[Repeater-Builder] Mtr-2000 for 2m use.
I recently obtained a Motorola MTR-2000. It took a lightening 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.

It is currently on 147.280/147.880 (crystals included). It has been sitting in my shop for 10+ years, so it's time to let someone else have some fun. $50 or B.O.

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.

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

Re: [Repeater-Builder] Micor repeater audio
I stand corrected. I just checked mine on the bench. Injected signal from my audio generator into the Exciter (pin 24 on the TX interconnect board). Set the output of the generator to acheive 3k deviation at 1k. Then checked the 1/3 octaves from 160 to 6300. I posted the graph in the files section of the group, but I found the peak at 1600Hz. I suppose I could do this again into the PL input to go around the stock audio processing, but this is the way I am going to use it.. However, I believe the audio tailoring I am hearing is actually caused on the RX side of things. The other file I posted in the group a few weeks ago (When I was checking adm vs non-adm) was measued by outputting a constant 3k dev on the service monitor at multiple audio frequencies and measuring the audio input going into the exciter thru the RX and 7K controller with an AC voltmeter. You will see on that graph there is most definatly a bump at 200-400Hz. I can double check, but the last time i swept a straight 7k it was pretty flat in audio response, so the tailoring must be caused by the RX or the AS board and the PL filtering (Which I am using). I'm sure Kevin or someone else out here smarter than me has a logical explainationI'll wait to read it.

I will measure it exactly tommorow and post my findings.

I've noticed that the audio is lacking in lows its not tinny but its not what I would call normal audio from a Micor. The audio levels and on frequency adjustments have made and to seem to be on the money. This is an unmodified repeater station using stock cards and no controller. The receiver is stock and the frequency has been changed to the 440mhz band. The audio coming out of the receiver has fine audio quality. Just looking for your thoughts or ideas. Thanks for your input Mike I don't have a real answer for you, but it's interesting that I have had the opposite experience with the two most recent Micor UHF stations I put on-line. Both have a peak very near to 400 Hz, and roll off several dB/octave above that. Setting for 3 in/3 out @ 1KHz, I get abt 4 out @ 400 hz, and abt, oh, 1.5 or so at 3K. Anyone else noticed a peak around 400 Hz on a UHF Micor station? Yahoo! Groups Links repeater-builder-fullfeatu...@yahoogroups.com Yahoo! Groups Links repeater-builder-fullfeatu...@yahoogroups.com
[Repeater-Builder] 50 Watt Repeater
Any suggestions on a 50 watt repeater to buy? I've been looking around and keep looking at the Icom FR3000, I know there are others but I am having trouble finding a 50 Watt Continous duty... The Icom FR5000 is 25W at 100% duty cycle but is considered a 50 watt repeater.
