This page is a collection of info on the MTR2000 and possibly MTR3000 repeaters.

The MTR2000 was Motorola's mid range repeater in the 2000's, designed to do analog and sit between the two mobiles and the Quantar at the high end. It's basically a quantar-lite, as it runs the same RTOS, pSOS+ and runs on the same Microprocessor, but an integrated version of it and the DSP chip.

The MTR has a depot manual, but it's not avialble AFIK. IF you have one, please tell me, I will happyily send you a shipping label, have it scanned professionally and send it back all at my cost.

The part number for the Depot Manual are 6881096E40, and 6881096E35, VHF/UHF respectively.

It's likely the RF circuits are identical (or close enough) between the Quantar and the MTR. For Example, the Power Amp uses the same pallet amplifiers/LPF/isolators as the Quantar does.
