This is important to you because:

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

DSR's reprogrammed M803:

  • Speech Compression is ENABLED.

  • 154 User Group Channels are programmed with CRUISER-USEFUL station frequency data.

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

 (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.

DSR's Customized User  Group  Database - Up-to-date  SSB & HAM frequencies & NETS .

Amateur/Ham & VFO Modes enabled - Tunes like a regular radio.
