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

Unsettled conditions continue but propagation looks pretty good; WSPR maintenance overnight contributed to lost reports

– Posted in: 630 Meter Daily Reports, 630 Meters

Propagation was pretty good after a slower start than observed in the previous three sessions.  There were no early reports for WD2XSH/15 at my station as had been recorded previously but initial reports were received from W5EST just miles away from XSH/15 near Little Rock, Arkansas.  There were mentions of regional high noise levels early in the evening and this was the result of more active storm systems across the South and East.  Further North, auroral activity hampered early propagation, likely due to increased absorption.  The band stabilized a bit after dark but the noise level increase was significantly more obvious than earlier.  This morning I was unable to null storm noise for my morning CW sked in spite of the primary loop being located broadside to the storms in Oklahoma.  WSPRnet maintenance resulted in some system downtime overnight and may have contributed to some of the depressed numbers compared to previous sessions.  Hopefully all of that will be completed now and the upcoming season will be problem free.

Geomagnetic activity has been variable, ranging from quiet to unsettled.  The Bz has been solidly pointing to the South and solar wind velocities are in excess of 600 km/s, in the very high category.  DST remains in the “trashed” category:

Phil, VE3CIQ, reports that he was decoded about 86 times overnight with a similar number of signals decoded.  He indicates that he was operating at a 20% transmit level rather than his normal 25%.  He decoded WSPR from WG2XKA and WG2XXM and was decoded by KB3X, VE2PEP, WA3TTS, WG2XKA, and WI2XFI.

John, WA3ETD / WG2XKA, submitted the following comments:

“Conditions seem to be slightly improving, although noise levels remain very high.  XKA was heard by five, and spotted three with the best DX being WG2XIQ.  Extremely heavy foliage near both antennas is definitely affecting my operations at the present.”

Ken, K5DNL / WG2XXM, reports that he decoded two WSPR stations and was decoded by 22 unique stations.

Roger, VK4YB, reports “Noise floor -75dBm, Waterfall is a featureless carpet, only a few locals can penetrate. Depressing sight.”

Steve, VE7SL, reports that he decoded five WSPR stations and was decided by fourteen unique stations.  He decoded WH2XCR 38 times and notes that “…things improving. I think that geomag hit was worse than expected.”

Rick, W7RNB / WI2XJQ, reports that “WSPRnet was down for some time, not sure how long but it was still down at 3AM local time but was back this AM. So, I’m not sure of my report being complete.  But here is what I have — Heard 4, heard by 9.”  Rick also noted that he had twelve decodes of WH2XCR and ten for WG2XXM:

There were no reports from the trans-Atlantic, trans-African, or trans-Equatorial paths.  UA0SNV was present but no reports have been filed at this time.

In the Caribbean, Eden, ZF1EJ, reported WG2XXM and WG2XIQ:

Laurence, KL7L / WE2XPQ, reports fair but improving conditions as the geomagnetic field remains very active in Alaska.  Laurence performed a “shoot out” between two probe, on of which was higher and further away, typically yielding 1 dB or better improvements.  KL7L was designated as the W1VD “AMRAD clone” at 20-foot and nested in trees while WE2XPQ was the L400B at 35-foot and comparatively “in the clear” with respect to trees:

Merv, K9FD/KH6 / WH2XCR,  may have been a victim of persistent geomagnetic activity as Roger, VK4YB, noted  an empty waterfall on his console.  Even so, the usual reporting stations and stations being reported were present.  Merv has established that these paths generally persist throughout the Summer in the northern hemisphere, something that has never been so completely observed at 472 kHz as we have seen this year:
