I'd like to wire the PA horn output from a VHF to a trigger a
tradition non-PA horn. I would think that I could use a relay for
this but could use some guidance with respect to selecting and wiring
the right relay here.


Are you talking like a car horn or some kind of speaker.....??

If you want the radio to honk a horn or beeper when a signal breaks the
squelch, you need a cheap SCR (if you want it to latch) or a power
transistor, if you want it to beep with the noise and shut off when it
resquelches

Tell me more about what you're looking for. Non-PA horn doesn't say
much....

Sorry-- to clarify-- I would like to use the foghorn function of the
vhf to trigger a traditional (read: non-speaker) 12v horn.
