Listening via the G8JNJ SDR at 1750 UTC tune-in time. Numerous transmitters active on 31.325 MHz, various signal strengths. Tell-tale polytone data signal
In addition to 31325 kHz / 31.3250 MHz, EPAR data bursts are coming in on:
31.4375 MHz
31.6375 MHz
31.6875 MHz
31.9250 MHz
31.9750 MHz
However 31.325 FM is the most active frequency, at least at the moment. It's been a while since I've heard the EPAR system. Sort of a de facto beacon.
