RE: [Repeater-Builder] Re: Motorola MTR2000 Question
Here's a quick and simple way to tell if there's another repeater some where and what freqs. the current one is on. Just turn off the ones you've found and see what radios no longer bring up the repeater. Then you'll know if it's bus, police, or maintenance.

Its just know a matter of cat and mouse on the third repeater location. As there is no one that works here anymore that knows where the radios are all located expect the 2 at the high school football field. In fact the bus repeater as listed on its license is supposed to be located right in the middle of the intersection of a state highway and a US highway that runs through our town, while the GPS listed on the same license shows it to be about 20 miles south of that location in the middle of a cow pasture. Will keep seeking, thanks for the help and input. Chris KE5IGO

Re: [Repeater-Builder] Re: Motorola MTR2000 Question
Hello Chris: Why can't the School District contact the company/person that services the equipment? Ask them for the frequency information and equipment location? There must be some record of payment for service that will identify who the district has been dealing with in the past. I haven't been involved in 2 way commercial service for many years but, back in my day's every customer was required to have his equipment checked every year for proper frequency. It would be noted in the station log and equipment service tag/ID tag that accompanied every unit and would be a paper trail to who the district was dealing with.

Another possible trick is, if your control point (listed on the license) is a remote, there will be a dedicated phone line going from it to the repeater site. Call the phone company see where their records show the other end George, KA3HSW / WQGJ413
RE: [Repeater-Builder] Re: Motorola MTR2000 Question
Both 158.385 MHz and 173.325 MHz are independent frequencies in the Industrial/Business Pool that can be used for either base or mobile operation. Neither frequency is paired with another, so the separation between them is irrelevant. However, this wide spacing will lend itself to a two-antenna installation. With only 34 dB of isolation needed, this could be met with about 10 feet of vertical spacing. In addition, neither frequency has any limitations or coordination body associated with them, so the licensed users are free to apply them as they wish. In this particular case, any questions about licensing or location of transmitters should be directed to whatever person or company is shown as the Contact on the license, which is: Comtex Communications Pat L Gardenhire PO Box 977 601 Ferris Avenue WAXAHACHIE, TX 75165 972-938-1980 73, Eric Lemmon WB6FLY -Original Message- From: Repeater-Builder@yahoogroups.com [mailto:repeater-buil...@yahoogroups.com] On Behalf Of NORM KNAPP Sent: Friday, August 14, 2009 3:16 AM To: Repeater-Builder@yahoogroups.com Subject: Re: [Repeater-Builder] Re: Motorola MTR2000 Question HEy, Is it just me, or do those vhf frequencies seem a bit odd.

I didn't know there were bussiness freqs in the 173mhz range. If we had applied for a repeater pair for bussiness use and they had sent back 158 something and 173 something, I would have thougth they hit a 7 instead of a 5 and it should have been 153 something instead.

You didn't mention the maintenance dept. having their own channel. If buses are using your channel (45x.750) then the repeater is likely at a higher location so it can better cover the area.

Re: [Repeater-Builder] Re: Motorola MTR2000 Question
Monitor the frequency on your department's radios to see if you hear anyone else on it (like the users of the '451.725' repeater). Second, you can monitor the power of the '451.725' repeater and see if it keys up when you key up on your radios. If it does, it is mismarked or the frequency was changed (very common if interference showed up on the original frequency). You didn't say who the user was supposed to be of the '451.725' repeater. If yours is not at the site (and another test you can do is unplug the '451.725' repeater and see if your radios 'go dead' - again indicating that the labelled frequency is wrong), then you will have to try to find someone to DF your repeater's location. It's easy to do if you have the right equipment. Joe M. Christopher Hodgdon wrote: I wish I had a picture of the repeater house.

I know, I am pushing them to get it updated. But that is another story all together. I do have access to a radio house located at our high school football field and it has two MTR2000 in it, plus two different antennas. One connected to one radio and one connected to the other. One radio is marked with the description of KISD PD, which is our police department for the district and has the following frequency pair listed on it: VHF: RX 173.325 DPL 331 and TX 158.385 DPL 331 The other radio is marked the following: UHF: 451.725 / 456.725 There is no documentation with this equipment, the person incharge of them originally left the district some years ago and no one knows anything about them, expect where they are located, as far as these two boxes go and what frequencies that have listed. Which brings me back to our department, we can find out repeater located anywhere physcially. Our repeater pair is listed as: UHF: 451.750 / 456.750 That is according to FCC, repeater listing and other information I have been able to obtain and by listening to it on a UHF amateur radio to see which frequency they were on. That being said, it is possible that the MTR2000 that is marked with the one UHF frequency, might actually have both pairs programmed into it, but only one can run at a time, right? Is there a way to find out if there is more than one frequency is programmed into the unit and if so, how might we go about that? Another reason I am asking is that we might be upgrading our system in the very near future and I might be able to get my hands on these repeaters. Thanks in advance. --- In Repeater-Builder@yahoogroups.com, Brian Raker brian.raker@ wrote: The radio can be programmed for multiple frequency pairs.

This could be for either amateur operation or commercial operation, but it relates to the repeater itself. Can a Motorola MTR2000 setup on UHF be setup to function as a repeater on more than one pair of frequencies? I know looking at the brochure on

Still, I would check both of those locations - it could be at or near one of them! Joe M.
