KMUD 6935 AM 0255 UTC 17 April 2022
« on: April 17, 2022, 0305 UTC »
KMUD on 6935 AM, with CW and voice ID, starting at about 0255 UTC, 17 April, 2022.

S8 here (edit, 10 over S9 on the right antenna).

T!

(edit) at about 0346 UTC KMUD took a big dive, from  10+ over S9 to S4 or less in about 60 seconds.  At the same time 6930 USB came up in signal.  Looks like a major band condition change at that time.

Songs are identified with Shazam if needed. I usually use KiwiSDR receivers. Reception from my QTH is using an SDRPlay RSP1A for SWL with a 40 meter band Inverted V at 40 feet. Kenwood TS-570D for ham use.

Token,

Your remarkable report and the near-abrupt shift from short skip to long skip on 6.9 MHz band / 43m was likely the X1 flare that began a radio blackout over s.e. Asia at 03:34 UT! A proton stream struck at the time of the UV and X-rays, so it immedisately affected the night and terminator ionosphere, also... 73MB

Yeah, I saw that flare and assumed that was the cause.  I was a little surprised that 6930 USB came up as a result of the flare, but that was a short term impact, that signal also tanked a few minutes after my post.  Also, since this was well after sundown I was impressed by how much, and how quickly, the propagation was impacted by the flare.

Looking at my wideband waterfall the change in propagation, across the spectrum, was very clear, but the bands appear to have recovered by shortly after 0400z
