Band Data Output:
The MBD-8F receives the radio information by
CI-V (Icom), or by RS-232, or by BCD
and provides a BCD output for use in external equipment.
Command output for the RS-24 and RS-44
The MBD-8F has the command output to the rotator
switch RS-24 or RS-44. On the front pannel
there are four LED´s to indicate the rotor in use
at the moment. The programming to associate the rotator
to each antenna is one easy job made by the user in a
couple of minutes. This configuration is saved in a not
