I drooled about VOX when I was a kid, never thinking I'd 
never have time to to build it. Then 20yrs later, due to 
transistors, printed circuits and economies of scale, you 
could buy a handheld with VOX. I thought I'd died and gone 
to heaven. It took about 10mins to find that when it worked 
perfectly, it was useless. You'd only have to say "hmm" to 
yourself, or scratch your face and the transmitter would be 
on for the next 30secs. If when you were actually 
transmitting, you paused to think, the transmitter would 
drop out without you indicating to the other person that you 
were handing it over to them. When you're finished your 
over, you can't just hand over to the other guy, you have to 
wait for your machine to time out. You can tell a person 
with VOX - they don't pause between sentences and keep 
talking. They sound like they have someone with a gun at 
their head that will go off if they stop talking.

You want something that turns the transmitter on when you 
want it to go on and turns it off when you want it to go 
off. VOX turns the transmitter on when there's noise and off 
when there's no noise. VOX is not what you want. What you 
want is a mike switch. It's already been invented.

When automatic light switches arrived, I installed one in my 
study. If I was working without standing up and moving 
around for 5mins, the lights would go off. I'd have to wave 
my hands for about 30sec before the lights would come on. 
I'd have to do the same thing 5 mins later. I pulled it out 
and replaced it with a regular switch that turns the lights 
on when I want them on and turns them off when I want them 
off.
