This is probably true. But Hamtronics and others were
selling turnkey repeater packages long before the surplus
commerical radio conversion market heated up and before
the major LMR Companies started being a lot more friendly
to the Amateur Crowd.
Now everyone is beating up on everyone else for a piece
of the repeater pie. Global economics up against the guy
in his garage or small radio shop back room converting
surplus two way radios.

I have have not found most made for Amateur (factory
built) Radio Repeaters to be splatter generators and
most have pretty good audio. All depends on the model
and generation of production. Original VHF Engineering
2 meter TX strips I have here still have great audio
and still make Part 90 commerical spectral requirements.
Their receiver designs are no longer usable for most
repeater applicataions, but their transmitters work
just fine. One tx strip in a good bud box has been
chugging along since the late 70's.

Might have been specific to the bare bones standard
UHF Micor Mobile we used at the time. The versions
we had with the standard & duplex shield kit had
minimal stray RF problems. We didn't run the mobiles
above 25 watts anyway, the heat sink wasn't rated
for lock to talk operation.
The mentioned micor mobile was a Gov Surplus unit. For
some reason, Motorhead would sell bare bones radios
for low bid prices by removing normal unit installed
parts. We used to joke about the engineers removing
parts until the radio stopped working, then replace
the last part pulled and ship the radio out.
The Mitrek version of this bare bones radio was sold
as a Motrek... same pc board, less parts. "Great taste,
less filling".

Check your mic cord... I do believe they offer a
Part 90 box.

Your above statement reads like you follow "The American
Tower - way of doing business". Might be prudent to
actually source a problem before one points a finger.
