Title: 9977 kHz at ~6kHz wide Data?
Post by: CaptnKliegle on June 19, 2020, 1053 UTC
Checked with Wiki ID, didn't see anything looking like it (or sound like it).
I made a recording via SDRC:

Honestly, to me that does not look like data to me, it looks like a carrier modulated with a 325 Hz tone.  Alternately, it could be FMCW of some kind, sinusoidal, sawtooth, etc, with a 325 Hz modulation rep rate.

T!

To me looks like psk modulated carriers, if the entire sig was captured could take a closer look at it.
