BM-5 Block Diagram

   The BM-5 BandMaster V is a full featured unit that contains a universal band decoder and antenna switch controller. It features five communication channels. All channels are active simultaneously and provide data translation for your station accessories. In other words, if you are using an Icom radio on the CI/V interface the BandMaster V will output 4-bit band data as well as RS-232 data in Yaesu or Kenwood format. In reverse, when using a radio on the RS-232 interface the BandMaster V will out 4-bit band data as well as an Icom CI/V data stream. 

   The USB interface may be connected to your PC for radio control. The USB interface may be connected directly to a Flex SDR with no additional cables or interfaces required.

   The BandMaster V contains a fully bi-directional band data interface.  The band data interface operates in input mode when using band data from a Yaesu or Elecraft radio. When operating in band data mode the BandMaster V will output data on both the CI/V and RS-232 interfaces with the frequency fixed to the middle of the current band. The band data interface operates in output mode when any of the other data interfaces are used for your radio. 

   Configuring the BandMaster V is easily done from the front panel. No PC software is required. Antennas are easily assigned to each band. No diode matrix is needed for antennas used on multiple band. 

   The BandMaster V has 12 relay outputs which can configured in up to 16 different combinations. Any combination may be assigned as the default antenna for each band.
