13560 kHz Time Signal ? 0100 UTC 15 Jan 2018

Token: I just took a listen to your web SDR. What I hear right at the moment on 13.560 USB sounds closest to what was coming from the gas pumps at the convenience store. (Very fast pulses).

Indeed, a mobile SDR expedition with the ability to see signals as well as hear them could prove interesting.

I was hoping this forum would relate to actual Beacons with IDs  ...
Maybe this thread would best be put in the mystery signal area.

Also, if a person is going to put the effort into putting a beacon on the air it's general
location would be important for listeners so they could determine propagation paths...

Maybe I'm alone in my thinking. That won't be the first time. LOL

0621 UTC 12/25/24 Picking up lots of beeps. The strongest one beeps 4 quick bursts. They all seem random and are different tones. No idea what it is.

Hearing similar beeps and tones at 0654z on 13.559 MHz on my HF log periodic pointed WSW in Middle Tennessee. Sounds local, as there's no QSB. There's a small gas station/market about a mile in that direction. Otherwise, I'm in rural/suburban area.
