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.

Re: [Repeater-Builder] Re: Motorola MTR2000 Question
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.

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
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.

Re: [Repeater-Builder] Re: Motorola MTR2000 Question
Here is the real question. What map datum was used for the GPS cordiantes? That may show where the descrepancy is in location. Chris, does the bus repeater cover a larger area than the PD or Maintanance repeaters? If so it will proably be located on a tower somewhere. If so there may be a utility bill or ret bill that is paid by the district office on it. This may take some research working with the person who pays the bills. Also the Direction finding should not be that hard, the biggest challange that you will have is aquiring the UHF directional antenna. It does not have to be a comercial antenna for what you are trying to do, perhaps one of the radio shops you are currently working with has one they would be willing ot loan you. >From what I can tell you are in North East Texas so some of the people around >there should be able to help.

There are a few odd Land Mobile frequencies in the 170 range. That actually looks more like a business pair than a PD pair, but I'm sure the school qualifies as a business, too (everyone does).

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.

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.

RE: [Repeater-Builder] Re: Motorola MTR2000 Question
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. If you've exhausted all available records, can't contact the previous tech, and can't find a dealer that knows where your repeater is then I'd suggest a good ol' fashioned transmitter hunt. Do you have any amateurs in your area that are up to the task?

RE: [Repeater-Builder] Re: Motorola MTR2000 Question
The UHF repeater is likely mismarked or the frequency info you obtained for your school's license is inaccurate. The UHF repeater is likely the school's repeater. As mentioned earlier the MTR2000 is a multi-channel radio but can only repeat on the channel it is left on. Recommend you find a dealer or tech experienced with the MTR and who has the software necessary to configure it. Have them download its codeplug. Recommend you do the same with your school radios. A comparison of the data will likely answer a lot.

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.

For all intents, these radios are both hardset to the freqs they are programmed to, and apparently currently operating 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? > Possible.

RVN4148, Motorola's RSS/CPP for the MTR2000. Also, the interface cable is 30-82056X02, RJ45 - DB9 serial interface. > Thanks in advance.
