DSR's reprogrammed M803:

  •  Speech Compression is ENABLED. (Increases "talk power").

  •  154 User Group Channels are programmed with Up-to-date CRUISER-USEFUL station frequencies.

  •  Configuration/Settings set to work properly with Pactor Modem.

Out-of-the-box M803 Default:

  •  Speech compression is DISABLED.

  •  From a cruising sailor's standpoint, many of the factory-loaded frequencies in the  User Channel Group are NOT USEFUL TO CRUISERS.

  •  Only 124 of 160 User Group Channels contain station frequency date. 36 channels are empty.

 (By definition , making these changes  means we functionally check-out your radio before shipping).

Speech Compression enabled - Increases your  "talk power".  Makes your signal louder & clearer.
