There is no tuning on the LP450NMO antenna. Slap it on and enjoy. I ran mine under the softop for a few years until i wanted a better antenna and went with a 1/4 wave on a mount outside.

Been doing Fire/EMS and Search and Rescue for over 25 years. To be honest I enjoy fire/ems, but I really like Search and Rescue (Wildland). I use radios much more with SAR as well as ICS and other tasks. Been involved in some large scale incidents and at one point was looking to be more involved but work moved me to VA and the area I am in SAR is a joke. Its sad as alot of training in NY came from VA and they were in high regard. Anyway I'm still a life member in NY and go up quarterly for SAR training. Dont have picks right now of my JT, but run the APX 8500, FTM400 and have both a 275 and CMX760 I can swap in when needed. Been meaning to get some lights on it but time has not permitted. Our JK does have dash lights, APX8500 and Kenwood 700 with both the 275 and CMX also. Work truck has multiple APX8500's, 7500's and a CMX and has lighting. PS - Like your setup in the JT on lights. I need to find a decent package for mine.

Spend the money on a good NMO mount. The Larsen HF mount is ideal for a fender bracket. Just slide a piece of heat shrink over the cable to the mount. I have run them on multiple vehicles and they will outlast any basic cheap mount. https://theantennafarm.com/shop-by-categories/shop-all/mobile-antenna-mounts/nmo-mobile-antenna-mounts/266-permanent-hole-mounts/289-nmo-3-4-hole-mount-no-connector/larsen-nmokhfcx-detail

I run the 272 in both my JK and JT. I like the size and simplicity. Just pick a channel and go. Great for wife also. If I need other than GMRS I can use my APX.

GMRS and HAM are two different things. Many folks do not get on GMRS to talk. Your better off on amatuer radio if thats what your looking for.

Most NYC repeaters dont respond. There are no "groups" per say in NYC. GMRS is not like a HAM club.

Go to the search window on the forums - This is for the forums only and not the MYGMRS website.

Top of mygmrs page - got to mygmrs.com click sign in on right then go to repeaters and it should show yout the info. It is not the same login as the forum.

Depends on the radio. All my motorola gear allows alias. I can add an alias as a call sign but mostly its just a unit number or vehicle ID. We use a list thats standard and each ID represents something. ie: last digit 9 refers to a base radio...

Sorry I use it on all my radios so I know which radio is being used. Each radio has its unique ID. With many users on a repeater its nice to keep track of who just called. JMHO

We spent 6 months arguing over this before. Don't think we need yet another thread. Both points of view were discussed. Use a channel you want and go from there.

If you are using repeaters change it to wide. If your not dont worry as 90% of the other folks will most likely be narrow.

I get your opinion. I'm not debating that. What I asking is where in the rules is this stated.

The only problem with listing them is really getting a repeater on the air. There are tons of repeaters on the list that have never went on the air. I'm all for adding if your seriously adding one, but if you dont have equipment or plans I'd wait. Too many people look at the repeater map and program a radio to use a repeater that's not there. With that said there are guys who spend alot on getting a repeater online and they do follow thru with the work. Dont want folks to think everyone lists and doesn't do the work.

So where in the rules does it say that ? Many folks use MDC as well as P25 and other signaling on amateur radio. Many folks use MDC on GMRS.

And who do you think would do this ? Cell companies dont care about critical infastructure at all. Its all the bottom line. I have seen some rough cell sites over the years. Many with no generators, small battery plants and horrible installs. Some good but the point is who is going to spend the money ? I get there is no "real" service to get help in an emergency but GMRS isn't it either.

Yes to both.

I run 3 APX 8500 all bands, 2 to multi antennas and one on the vhf Normally

So Im a bit confused how are you linking. If your going to be a "mobile" on the 550 repeater that means you are TX at your site on the link radio on 467.550. What is your repeater ? I would assume no matter what you do you will decense the repeater at your site major when the 467.550 radio is keyed. I dont know of a filter that will keep that close of a spacing out of the other. RF linking in GMRS is about not able to be done in my process. I can't see where you could get the seperation.

you should be good with the first option. I run similar on my F150 (6 NMO mounts). Rear is CB and VHF, front are all bands, and farthest front are UHF

Depends on expectations. There are no GMRS repeaters in your area that work well so I would look for good part 90 gear.

Where ? https://mygmrs.com/repeaters List all sorts of repeaters and has multiple filters by location.

Hardline is LDF4-50A. Its a very stiff cable and is not great for bending. Thats the benefits of loss. If your under 50' grab some LMR400. Anything more that 10-15' of RG58 and you wont have any signal on the antenna port. Who tuned the antenna and set it up on frequency ? It sounds like you ordered a TRAM style put together antenna and they need cut to specific lengths to work properly. As said above this was ordered and programmed for GMRS ?

SO your going to need some basic test equipment to determine your issue. First is a DVM and second is a basic watt meter. First thing I'd do is take a DVM and check the antenna line and make sure the center and shield are not shorted. You did not mention cable type, length or antenna specification so can't help alot without that info. A watt meter would allow you to test output power of the repeater as well as antenna system. The RT97 is a great little repeater for home use and with the proper accessories can be a great little box. Who did programming and tuning on duplexer ? Did you specify the repeater frequency to them when ordering ?
