On April 13th 2025, I managed to receive some odd signals on 14.090.00 which sounded just like packets of information being sent.
What’s weird is that I only heard this one this particular frequency twice, on the 13th and a day prior.
Here is a recording of those:
Currently, I’m using a Kenwood TS-430S with a homemade wire listening antenna.
I should receive a better antenna very soon, so maybe this frequency is allocated for something I am not aware of yet.
