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

Current Operating Frequency and Mode

CQ 474.5 kHz CW and alternately tuning 472 kHz - 475 kHz for signals.

The band redeems itself with strong propagation through the session on the doorstep of another forecast geomagnetic storm, Strong participation, FR5ZX returns!

– Posted in: 630 Meter Daily Reports, 630 Meters

Last night yielded some of the strongest propagation we have seen in quite some time here in the lower-48.  Numerous signals across the band were at positive S/N levels for extended periods and as Ken, SWL/EN61, said in the ON4KST chat/logger, “You know the band is good when calls like WH2WYW are getting logged. Audio overloading of pc soundcards.”  Larry, W7IUV / WH2XGP, indicates that last night was the best night in several weeks at his location in Washington state.  Larry has been fighting ice on his antenna so it helps to be able to transmit!  Doug, K4LY / WH2XZO, reported a very strong night  in spite of storms in his region.  Doug, like many others, were at easy, arm-chair CW levels through much of the evening.  I made some impromptu calls on CW from 0230z – 0300z but did not receive any answers.  Ken, SWL/EN61, heard me and sent this recording of two back-to-back CQ’s fired off from my station during that time frame:


Geomagnetic conditions were very quiet and stable through the session but perhaps this is the calm before the storm.  The Space Weather Prediction Center has issued a warning for G3 storm levels today into the next session.  As I write this report, the Bz component is stable at 0 nT and the solar wind is low, near 350 km/s.  The K index remains quiet and stable.

WSPR activity was very high through the session, with 87 MF WSPR stations reported on the WSPRnet activity page at 0330z.  There were several new stations identified through the session in spite of a station in the Northwest that is having problems making clean band changes and subsequently polluting the MF band map.  Accidents happen but when it happens again and again and again, procedures need to change to prevent the problem from continuing to occur.  If you don’t know what this means or don’t know how to prevent the problem, send me a message on the Contact page and I will help you.  New or newer stations include VE5SR and AC2PJ.  Welcome aboard.

Daytime WSPR activity from here at WG2XIQ was the best I’ve seen in a few weeks, with reports from numerous stations in the Midwest and east at or near JT9 QSO levels.

In the Pacific, Merv, K9FD/KH6 / WH2XCR, was able to make a few reports through this session before the sound device failed again.  He continues to troubleshoot the problem.  Thanks for all the effort, Merv!

Other anecdotes, comments, and statistics from the session:

Ron, NI7J / WH2XND, reports that Ward, K7PO / WH2XXP, was spotted by 42 unique stations through the session while running 40-watts TPO.

Neil, W0YSE / WG2XSV, reports that his 1-watts ERP was reported by 17 unique stations.

Doug, K4LY / WH2XZO, indicates that Steve, VE7SL, reported his station 31 times through the session with 11 total unique stations heard.  Steve was testing WSJTx through this session.  Doug also reported that WG2XXM and WG2XIQ each  had 44 unique stations reporting them through the session.

Ken, SWL/EN61, in Indiana reports that Doug, K4LY / WH2XZO, was received at his station at +10 db S/N, which was the record high received signal for Ken’s station.

There has been some discussion about a February special event.  If you are interested in transmitting, receiving, or both, be sure to send Fritz Raab a note supporting this event so planning can get under way.

Its good to see activity beginning to re-emerge.  I suppose this means that the holiday hangover is wearing off.
