Members of the AZ GMRS Repeater Club will be wheeling their first of many to come Off-Road Trail Run Thursday, December 19, 2024, in the Area of Indian Fort, in the Table Mesa Recreation Area, off of Interstate 17, north of Phoenix, between Black Canyon City and Anthem. The run is not exclusive to just Jeeps. The run is open to any vehicle that is conducive for off-road adventuring. The Trail Comm. Channel will be 462.700 (GMRS 21) with 250.3 Hz, (CTCSS Programming Code 38 for most radios). The group will stop along the trail for lunch.

You're a member of a Emergency Management Team using a Cheap Chinese Radio POS? I hope that this Emrrgency Management Team is not affiliated with any Public Safety Entity.

The Club believes the jammer was not a club member and probably not aware that the PT-T ID is needed for access because the MDC squawk is not repeated and that information was only provided to members through the website members only portion of the website and only the member can view their respective PT-T ID number. There hasn't been a problem since or at least no one has said anything if it has continued.

I don't know those details. About a year ago when the PT-T ID was implemented, the repeater owner did change the input Tone and just recently, the input Tone was changed again. The MDC squawk does not repeat. I would think if the jammer wants to decipher a PT-T ID, he would need to be close or at a high elevation point to someone transmitting the ID. The repeater is not near a large population center but does have a large coverage area footprint.

The members with non-compatible radios had to buy a compatible radio in order to have access. The repeater owner was having a problem with a constant jammer so he took action to eliminate the problem by controlling who has access.

They did have them back in the ASP days when they were ASP. They were cellular look-likes and they had them in the VHF, UHF, and of course the 800 bands. Those were the days when cellular was only 800 Megs.

One of my radio clubs in Arizona has issued every member a personal PT-T ID number for members only to have access to one of the Club's repeaters sites. The PT-T ID must be sent with the MDC signaling. Without the proper ID, the repeater will not open up.

Laird does not have a Glass-Mount antenna

I have very good luck with a Larsen Glass-Mount antenna. My VSWR on 462 megs is about 1.2:1 and 1.6:1 on 467 megs. https://www.arcantenna.com/products/pulse-larsen-kg450udpl-glass-mounted-whip-antenna

Who ever Midland has producing their antennae does a great job in producing a good antennae with good VSWRs on GMRS freqs. Unfortunately, the operating band range is very narrow and that is why they work great on GMRS freqs, if you have a good groundplane. And they do not require any tuning which is a good thing for a majority of the GMRS users. It is a great turn-key solution for most beginning GMRS users.

You need to ascertain the tuned center frequency of the Antenna. Your antenna requires tuning. If your VSWR is 1.2 at 462 Megs and 1.8 at 467 megs it is obviously that your antenna needs to be snipped some more if your desire is only talk to repeaters. If you desire to transmit to both mobiles and repeaters you might want to consider tuning for 465 megs.

Did anyone verify to see it the repeaters are owned by the same person? If so, the two could be configured in a true simulcast controlled system with voting receivers.

Why would it need to be Chirp compatible when the radio is pre-programmed with the five FCC allocated MURS channels that are compatible with other radios with the MURS channels?

That is a "Less Than An Accurate" statement. You'll need to show me any where in Part 95, subpart J, that your statement is accurate insofar as the limitation to only handheld transmitters and not mobile units, and the restriction/limitation on the effective range?

Your best bet is get a Business Radio License in the Club's name and use the Part 90.35 freqs. You might want to consider both VHF and UHF itinerant freqs for your license to avoid any frequency coordination. It is my understanding that the freq. coordinators have been reluctant to approve any applications for Statewide use because the itinerant freqs can be used for that purpose. Also, by rule, the UHF itinerant freqs are limited to 6 watts whereas with the VHF itinerants they can be 50 watts with the exception of a couple of the itinerants that are limited to 35 watts, which is no big deal. You can file for the new license on-line, it's pretty easy and I would submit your license for both analog and digital emissions for each freq and for Nationwide, not including Alaska and Hawaii. Your filing fees will be about $205 and again, by rule you won't have to go through any freq. coordination. The positive point of all of this is that your Club members won't need to get an individual license and they will be able to operate under the Club's Radio Station Authorization, but depending on the brand of the radio(s) they own, they may have to buy a real radio because they won't be able to program any Part 90 freqs in their POS CCR junk. In my Area, Phoenix, most of the commercial operations, at least the small operations, have migrated to FRS, or SMRs, or Cell Phones, and the VHF Part 90.35 freqs are no longer crowded. I very seldom hear anyone on a VHF itinerant freq. If you elect to go the Part 90.35 itinerant freq route, I would take a very hard look at the VHF Band since most if not all of your Club members may have to procure a real radio anyways. A lot less restrictions by going a Part 90.35 route. You just need to pick a band to use. One of the downsides to use a Part 90.35 freq. would be if you want to put a simplex base station or a repeater on the air. In that case you will need to go through frequency coordination and in the VHF and finding a couple of available freqs to marry up as a repeater pair in most Metropolitan and if not all rural areas, may be problematic. Finding a freq. pair in the UHF band may be a bit easier since the UHF band freqs are allocated in pairs whereas the VHF Band is not allocated in pairs and almost all of the VHF freqs are not dedicated/classed for just mobile or base operations, and can be used for either operation, except for just a few, and I mean, just a very small number of VHF freqs. are limited to a specific operation. At least you may have choices.
