I have something to share…It is on every night on 5.620 MHz around 010 UTC some folks talking language unknown..It goes on most of the night..This is an aero frequency but these folks are there every night. Hope to find out more. Maybe fishing vessels or something else–? It is these mysteries that make this hobby fun!
My schedule as of late has not allowed dedicated listening time on this frequency. I would certainly suspect fishing vessel communications, but can’t confirm.
Post readers: can you help Gene identify this over-the-air chatter? Please comment!
