The MBD-62 is an intelligent controller compatible with all antenna switches manufactured by Hamplus and a few other manufacturers. It has two band decoders to receive the information coming from the two radio equipment connected to it. In addition to antenna switching, the MBD-62 also offers sixteen GPOs (General Purpose Output), eight for each radio, which can be used to control two band pass filters, or command the tuning box of shortened antennas with high Q coils, or are simply triggered when a desired frequency or band is detected. There are four ways in which antennas can be selected; 1) manually by the front panel of the MBD-62, 2) manually by changing the frequency or band on the front panel of the transceiver, 3) automatically by frequency or band change by the remotely controlled transceiver, or 4) automatically by a connected personal computer via RS-232 serial port or LAN port with the MBD-62.

On the front panel there is a set of two lines of six illuminated push buttons for manual selection of antennas, one LED for each radio to indicate when transmitting, one LED for each radio indicates that the MBD-62 is in "Split Antenna" mode, and one LED to indicate when the MBD-62 is energized.

The MBD-62 receives from the transceiver the power supply (13.8VDC), the "Send" line and the information about the band in use. The MBD-62 controller recognizes the following radios:

1- CI-V (Icom)
2- BCD (Yaesu and Elecraft)
3- RS-232 (Kenwood, Icom and Elecraft)

Frequency Driven GPO

The MBD-62 provides up to eigth tuning points for automatically controlling shortened antennas with high Q coils. The tuning points are easily found by the operator using the radio and push buttons

Band Pass Filter Drive

The MBD-62 only needs one cable to automatically control most of the band pass filters on the market. Can be set to Active High (+12V) or Active Low (Gnd).
