II. Microphone Jack Considerations
Two 8-pin mic chassis jacks are included with your “semi-kit,” and most modern
transceivers (Kenwood, late Ten-Tec, Icom, Yaesu, Elecraft, Flex-Radio) will use these
jacks. Older vintage rigs (earlyTen-Tec, Drake TR-5/7, Johnson Ranger, Collins KWS-1,
Heathkit, etc.) typically used either 4-pin or 2-pin connectors. The mic jacks for all of
these vintage rigs also will fit in the 5/8 in. prepunched holes in the front panel, but must
be supplied by the builder.
Some other vintage rigs, for example the Collins “S-Line”, the Drake “B-Line”
and “C-Line,” and the National NCX-5, use 3/16 in. or 1/4 in. microphone plugs whose
mating jacks require a 3/8 in. hole. If you want to use one of these microphone jacks, then
you should use insulating washers (not supplied) to adapt each jack to the 5/8 in. hole in
the StationPro’s front panel. (Insulating washers will minimize hum pickup – see the next
paragraph and
