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.

Re: [Repeater-Builder] 50 Watt Repeater
Icom Systems group sells a version of the FR3000 with a 100w amp and additional power supply, if you are looking for off the shelf.. that is how you get 50+ watts at 100% duty cycle... Most folks opt to go to less than 100% duty cycle to keep from doubling the cost... but if you really need 50+w all day all night all nice. you need a station with an amp rated at that Probably still cheaper than buying a Harris or Motorola 100w station ie Mastr III or Quantar or similar ... For public Safety I would still look at these latter two choices.. as their 100% track record is readily duplicate-able. I believe Kenwood sells a similar arrangement... The little desktop size repeater just do not have the heatsink and cooling to do 50W @100% without some form of additional external amp... It is about heat dissipation.. 50watts is easy.. cooling 24x7 in any reasonable environment is a little trickier... While you can force anything to do 100% that does not mean it was engineered for it..or suggested.. :-) That engineering generally costs... or if it is for amateur.. Build it :-) Doug KD8B At 02:10 PM 11/16/2009, you wrote: Any suggestions on a 50 watt repeater to buy?

Hi Eric and thanks for the input. I will read the repeater out here in the next day or so. That should give me the model info.

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-Builder%40yahoogroups.com [mailto:Repeater-Builder@yahoogroups.com mailto:Repeater-Builder%40yahoogroups.com ] On Behalf Of NORM KNAPP Sent: Monday, November 16, 2009 9:08 AM To: Repeater-Builder@yahoogroups.com mailto:Repeater-Builder%40yahoogroups.com Subject: [Repeater-Builder] Mtr-2000 for 2m use.

If I might add my 2 cents here-I have now narrow banded a number of Mastr II receivers, all high band, using the kit from Com Specs, it works Great HOWEVER, the receivers all have a problem with the squelch threshold and there is a lot of popping going on-setting the squelch tighter does no good-the issue seems to be that the noise settings for the Mastr II-we have tried many different fixes including adding a Mot. Squelch, and adjusting the hidden magic pot-to no avail-even sitting on the bench with no signal applied they are very noisy-and while the sensitivity measures about the same as before, the performance is not.

skipp025 wrote: What's sad is how much will likely go in the dumpster instead into some deserving ham's hands ;c} Or made available on/to the surplus market. Actually, there is still a legal question as to whether equipment that was not type-accepted for narrow-band originally will still be legal if the transmitter is narrow-banded, ie, deviation turned down. The FCC has yet to clarify much of anything like that. A big can of worms and there seems to be a lot of people on many groups who live to post various FCC rules along with their interpretations. Bores me to tears to try and read the legalese these folks spout. Some key points if I may... The narrow band physical mod is to the receiver. The transmitter is not a mod, but typically a standard deviation and audio level adjustment. It is the responsibility of the License Holder to ensure the emissions are legal. I personally have been told by more than one FCC Field Agent and a former Office Chief... (still working at the FCC in a higher capacity) they are not going to get excited about properly upgraded equipment properly running within the limits of the license requirements. The above has proven to be the case the few times I've had site interactions with the FCC. I've never seen a Field Agent walking around with a type acceptance list or computer doing said look-ups. s. Well, they can do that, but it needs to be clarified whether just turning down the deviation is enough. Many knowledgeable engineering types are saying that the filtering (splatter filters, etc) are not adequate in this case. And I can see that they are likely right.
RE: [Repeater-Builder] 50 Watt Repeater
A 40-watt Motorola MTR2000 is continuous duty, and darn near bulletproof. I have one such repeater that is used to broadcast Amateur Radio News and another bulletin service, and it stays key-down for almost an hour at full power, and it barely gets warm. I doubt that any repeater users can detect the difference between 40 watts and 50 watts. Remember, buying quality only hurts once! 73, Eric Lemmon WB6FLY At 02:10 PM 11/16/2009, you wrote: Any suggestions on a 50 watt repeater to buy?

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. Hi Eric and thanks for the input. I will read the repeater out here in the next day or so. That should give me the model info. The reason I brought up the external preselector is that every other MTR-2000s I have seen have the preselector bolted on to the rear of it.

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.

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.
