View source for Motorola MTR2000 Repeater

The '''MTR2000''' is a Motorola repeater rated for 100% duty cycle. What follows is some basic information as I figure out what's what.

The model numbers, e.g., T5544A or T5766A, do not communicate band information! They seem to just tell you that it's an MTR2000.

Also, a lot of people seem to take the front panel off and use the information on the sticker on the left to describe their eBay ads. That's the information on the power supply. Some of the FRUs (Field-Replaceable Units) can be used to figure out the band lacking other indications. What's below is stuff I've gathered from perusing some eBay listings over time; http://www.repeater-builder.com/motorola/mtr2k/mtr2000-frus.html is perhaps the definitive list.

Be aware that there are MTR2000s that shipped with _only_ a receiver, listed as satellite receivers. They look the same and even appear to have the PA heatsink, but with no connector since there's no actual transmitter or PA. The rear label will show only an RX FCC ID, no TX one. T5769A (UHF) is one model number; is that meaningful?

== Bands ==

=== VHF ===

On the VHF side, the FCC type-acceptance ID is the _same_ between the splits. The low-power (132-174) transmitter is ABZ89FC3785; the high-power (132-154 _or_ 150-174) is ABZ89FC3786.

==== FRUs ====
Please note that some FRUs cover the whole bandsplit, but that does _not_ mean the entire repeater does. For example, a 150-174 MHz repeater may have the 132-174 MHz exciter and receiver.

** TRD6431F, TRD6431G, TRD6431J - with preselector
* VHF exciter FRUs:
