Microchipz HC806

This is designed for the PTBM133A4X board found in the HAM Jumbo 3, Concorde 3, Multimode 3 and others

using the 133 board.

​

This will NOT work in the Viking 3.

​

This board is a direct replacement for the HC806 unit and with the only extra connection of 9v supply will replace a failed HC806.

​

This board will also give UK1-40 readout on HIGH band by connecting the 2 connections.

​

This board will also fix the -40 and -80  channel map back to a standard channel map, this is selectable by soldering a link on the rear of the board.
