, G0LUJ-1, G3XKR, and TF3HZ.  Report details for these stations can be viewed here.

Doug, K4LY / WH2XZO, was located near the southeastern QRN source but even so he indicates a few high S/N reports, decoding fourteen WSPR stations.  Doug adds, “Excellent activity again, and 51 unique spots received ties record of two nights ago.”

Rick, W7RNB / WI2XJQ, reports that he decoded twelve WSPR stations (plus one phantom) and was decoded by 35 unique stations.  Rick’s unique report detail can be viewed here.

Neil, W0YSE/7 / WG2XSV, reports:



Ken, SWL-EN61, located in Indiana, reports “another night of good activity… 18 unique stations heard.”

I’ve recently been conversing with Al, KB6KAX, who had a successful first night of WSPR reports on 630-meters.  He provided these report details:

“I wanted to share the WSPR I received last night about 9 PM PT , on 474.2.  I’m new to playing with WSPR so I just copied the list that I heard … here it is:

WH2XGP in Quincy,WA … WG2XXM in Shawnee,OK … WG2XSV in Vancouver,WA … WG2XIQ in Duncanville,TX

0450  -10  -0.2    0.475607    0   WH2XGP        DN07     37  12824

0452  -17  -0.1    0.475631    0   WG2XXM        EM15     37  11858

0452  -24   0.5    0.475679    0   WG2XSV        CN85     30  12571

0456   -5  -0.2    0.475607    0   WH2XGP        DN07     37  12824

0456  -17  -0.1    0.475632    0   WG2XXM        EM15     37   1787

0456  -21  -0.2    0.475712    0   WG2XIQ        EM12     37  12509

a number of signals also IDed in CW sometimes …I was amazed some I could hear well but most of the time it was like 90% noise yet WSPR decoded it …”

Al added that he is using a TS-430S for a receiver and the antenna is a simple 100 foot long wire pointed Northeast, about 30 feet off the ground.

Trans-Pacific report details for this session (excluding KL7 and KH6) are aggregated here.

Roger, VK4YB, submitted this interesting analysis for the session.  The 0904z time slot is very interesting:

“I had very low noise here this evening which coincided with the usual sunset enhancement. For the first time in a long time, I was able to see several weak signals in the waterfall along with the expected signal from WH2XXP. WG2XXM was the first to decode and I wondered if the band was “long”. I started to note down the frequencies and time slots of the traces. I was hoping some of the  stronger East coast stations might be identified. I studied the frequency lists and transmit times of various stations to identify possible sources. Here are the results:

Time                       Frequency                  Source
08:54                            740                           ?
08:54                            750                likely WH2XCR, not WH2XZO
08:58                            612                possibly WI2XJQ
08:58                            693                likely WH2XGP
09:00                            672                possibly WE2XPQ
09:02                            670                ?  not WE2XPQ
09:04                            745                possibly WD2XSH/17, not VE3CIQ
09:20                            695                likely WH2XGP
09:20                            710                likely WG2XXM
09:20                            737                likely VE7BDQ
09:26                            786                ?  not WG2XIQ
09:36                            608                ?  not WI2XJQ
Where I have said “not” a particular station is because, although using that frequency, they were not transmitting in that time slot. All the “possibles” were transmitting at the time of observation.
Quite a few of those were very faint, but one that was fairly distinct was the one at 09:04, which is the most interesting of all. If my surmise is correct, a few more dB would have produced an extremely long haul DX spot for WD2XSH/17 over a path which I think is achievable.
73 Roger, VK4YB”
Roger provided reports for WG2XXM, WH2XGP, WH2XXP, and WI2XBQ and received reports from JA1NQI-3, JA1PKG, JA3TVF, JE1JDL, N6RY, W1CK, and W7IUV.

Ken, K5DNL / WG2XXM, reports that he was decoded by 64 unique stations including VK4YB and LA2XPA.  Ken received 88 WSPR decodes from WH2XCR, best at 0 dB S/N.

Joe, NU6O / WI2XBQ, reported, “A very good night. Heard by 35 including vk4yb and zf1ej, I had 4 spots of vk4yb…”

Ward, K7PO / WH2XXP, received reports from 64 unique stations, including VK4YB, VK2XGJ, and the previously reported TF3HZ.

Larry, W7IUV / WH2XGP, reports that as W7IUV and listening on the western receive antenna he decoded thirteen WSPR stations, including VK4YB as well as a few eastern stations.  As WH2XGP and using the eastern BOG, Larry decoded seventeen WSPR stations including a significant number of eastern stations.  He was decoded by 54 unique stations, including VK4YB, ZF1RC, ZF1EJ, and ZL2BCG, as well as a number of eastern stations.  He adds that the East / West paths were much stronger than the North / South paths.

This was a very good night for receiving and transmitting although I was limited to WSPR as the variometer drive motor is currently frozen due to Winter weather.  Overnight receptions, like transmissions, were plentiful, in fact for the first time in recent memory over 1000 receive reports were generated by my station, almost double the previous peak this season.  It was nice to share two-way reception reports with WE2XPQ.  Transmission reports resulted in numerous periods of strong, easy CW-level reports.  The band sounded fine.  I hope to return to CW in the morning as we will warm up today.  My WSPR transmission report details can be viewed here and my WSPR reception report details can be viewed here.


WG2XIQ 24-hour WSPR activity


Activity was extremely high during the evening but I did not take a formal census and did not see any other reports, other than that activity was very high.

ZF1RC 24-hour WSPR activity


Laurence, KL7L / WE2XPQ, reports that the band was “OK” but there were no JA reports so far.  He provided reports to VK4YB and was heard by WB0VAJ and shared two-way reports with me, which I am very happy about.   Laurence’s report details for this session can be viewed here.


WE2XPQ 24-hour WSPR activity


Merv, K9FD/KH6 / WH2XCR, shared two-way reports with VK4YB and WE2XPQ and provided reports to ZL2BCG, WG2XKA, and WH2XZO.  VK2XGJ, JA1NQI-2, JA3TVF, and JH3XCU provided reports for Merv.  Merv’s DX report details can be viewed here.
