"Hi,
I am pondering replacing a Micor (146 mhz} ham repeater with a more
current model. As many already know the receiver in the Micor is
excellent. Could some one dust off a Micor maintenance manual and get
the receiver specs for me. For that matter does anyone have experience
or know of current repeater receivers that match or exceed the Micor
specs?"

You will have a hard time beating a Micor receiver, however, I can
tell you that the Motorola Quantar makes an outstanding ham repeater.
Used ones are becoming affordable but give consideration to the
maintenance. These units are FRU based and exchange assemblies are
expensive.
The IF and demodulation is all done in DSP in the Quantar. The
squelch action is even better than the Micor chip. Interfacing is a
snap - assuming you have the wireline board which hosts the wildcard +
E&M I/O.
Specs: Micor / Quantar
20 dBq: 0.5 uV / 0.35 uV
12 dB SINAD: 0.35 uV / 0.25 uV
IM rejection: 80 dB / 85 dB
Spurious & image: 100 dB / 100 dB
