Louis,
My TX-RX catalog provides the following information:
89 = Preselector
88 = 890-960 MHz
95482 = Not listed, probably a custom product

Don't forget to enable pin 10 as ignition sense in the software, for both
radios.

the
receiver sensitivity, so I simply assumed 0.3 uV. If you're willing to
accept some desense, you can get by with less isolation. I consider 80 dB
of duplexer isolation to be a minimum, and prefer to achieve 95 dB or more
for most repeaters.

Dave,
The CW ID deviation adjustment is step 26 in the service manual alignment
section. It is adjusted with your PC when running FPU KPG-91D software.
The default setting is +/- 2 kHz, but it can be set to any value you wish.

About the only device that has a sharp enough response is a front-end
crystal filter. While very effective, they are lossy and cost between $350
and $500 each. Here is more info:

Chris,
This question comes up quite often, but I will repeat the standard response.

of desense- and that means 95 to 100 dB of isolation with most
practical repeaters. Choose wisely...

that is in service with many Public Safety agencies in
Central California, but it does require a power amplifier. A TKR840 with a
TPL PA is hard to beat for durability. Needless to say, the TKR850 and the
TKR840 are light years apart in quality and performance.

please educate me: What is an MCR-2000 repeater, and who makes it?
