Digital Signals around CB channels 24 & 25 LSB - 27235Mhz and 27245Mhz
(1/1)
5150:
Anybody know what these digital signals are around 27233.50 Mhz and 27236.50 Mhz LSB? There are a lot of them.
Then there are a ton of signals around 27243.50 Mhz and 27246.50 Mhz LSB as well with a lot of traffic.
I tried WSJTX, FLDIGI, JS8CALL, ROS, and MULTISPK but couldn't decode these, but maybe I wasn't patient enough.
Any ideas?
Thanks for any info

Sorry to reply to myself, but I believe the signals around 27245 Mhz USB are JS8Call. I'm running JS8Call at 27245 Mhz USB, with an offset of 2500Hz (variable) and have managed to decode a few of these. So if you're interested - JS8Call seems to be alive and well on the CB channels.

WOW! Great catch! I'll have to download that and try it.

I bet you are hearing AX25 (FM) from Germany.
Looks like there quite a vibrant AX25 revival specifically on those frequencies. For example, this one is on 27.235 FM: https://lk0nod.de/
The stations are numerous and - skip permitting - they appear from time to time mixed with other traditional voice traffic.
