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

Current Operating Frequency and Mode

OFF AIR; QRT Thursday night but back Friday morning by 1100z

Profoundly disturbed geomagnetic conditions don’t disrupt all trans-Atlantic activity; QRN in the East decreases as storm system moves out to sea; Trans-Pacific openings favor path to JA as high QRN impacts openings to Oceania; Big aurora in Alaska

Noise was improved here in Texas overnight but stations further East report that their noise levels remained at high levels with heavy rain and high winds further complicated their activities.  At least the lightning was less prolific than the previous session  based on lightning statistics.

But noise was probably the least of a radio operator’s worries during this session as geomagnetic conditions reached G2 storm levels due to a geoeffective coronal hole.  While the Bz is currently pointing to the North, solar wind velocities currently exceed 700 km/s and DST values approached -60 index units during the overnight period.  The good news is that the most recent reports have moderated to unsettled levels and DST values have moderated by about half from the lows.  This event may have repercussions for a while.




Trans-Atlantic openings  were different during this session, generally favoring a more East to West paths overnight during the peak of disturbed geomagnetic conditions.  There were a number of early reports to and from Europe even some in full daylight in New England.  Report details can be viewed here.






Paul, N1BUG, reported that QRN complicated his ability to assess propagation but he managed reports for eleven WSPR stations including EA5DOM.

Phil, VE3CIQ, reported that Winter returned to Ontario as his antenna match wandered 4 kHz away from where it had been centered.  Phil provided reports for seven WSPR stations and was reported by 21 unique stations.

Al, K2BLA / WI2XBV, reported high noise during the evening that was subsiding this morning with the passage of the frontal system.  He provided reports for eleven WSPR stations and was reported by 29 unique stations including two-way reports with WH2XCR in Hawaii.

Doug, K4LY / WH2XZO, started the evening with high winds, heavy rain and lightning but after a late start he managed to provide reports for thirteen WSPR stations  and he was decoded by 32 unique stations through “summer-like QRN.”

Ken, K5DNL / WG2XXM, reported that he decoded twelve WSPR stations and was decoded by 57 unique stations including EA8/LA3JJ and two-way reports with WG2XCR and ZF2EJ.

Rick, W7RNB / WI2XJQ, reported a bit of a rebound for the session but high QRN and geomagnetic conditions continue to have an impact.  He provided reports for six WSPR stations and was reported by 24 unique stations including ZF1EJ.  Rick’s unique report details can be viewed here.

Neil, W0YSE/7 / WG2XSV, reported good transcontinental conditions overnight.  He provided the following comments and statistics:

Mike, WA3TTS, reported:

“Looks like the geomag disturbance and the wx QRN kept the door closed to the PNW for the most part. XGP did manage to make the path several times….”

Hideo, JH3XCU, posted two links in the ON4KST chat to tables illustrating DX -> JA report totals and peak S/N for each station.

Roger, VK4YB, reported, “Lightning visible most of the evening. Surprised I decoded anyone. I am expecting a lift in conditions in March, but no sign of that yet. JA path is in the doldrums.  630m/160m tests with VE6XH continue. 160m 7 spots, best -23, 630m 1 spot at -27.”  Roger received reports from CF7MM, VE6XH, and W7IUV.  He provided reports for WH2XXP and WH2XGP.

Larry, W7IUV / WH2XGP, provided reports for eleven WSPR stations and was reported by forty unique stations including VK4YB and JH1INM.  As W7IUV, Larry provided reports for seven WSPR stations including VK4YB.

Ward, K7PO / WH2XXP, received reports from 58 WSPR stations includingVK4YB, JA1NQI, JA3TVF, JA8SCD5, JH1INM, and JR1IZM.

In response to comments posted by Max, IK0VVE, on the RSGB-LF reflectors about his success running just 200 mW TPO, Roger, G3XBM, offered the following response and encouragement:

“Even with my earth-electrode “antenna” in the ground Italy, Spain, Norway and many other countries were spotted last night on my “deaf” FT817 on 472kHz WSPR.

My message is always experiment and be surprised. Even with 200mW from the amp, it would not surprise me if you are widely spotted.”

This was a moderately better session for noise but I admit that I was so starved for some actual operating that I forgot about the poor geomagnetic conditions and pushed ahead with a little evening JT9 and CW.  No additional QSO’s were registered but it was nice to do something more than WSPR.  Reception reports were down from the previous session which is bizarre as it was noisier in the previous session.  Even so, receiving was still good and those details can be viewed here.  Transmission reports were also normal and very good.  Domestic conditions and two-way DX activity with WH2XCR and ZF1EJ was easy.  Transmission report details can be viewed here.

WG2XIQ 24-hour WSPR activity


There was quite a bit of activity during the evening, with 132 MF WSPR stations observed on the WSPRnet activity page at 0200z.  After a number of weeks where receiving stations made band changes relatively carefully, a couple of stations really polluted the WSPR map with bad data due to poorly executed band changes.  Please use good judgment when changing bands.  That said, the North American map for this session is severely compromised.

Regional and continental WSPR breakdowns follow:

North American 24-hour WSPR activity


European 24-hour WSPR activity


Asiatic Russian 24-hour WSPR activity


Japanese 24-hour WSPR activity


Australian and New Zealander 24-hour WSPR activity


Eden, ZF1EJ, provided reports for ten WSPR stations and received reports from 22 unique stations including two-way reports with WH2XCR.

ZF1EJ 24-hour WSPR activity


Laurence, KL7L / WE2XPQ, continues to be QRT but submitted the following images of aurora from his QTH:


Merv, K9FD/KH6 / WH2XCR,  reported heavy storms in the previous session but it was his feeling that the bulk of the system had passed by evening as temperatures plummeted from recent highs.  Merv’s session was strong, sharing two-way reports with ZF1EJ and VK4YB and providing reports for VK3HP.  Merv received reports from VK2XGJ and ZL2AFP with continued very strong coverage in Japan with reports from 7L1RLL4, JA1NQI, JH3XCU, and JR1IZM.  The East to West paths were particularly strong and coverage of North America was very good with two-way reports for eastern stations including WI2XBV and WH2XZO.  The band was very much open.  DX report details for the session can be viewed here.
