Can I use Micor PA module on MSR2000, if yes how I can do?
What freq. range on Micor PA and part number?
Micor base & MSR2000

...
yes, you can. the local 2m machine here is using a micor PA on an MSR chassis.... as far as details... can't help ya there.

VHF Micor vs. MSR Power Amp
Yes you can but keep in mind there are some minor differences between the Micor Exciter and MSR2000 Exciter. The Micor Exciter feeds a Low Pass Filter allowing 500~750 milliwatts of RF Drive to the BNC Input Port on the Micor Power Amplifier.
On the MSR2000 Exciter's RF Output, there's 1.5 watts RF Driving the same BNC Input Port on the MSR Power Amplifier but these amplifiers also include a small Exciter Voltage Regulator Board TRN5585A that allows you to reduce the Exciter's RF Drive to 500~750 milliwatts so the signal does not over drive the RF Power Amplifier burning up the first RF Transistor stage.
There's another way to reduce the MSR2000 Exciter Output 1.5 watts RF Drive by purchasing a commercial 3 dB 2 Watts Attenuator w/BNC connectors on each end and installing it on the MICOR's Input RF Drive connector on the Power Amplifier itself.
MICOR<=>MSR2000 (Continuous Duty) Power Amplifier Kits:
TLD 1692 TLD2601 (132-150.8 MHz) TLD 5952 PA Board
TLD 1693 TLD2602 (150.8-162 MHz) TLD 5953 PA Board
TLD 1694 TLD2603 (162.0-174 MHz) TLD 5954 PA Board
