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

Current Operating Frequency and Mode

OFF AIR for storms, probably for much of the week if the forecast holds

Trans-Atlantic openings in the East are plentiful for another night; Trans-Pacific openings are depressed once again; Domestic openings continue to be very strong around North America; Tonight is the 2nd Annual Midwinter 630-meter Activity Night!

– Posted in: 630 Meter Daily Reports, 630 Meters

The summary from February 4, 2016 can be viewed here.

Propagation was great around North America with big signals from both coasts and all points in between.  Noise levels were very low here in Texas once again and I have not seen any reports of high QRN anywhere in North America.  There were reports of elevated noise levels in Oceania, however, and trans-Atlantic reports were numerous for eastern stations, suggesting quiet conditions (quiet enough!) in Europe.  Activity was also very high ahead of tonight’s 2nd Annual Midwinter 630-meter Activity Night.  At the moment it seems like it should be a good night for QSO’s and stations providing reports.

12-hour North American lightning summary


Geomagnetic conditions have returned to elevated-quiet levels throughout this session.  The Bz has been stable, remaining near unity for much of the session with a few periods of slight variability.  Solar wind velocities have decreased to moderately high levels, averaging 525 km/s.  DST values experienced periods of decrease through the session as has been the case thought this most recent geomagnetic event but the values are currently approaching the center line again.  Is recovery about to return?  We seemed to do pretty well this time under disturbed conditions!




Trans-Atlantic openings continue to dominate the session.  There were no real surprises as seen during the peak of the most recent geomagnetic event – only point A to point B on open, quiet paths.




WG2XPJ –> F1AFJ, F59706, G8HUH, PA0A, PA0RDT


Report details for these stations can be viewed here.

Paul, N1BUG, reported no transcontinental openings during this session from Maine but he did receive G8HUH on the trans-Atlantic path.

Al, K2BLA / WI2XBV, reported that he decoded fourteen WSPR stations and was decoded by 38 unique stations.  He indicates that he thinks, “…that beats my last hrd by record by one.”  Al reported WH2XCR at -22 dB S/N which may have been his best ever for Merv but notes that he was not reported in KH6 during this session.

Rick, W7RNB / WI2XJQ, reported that he provided reports for eight WSPR stations and was reported by forty unique stations.  Rick’s unique report details can be viewed here.

Larry, W0OGH, in Arizona, submitted these comments about his session success on the 600-meter research group email reflector:

“I don’t know if it’s outstanding conditions or beginners luck.  I finally figured out how to get the MF signals through the K3 and have enjoyed the 472 kc band ever since.

I lost a couple of hours of data, unbeknownst to me my WSPR program had dumped after a couple of hours of being in use, that’s a new one for me.

I still copied 16 stations among which were WH2XCR in Hawaii, VE3CIQ in FN15, VE7CNF in CN89WI2XBV in EL99, WI2XRM in EL98, WG2XKA in FN33, WD2XSH/17 in FN42, CF7MM in CN89 and ZF1EJ in EK99 as best long haul stuff.  ZF1EJ was in here from 0356 till 0912Z and WH2XCR in BL11 was copy-able from 0556 till 1238Z.

XXM and XIQ are almost like regulars with XXM peaking at +9 one time and XIQ hitting the -10 level on the WSPR scale.

Looking forward to tonight with maybe some JT-9 stuff to see how well i can copy that…”

Trans-Pacific report details, excluding KL7 and KH6, can be viewed here.

Roger, VK4YB, reported that band conditions were similar to the previous session.  He added that “heavy static from active storms in NSW is easing slightly which may allow some late rx spots.” Roger received reports from JA1NQI, JE2JDL, JH1INM, TNUKJPM, and VE6XH.  He provided reports for WH2XXP and WG2XXM.

Phil, VK3ELV, received reports from JH1INM, JA3TVF, and TNUKJPM.

Ken, K5DNL / WG2XXM, reported that he decoded eighteen WSPR stations and was decoded by 72 unique stations including VK4YB.

Ward, K7PO / WH2XXP, received reports from 76 unique stations including VK4YB.

Neil, W0YSE/7 / WG2XSV, operated a JT9 beacon overnight and received reports from Mark, KU7Z:

Neil added that  he was surprised by the -28 dB S/N report because he “…thought JT9 was only good to about -25.”  My experience has been that it depends on a number of factors including fades within the transmission that might not completely impede decoding and while I would never feel confident about embarking on a QSO at -28 dB S/N, I’ve completed JT9 QSO’s just that weak before… that’s pretty good to approach the WSPR detection limit with JT9.

Neil also reported that a few WSPR stations were decoded between his 1-minute JT9 transmissions:

Neil will be on the air again tonight during the special event with a JT9 beacon including his CW ID.

Mike, WA3TTS,  reports, “Trans-Pacific path still open, but at only about half the decode rate of the prior evening.I thought about going to single band 630m only reception, but I wanted a comparison with last evenings reception with the same dual band 630m/2200m receiving arrangement.”

“Also heard WG2XSB on 471.0 kHz CW all night beaconing from FN42. I looked for VO1NA on 477.7 but no joy. 73 Mike wa3tts”

Band conditions continue to be very good here at my station.  Like the previous session, both transmission and receive reports were plentiful and very good for domestic paths.  My WSPR transmission report details can be viewed here and my WSPR reception report details can be viewed here.  I operated a bit of unannounced JT9 in the early evening to help one station that was trying to evaluate his JT9 settings.  There was a bit of confusion with the timing of the transmissions but because he had left his decoder running he had decodes of my signal when he checked later.  I will be operating CW and JT9 tonight in the special event.

WG2XIQ 24-hour WSPR activity


Activity was extremely high from before local sunset here in Texas, with nearly 120 MF WSPR stations reported on the WSPRnet activity page.  At various times through the evening I checked the activity page and found that activity ranged from 132 stations on the low end to 146 at the high end.  There were also many new stations participating.  I’m not sure if they thought the special event was during this session or not.  Perhaps it was a warm up to evaluate their systems, for which WSPR is really good.

Eden, ZF1EJ, had a great session with a return of trans-Atlantic reports from G8HUH and PA0O.  Coverage in North America was consistent and Eden shared two-way reports with WH2XCR.  He received reports from 42 unique stations and provided reports for fifteen  WSPR stations.

ZF1EJ 24-hour WSPR activity


Laurence, KL7L / WE2XPQ, experienced a strong session, with reports from  7L1RLL4, JA3TVF, JE1JDL, JH1INM, JH3XCU, TNUKJPM and he shared two-way reports with VK4YB and WH2XCR.  Laurence is also listening remotely while on an excursion in KH6.  While the location is geographically better than in past trips, with a relatively clear path to the East, high noise levels impeded his reporting overnight and his only reports were for WH2XCR.  Laurence’s DX report details for WE2XPQ can be viewed here.

WE2XPQ 24-hour WSPR activity


Merv, K9FD/KH6 / WH2XCR, continues to receive reports this morning from VK4YB and VK2XGJ at sunrise and even later.  Other paths from KH6 were typical, with reports from JA3TVF, JE1JDL, JH1INM, JH3XCU and TNUKJPM.  Merv shared two-way reports with ZF1EJ, WE2XPQ, and VK4YB.  In the eastern US, Merv shared two-way reports with WH2XZO and WG2XKA.  DX report details can be viewed here.

WH2XCR 24-hour WSPR activity
