MTR 2000 Master Oscillator.

Post by Bruce1807 »

I have a VHF MTR2000 that will not tune on frequency.
It is off by about 5khz on tx and a bit deaf.
Is the main oscillator on the control board or on the exiter module.
I need to order the right one.

CLN1201A Station Control Module

Hello Bruce,

You pretty much troubleshot the oscillator reference down to the correct area.

Here’s the component that you’ve requested (IC) U5502 Part # 5184726T02 Reference OSC Module on the Station Control Module. The CLN1201A SCM feeds a 2.1 MHz signal to both the Exciter and the Receiver. Personally I’d order a CLN1201A FRU, swap the SCM and sent the defective one into the /\/\ / CTDI Infrastructures Depot Operations in Elgin, IL for a Flat Rate Repair.

I tend to agree as it is only $936 from MOL.
I dont have the depot manuals which I will order at the same time
That why I wanted to know wether or not to order the controller or the exiter. I sort of guessed the controller unless the rxer had its own on board one but then if so there would be an alignment sheet.

I may have a 800Mhz controller i can drag out.
is the firmware plug in like the quantars or does it have to uploaded.

basicly can I use my 800Mhz controller in my VHF station.
I wonder if I just try and dump the codeplug into it.

Hi Bruce,

I don't recall any differences between 150, 450, 800 or 900 Mhz Station Control Modules. There all plain Jane generic modules, at least they were in /\/\ factory's final test area 2-1/2 years ago. The only difference would be the software programming configuration. Besides you'll be time ahead by swapping your own spare.
