Title: 7182-7196 kHz -- digital or radar?
Post by: Dr. Amp on February 25, 2024, 0017 UTC

Not sure what this is -- it sounds different, and looks more fine-grained, than radars I've heard before, but I'm no expert.

Also, on 7200 LSB, there's a continuous beep-beep in the background.  I know this frequency is heavily QRMed, but this sounds very similar to ALE to me.

And now it's gone... it was there for quite a while before I posted.  (The beeps on 7200L are still there.)

Without recordings, date and time in UTC, or a bit more description, there is no way to know what you are describing.

As for the radar, a bit before you posted this the Russian 29B6 radar was on that frequency.  However I don't know how long before you posted this you heard what you heard and it was not on that freq at the time this was posted.

T!
