RF PTT Sense


Charles Scott
 

All:

I've had my LA-1K connected to an IC-7300 for a couple months now and find nothing I don't like or that people who hear me don't like. - Thanks Palstar!

This morning I had a thought to put one of my 4-20W military manpack radios on the amp, but then it struck me that these radios don't have TX contact out. Now you might think that's just a simple thing to bring out a TX line from the radio. It probably is, but we're talking about some completely unmodified and not particularly cheap radios that I'm not inclined to do that to.

I could of course build up an outboard RF sensing to TX out unit (RF VOX) to drive the TX in on the LA-1K. But of course the Amp already senses the RF, as we know. My question then is whether it makes sense to ask Palstar to add an RF VOX feature to the firmware and what the implications of that might be.

Would anyone else like this feature, have any fears, or have a favorite outboard RF sense relay circuit with adjustable drop-out delay they like?
