Norm, It's not that simple. All of the MTR2000 modules, including the PA, are controlled digitally over the SPI bus. The station control module (SCM) polls all of the modules during power-up self test to ensure that the station configuration has not changed and all modules are working. You must connect a low-split 100 watt PA, or a 40 watt PA, before you can program anything below 150 MHz.

Ok. I read the MTR2000 with my laptop. Sure enough, it has the 150-174mhz 100w pa. However, I noticed in the software that the exciter is listed as 132-174mhz AND the PA is an option. Does this mean I could disable the PA and run an external PA, such as a MASTR II or MSR2000?

Norm, None of the numbers you provided identifies the band or power of your MTR2000. It happens that the MTR2000 contains an internal preselector, but that fact is irrelevant to 2m operation- the duplexer will allow any VHF MTR2000 to work on 2m. All MTR2000 stations purchased through retail channels carry the model number T5766, regardless of band or power. First of all, do you know for certain that the station is VHF? If so, does the station have fans in the heat sinks? If so, then it is a 100-watt class unit. There are two models of 100 watt VHF MTR2000 stations: One will operate only in the band 132-154 MHz, and the other will operate only in the band 150-174 MHz. The latter unit cannot be made or modified to work at 2m. To help identify your MTR2000, go to this link to get a list of modules to identify exactly what you have: <www.repeater-builder.com/motorola/mtr2k/mtr-2000-frus.html> and some additional info is here: <www.repeater-builder.com/motorola/mtr2k/mtr-2000-followup.html> 73, Eric Lemmon WB6FLY -----Original Message----- From: [email protected] <mailto:Repeater-Builder%40yahoogroups.com> <mailto:Repeater-Builder%40yahoogroups.com> [mailto:[email protected] <mailto:Repeater-Builder%40yahoogroups.com> <mailto:Repeater-Builder%40yahoogroups.com> ] On Behalf Of NORM KNAPP Sent: Monday, November 16, 2009 9:08 AM To: [email protected] <mailto:Repeater-Builder%40yahoogroups.com> <mailto:Repeater-Builder%40yahoogroups.com> Subject: [Repeater-Builder] Mtr-2000 for 2m use. I recently obtained a Motorola MTR-2000. It took a lightning hit to the tone remote board, but the repeat functions fine. Upon close inspection, it appears this unit was originally used as a base station before it was a repeater by evidence of ant rel installed. Also it does not have a preselector on the rear. My question is, will this thing work on 2m and will I have to come up with a motorola preselector to use with a 600khz split? S/N 474CZT03xx F.O.: 0960-5003-40067 model no: T5766A type no: FO306B.
