Re: [Repeater-Builder] Mtr-2000 for 2m use.
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?

RE: [Repeater-Builder] Mtr-2000 for 2m use.
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. 73, Eric Lemmon WB6FLY -Original Message- From: Repeater-Builder@yahoogroups.com [mailto:repeater-buil...@yahoogroups.com] On Behalf Of NORM KNAPP Sent: Monday, November 23, 2009 3:04 PM To: Repeater-Builder@yahoogroups.com Subject: Re: [Repeater-Builder] Mtr-2000 for 2m use.

Re: [Repeater-Builder] Mtr-2000 for 2m use.
Norm, Assuming that your radio is VHF (what were the existing operating frequencies?); the VHF radio comes in two bandsplits in the high power VHF station. There is no way to change one bandsplit to the other. I was involved with a project where incorrect frequencies were entered by someone doing an order resulting in a range 1 receiver and a range two transmitter. The radio ended up being sent back to the factory and replaced by an entirely new unit to correct the problem. The best way to proceed at this point is to have someone with the proper RSS read the radio and give you a printout of the existing codeplug.

RE: [Repeater-Builder] Mtr-2000 for 2m use.
Norm, You're welcome! You don't need to read the radio to get the necessary information- just look for the small paper labels on the rear of the power amplifier, and decode the numbers with the chart I mentioned. Regarding the preselectors, I never could figure out why some folks always specified an external preselector, even without any compelling technical reason. I can see using the preselector as a precaution only when several base stations are co-located, but the standard internal preselector used in the MTR2000 works just fine in a repeater. I have eight MTR2000 repeaters in service now, both commercial and Amateur, and none of them have or need an external preselector. 73, Eric Lemmon WB6FLY -Original Message- From: Repeater-Builder@yahoogroups.com [mailto:repeater-buil...@yahoogroups.com] On Behalf Of NORM KNAPP Sent: Tuesday, November 17, 2009 6:40 AM To: Repeater-Builder@yahoogroups.com Subject: Re: [Repeater-Builder] Mtr-2000 for 2m use.

Re: [Repeater-Builder] Mtr-2000 for 2m use.
Well, the MTR2000 in VHF came primarily in two flavors, 132-174 MHz 40 watt, and 150-174 MHz 100 watt. The 150-174 MHz 100 watt unit will not tune down to 2 meter ham frequencies. The easy way to tell the two apart is looking for fans on the PA and power supply. If you have fans, you have a 100 watt unit. No fans or just a fan on the power supply, you'll have a 40 watt unit.

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
