Hello All!
Just picked up a mint condition Universal M-400 decoder for a friend. Paid $60 with the manual and original wall wart. For those not familiar with it, here is a link for more info: http://www.universal-radio.com/catalog/decoders/m400.html
He is going to use it for acars. He asked about the other modes that the unit is capable of decoding. Now, I know about pocsag and golay digital paging modes. My question is this, is this type of decoder any good for HF or shortwave data decoding given todays' modern digital modes? Any of these modes still in use? This is an area I am not really familiar with and would like some direction on this to guide my friend.
