I'm going to build an interface box today for ptt, cw keying,
and dvk triggers. I see that Tree recommends relays for the
first two. Are these 5vdc or 12 vdc? I guess I could get in
there with a voltmeter, but maybe somebody knows offhand and can
save me a trip into the rat's nest under the table.

I'm going to try to use the dvk triggers to pick up relays
to trigger the internal dvk in the ts-850. Are these 5 or
12vdc, and is the pulse duration long enough to pick up a
relay momentarily? I guess the common return line for the
dvk triggers is pin 18 (gnd)? Or is it pin 1 (strobe)?

Thanks in advance for saving me a bunch of experimenting under the
