Motrac? Those are 30-40 years ancient. I used them for boat anchors.
Back then, I preferred GE radios:

Back in the day we were radio techs and weight lifters!

I used both. I had Pre-Progs and Progs. Both were good for keeping warm
and digging out of the snow, but the MHT motracs were extremely easy to
duplex, bullet proof and had excellent audio. With 110 watts VHF and the
optional preamp for .12uv for 20dbq, that radio talked like no other I have
owned before or since, and I could do it parked at a jam packed radio site.
I ran a UHF 35 watt radio, duplexed, to access a high level remote base
system with an autopatch. We had wide area flat rate dialing and I had a
switch on my WE TT pad to key the radio continuously. A resistor across the
relay and a small cavity for the RX and it sounded better than the IMTS
system. I never graduated to Micor for a mobile because it could cost you
$500 just to fill up a 12 channel mobile. I was using a duplexed 73MHT up
to 5 years ago because I always wanted to monitor that frequency and had
little trouble as NCS.

IMNSHO the Micor and MastrII have yet to be improved upon for performance
and practicality for a repeater.

OH - the point was the coupling in the PA tube would allow you to match
directly to 75 ohm.
