Off topic microphone

[Gil WA5YKK]

   OMs;

  I've been giving my old Alinco mike a jaundiced look lately, the
remaining part of a HTX-212 rig I got from Rad Shacque many years ago.
The prime question: does anyone have a short answer for me, if this
little electret mike, with up/dwn buttons, keyboard, PTT switch, will
work with my K2? I'm going to take a dare and see if that outfit will
even provide a schematic for the aged little thing, find out what might
or might not work, but I can also use some input from others who might
be a tad more experienced with "hybrid" parts that seem to look viable.

Thanks for any input, and I'm relearning a lot that went foggy on me
with all my projects!

Gil,
this isn't "off topic", you are perfectly ok in my book.

If you can find the wiring diagram for the 212 and match it up with the
K2, I think it will work.

Good luck

Gil,

I am certain that mic *CAN* be made to work, but it will likely require
some re-wiring inside the mic housing itself.  The Up/Dwn buttons and
the keyboard are probably decoded by detecting various voltage levels in
the original design - you would have to convert the Up/Dwn buttons to
simple switches to ground to make use of them with the K2.  The
schematic will be a necessity to determine just what to do with it.

73,
