MTR Repeater
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.

firmware update notes
I'm not 100% sure on this, but I belive the firmware is locked to the base station from motorola using the .enc file that comes with it. Anyone have info on this?
I took the binary image from the 28f800 and did the following to make an image that can be flashed to the station with the OUTLAW program.
srec_cat 28F800\ image\ for\ MTR2000.bin -binary -offset -0x4000 -o 28F800MTR2000.srec -Motorola 32 -address-length=3 -line-length=270 -data-only
This should at least replicate what's in memory. Likely can take the raw uncompressed firmware file from the update and add it into the end of it.
the .CMP file is nothing other than LZSS compressed data. Specifically it's the SZDD file format, and COMPRESS.EXE and EXPAND.EXE from DOS can expand the file directly. The header of the CMP file is "0x535A444488F02733" or "SZDD..'3" ascii, hence the SZDD name.

The MTR has a depot manual, but it's not available AFIK. IF you have one, please tell me, I will happily 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 68P81096E40, and 68P81096E35, 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.
