I write a GNURADIO block to decode psk beacon (it can decode K,L,M,N block). It need a GNU demodulator (costas loop and clock sync) .
If someone is interested I can provide the decoding block.
It will be much more interesting if some additional information should be added to the beacon: telemetry don't make sense (due to IP regarding satellite functionality) but information regading dx expedition,special call,ecc can be useful.
