[Elecraft] Diode Matrix for Band Out on K3

[Joe Subich, W4TV]

Ken,

The Band0-Band3 data is identical to Yaesu Band Data for
HF (160-6 meters).  Any of the standard BCD to 1 of 10
or HEX to 1 of 16 decoders will work fine.  If one were
using the K3 to drive a stack of transceivers and wanted
to be particularly clever, it is possible to use two
decoders if they have an enable input and use DIGOUT0
with a pull-up, buffer and inverter to select either HF/6
or transverter (VHF/UHF/SHF) outputs.

73,

    ... Joe, W4TV
