It could have been a close-by radio transmitter which saturated and desensed the receiver. Dave - W?LEV

Thanks Sabine but highly unlikely it is a bad coax connection...it lasted only 20 seconds and spectrogram returned to normal and whatever it was never occurred again. Thanks for looking John..the

Hmmmm. I wonder if my spectrograms show the total lunar eclipse on March 14, 2025? It had its penumbral phase starting at 03:57 UTC and partial phase starting at 05:09 UTC , and totality starting at

Thanks Tom. Yours looks pretty devoid of background band noise in the post-dawn hours as well. -- Dave

Hi Dave, Here is my March 22 2025 spectrogram. Hope it helps you. - Tom

Hi Bill, it looks more like a bad connection at the antenna feed point or at a connector. Anything with hard edges in the spectrogram is suspicious. Sabine -- Germany Standard time: UTC +1 hour

Dave already pointed this out: Something was strange within the ionosphere during the day. The band noise was low and the teepees were already there before sunset. Sabine -- Germany Standard time: UTC

Today there was very little band noise in the morning (1200-1700 UTC ). SWPC did not report any X-ray flares. Also, the preceding day's band noise took longer than usual to decay. Was there a CME

Hi John, Excelllent Work?? Salvador

Bill:? ? ?Here is my two cents. I looked at SkyPipe 20.1 MHz and did not see a signal dropout. With that said, your data seems to show some dropout ?from 16:19:40 to 16:20:20. With my knowledge I
