Jim, et al:

I've got a dead Narco VOA4 sitting on the seat in the car. I don't think
it's even worth taking down to the instrument shop (at KAPA) to see about
repairing it, it's so old. I'll probably donate it to the local aviation
school's "museum".

And doing my homework (and I still don't know what I'm doing -- remember,
I do software, not hardware) I know that the TKM nav/com connects nicely to
Narco equipment (e.g. ID 824) but what about to a King? (e.g. KI201)

I'm still seriously considering the RST marker beacon unit, but you need
to understand that I barely know which end of the soldering iron to
hold (and I have the scars to prove it!) It's why I do software....

In Arizona summers, being in air conditioned offices was
much nicer than being in the shop.
