How to decode the sound of HITSAT FM on MixW2
I was successful in the decode the header of HITSAT FM 437.425MHz packet data. These signals were switched on ONLY in the range of Japan. And these 1k2 AFSK (FM 437.425 MHz) be able to decode by modem of IC FX614, becauce NOT AX.25 (not NRZ-NRZI). I was successful in the decode of the header "JR8YJT" of these FM data by using a soundcard program MixW2 (ver2.17).
