Title: 13242 kHz AM UNID 1923 UTC 11-DEC-2024
Post by: Gr0undPlan3 on December 11, 2024, 1931 UTC

Does not sound like CW but looks like CW on the waterfall. 41 to 59.

Can also be heard on the HFU SDR, so not local to EN80.

USB/LSB just looks like a digital hash. Any ideas?

Signal gets very strong during the last half of the USB recording, might want to skip ahead.

Hi.

Please use SSB for reception, AM makes no sense if you want us to help identify the signal.

Regards.

I'll try to capture it again in USB, at the time there was nothing there when I switched to USB or LSB. AM was the only mode where there was a signal present. Thanks.
