The FSK part is undecodable nowadays. However, it can be decoded into binary data with a raw FSK decoder such as fldigi.

HM02 runs only one schedule, everyday at 4:40 UTC on 7351 CW.

The believed origin is the Russian naval base in Kaliningrad, the same base that ran S21 and M45 in the past, due to the 3-zero ending present in the format.
