You didn't mention your programming of the repeater or what it was in regards to bandwidth. Using a repeater with midland radios you will want to set the repeater for narrow band (12.5) for best performance. Its still not ideal but will work much better than wide band.
-
I think it is different depending on who owns the repeater. I have alot of funds into my systems. I did it so myself and others could use the service. I don't want unlicensed CCR junk on my repeaters for multiple reasons that I wont discuss here. I specifically have my repeaters programmed to help eliminate that. It still happens from time to time. I have never not given permission to a licensed GMRS user to use my gear. Have a valid license don't be an idiot and use it.

I bit the bullet and installed the MXT275 in both my JK and JT over the weekend. I still have my APX radios for public safety. I did this for the reason of more and more folks are throwing them in vehicles and it was getting to be a hassle to figure out which frequency/pl tone i needed in my commercial gear each time. Being a lot of folks are not on the this forum or any they still buy the radios from midland and use them out of the box. This has been beaten to death and Im sure will continue for years. But its the best option for my use. I think those that are truly into GMRS will still use commercial gear, however those that use the radio as a hobby for another use will just buy the midlands.

DB404 and 408 is a good one in the commercial world. They normally hold up very well. I run the 404 and 408 on my GMRS repeater sites.

Depends on your local coordination group.

Nice clean install. Sure it will do fine.

You don't mention the antenna cable you use at home on your 40' antenna. If that isn't LMR400 or larger you probably don't have much power at the antenna. As others said the radio your using to test is also not the best option for your plans.

Id try to keep the antennas 16 inches apart. On my Motorhome I removed my AM/FM and installed a NMO mount there with a Larsen mutliband antenna. I then use a diplexer to pull UHF and VHF to each unit. For my scanner I just used a glass mount. 99% of the time i am listenign to the local P25 trunking system anyway. On my ladder is my Larsen fiberglass stick for my GMRS repeater. Its about a foot high so still lower than my SAT dish.

Thanks for the reviews. I guess next week I need to order one for my Motor home. This will be an ideal setup vs the GR1225 for dry camping. I can see other uses as well. I already have a small fiberglass stick i use on the motor home.

We are getting off topic here.
GMRS does not have to ID. Period. Per rules. None of mine ID. Commercial Part 90 Repeaters must ID per rules. Alot of Part 90 repeaters ID with no PL/DPL tone so if you have a scanner with PL/DPL enabled you will never hear the ID.
-
Keeping in mind, older part 90 radios are all wide band, while newer ones are narrow band. Though, some newer radios have the option to turn on narrow banding with appropriate software and/or permissions.
Correct. Unless your using pretty old programmable gear most stuff on the market supports both NM and WB. My radios are all programmed with both for this reason. Just know what is in your area and what you want to talk to. Knowing the gear you are buying is a plus. Most of the decent used gear that programs with windows does NB. There is still alot of old gear (GE MVS<MLS< Motorola GM/Maxtrac) stuff thats out there but normally a PITA to program so folks dont grab it like they used to.

All in all this is a good idea. Could they save money by going used part 90 gear. Most likely, however this is exactly why Midland is selling like it is. Its easy and simple and you can go anyplace to get a radio ready to roll. When my father bought his first one i cringed. After learning the issues and how i could help fix it it does the intended purpose. If someone wants to add a second or third they jump online and order another. I have one repeater specifically in NB just for some friend that have the midland gear. I am actually in the process of switching my repeater in my motor home to NB as well being I take it on some Jeep rides and more folks are going to GMRS in the off road world.
I still use my part 90 gear (APX and XTL) for most of my communications but having something that works for these folks and others is a good solution.

As stated here it can be what ever way you want it. It really boils down to what subscriber, radio you are going to use on it. If your plan is part 90 radios go wide. If they plan to by midland radios use NB. I have a mix of both due to the users on each.

Also connectors ? N ? Adapters ? What cables are on the duplexer inputs from the repeater ?
-
I may of missed this but what area in VA are you talking. I have multiple GMRS repeaters sitting looking for locations. You can PM me for details if your interested.
-
Rich, Any update on your end ? Have you had time to test one of these ?
-
I think the only reason the 1/4 wave is better is it is more wide band than most gain antenna's. I actually run 1/4 on my work vehicle for this reason. I can go from Ham to T Band without much difference. I wouldn't say its the best solution but worth a try to see.

Also check for splitters in the house. Way back when i worked for Spectrum we would get calls with similar complaints. Alot of times we found splitters with 2 cables and 1 or empty ports with no terminations on them. As others said check the COAX. Anything less than RG6 shielded can cause the issue. My motor home would block on on multiple channels when my GMRS repeater (in the MH) would transmit. Found alot of connections (rg58) with crimps looking like they used a pair of pliers. I replaced all cable in the MH with RG6 quadshield and all my issues went away.

Non Standard Repeater Offsets
in FCC Rules Discussion

I guess i have been in the LMR world way too long but i dont think i have ever seen a UHF repeater that did not use 5mhz. That is the standard in LMR and most licenses will show that. I agree its not spelled out in GMRS rules but I can't imagine anyone who would use different output and input frequencies as you described. Even in the Ham world most all UHF repeaters are 5mhz apart. I dont see a need for commercial providers to make a radio to be able to use anything other than 5mhz. JMHO
