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

Current Operating Frequency and Mode

OFF AIR but will be QRV on CW somewhere between 472.5 kHz and 475 kHz after dark

SCHEDULED ACTIVITY: CQ 474.5 kHz CW by 1030z through sunrise most days, WX permitting

Another low-key night as weather continues to impact activity and operating, Propagation good enough to yield more reports for WE2XPQ at JA1NQI

Its difficult to make an accurate determination of band conditions last night with so many stations effected, both transmit and receive, but the geomagnetic field was quiet and generally very stable compared to previous sessions that saw spikes.  Elevated solar wind dominated the early portion of the session, however, exceeding 500 km/s.  As I write this report, levels have calmed to below 400 km/s.  The Bz component, as reported by the Space Weather Prediction Center, was remarkably stable, remaining at or near 0 nT throughout the session.

The Kyoto DST was generally stable and remained just below 0 nT.

The Australian DST indicates a significant positive shift compared to previous sessions.

I briefly checked the WSPRnet activity page during the evening and 66 stations were reported on MF at the time.  Two new (newer) stations were reported through the session: W4APO and AD7XG.  Gary, AD7XG, provided an email report to the 600-meter research group email list, reporting WSPR from Larry, W7IUV / WH2XGP, at S9 off frequency in Davenport, Washington using an Icom 756 Pro III and beverage.

In the Caribbean, Eden, ZF1EJ, was present, reporting as far as the Pacific Northwest and WH2XGP.  Roger, ZF1RC, was listed on the WSPR map but had no reports in the database.

In Alaska, Laurence, KL7L / WE2XPQ, appears to have been the focal point of propagation, with three reports from JA1NQI in addition to stations along with west coast of North America.

In the Pacific, Merv, K9FD/KH6 / WH2XCR, continues to be plagued with sound card problems.  We are working through some troubleshooting options as we seek a loaner / donated out-board sound device to try to get him back on the air.
