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: Repeater-Builder@yahoogroups.com [mailto:repeater-buil...@yahoogroups.com] On Behalf Of NORM KNAPP Sent: Monday, November 16, 2009 9:08 AM To: Repeater-Builder@yahoogroups.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. Thanks es 73 Norm
