Larry - I've taken 450-470 MHz Micor 25 watt mobiles & ran them on
only the pre-driver to get about 9 watts out (I bypassed the rest of the PA
deck). I also had to bypass the power control board to make it work reliably.

That was a good point out, never gave that a thought, so now I will just build 4 cor circuits to make them work, that will be easier than trying to make 5 volts jump to 8, can just make a simple 10 or 8 volt COR circuit. Glad this came back up a 2nd time around.

Although I haven't experimented with the 406-420 Micors, I have

all of the PA deck micro-strip amplifiers are 50 ohm impedance in

You still have to add COR to them. And the p

I have a couple of 100-Watt, 406-420 MHz MICOR Mobile radios. I picked them up
at Dayton a few years ago since they were very inexpensive, and hoped that I
could use them as some link radios. I'd like to find out how to use just the

As the other guy mentioned... just set it to zero.
Most TV Station feeds want the unit 100% operational
(ie on the air full duplex) at least 20 min before
the broadcast and at least another few minutes to
knock down after the remote is done.
It's not uncommon to see 1/2 hour up before times

Yep.
The other reason not to buy expensive crystals is if you are trying to find a
clear channel for your repeater to operate on. In southern California, the
70cm coordinating body is pretty close to ineffectual. If you have to change
frequencies 2-3 times to resolve interference issues it can

Guess I did not see that post about how I can't afford to put a repeater on
the air! Funny, I have three on my 500 foot tower now and none of the

if you can. RFS has a few nice looking UHF antennas.
