Contineous signal at 148.5MHz - Identification help

Post by snabil » Sat Jul 11, 2020 7:47 am

Hello,

I recently came across a continueous signal at 148.5MHz. Ths signal is strong and does not shift or drift in frequency. I can see it transmitted 24/7 without interruption.

I recorded it with SDR# (Baseband and Audio), and tried to decode it with the tools I know of (wxtoimg, and DSD+), but could not get any valid data.

I would appreciate your help in decoding the signal.

The download link:

Thanks,

Well, 148.5MHz is the pixel clock frequency for FullHD...

He means that the signal is probably coming from your PC monitor as unintentionally emitted radiation.
