My point was default out of the box it doesn't need set. Its already set to a level.

Or not worry about it. I have the 275. Ive never needed to nor worried about squelch. I installed it, turned it on and talk to other jeeps. Simple.

The radio is not certified for other than ham. MURS and GMRS are not Ham.

Its a ham radio. If you want GMRS buy a GMRS radio.

How about just buy a GMRS radio then buy a HAM radio for other stuff.

Still debating on what to do with the 2 mics but got my heads mounted in my 2024 Nissan Frontier. Just enough room for dual E5 heads.

Dont have this issue with factory provided antenna's

Why would it matter if there was a list posted ? Majority of the topics on this forum are about uncertified radios over and over and how to modify, program or use said radios. @OffRoaderX is spot on. If it says GMRS its probably certified....not always but mostly.

As I've said multiple times I've had GMRS since I was a kid. Dad had a license and we rented a "PL" on a repeater originally. Later on he found a good used repeater and we had it on a telephone pole in town. Years later we ended up at a small tower on a hill. It was always used for "dad" on the way home and "Mom" saying she needs bread or milk from the store. No one else was on the channel. Once in a great while we would travel caravan style and use radio to radio. In those days portable radios were expensive and didn't work well. I dont think we ever had a portable until I got into it in the mid 90's. Even then it was a midland 2 channel xstal radio. During this time we never even thought about talking around the state let alone the country. It was used for utility purposes. We still use GMRS in that way for family use. I also use it now for off roading with JeepJamborree but that's all simplex. No need to talk 200 miles away. I still firmly believe the linking is pushed by unhappy hams. Same with nets and all that. While many think I hate hams I've been one for over 30 years. I use HAM radio for APRS, SAR and other uses. Again each service or technology is used for a need. No different than Cell Phone Apps. we use Zello to Patch SAR channels for situational awareness, Internet for console sites and plain old simplex to talk to teams in the woods. I hope the FCC clarifies further myself and will slow or put an end to linking for those that want repeaters for local use. Also I run 8 repeaters. None are linked, nor can be used in the same area. No need.

So someone else asked a similar but more specific question to the FCC and the responce was much different....Itsn ot my post but can be seen here - http://forums.radioreference.com/threads/considerations-about-linking-gmrs-repeaters.462408/post-3973769

I'd shortne the cable to bare minimum.

REACT was big back in the CB days. Many of the teams fell apart in the early 2000's. Our team used GMRS for a few years before they disbanded. Back then a team could license the frequency as well. This is actually how our SAR team got the channel and location we used for a few years also.

Use your cellphone and download zello. have family download zello. talk on zello.

Thanks @Sshannon I missed that in the firt post. So I guess my original statement stands. An antenna 10' off the gorund with a 5 watt UHF repeater into 50' of LMRish cable and an antenna isn't going to cover too far. I think many have this misconception that they can buy stuff throw it up and talk 50 miles casue other talk about that on the forum. Throwing an Midland/RT97 on a silo thats 150' in the air and field all around will cover better than the earlier one. I posted once previously about my Motorhome experiences. With 15' of cable and a good Laird antenna I got difference coverage depending on where I parked.

The top brass nut is what I meant. If its not recessed on the bottom to accept the plastic ring I'm not sure what the spacer is for. A normal 3/8" mount is pictured below and you can see the recess in the brass nut. A standard NMO wouldl ook like this

I dont see where you specified cable for the antenna eiither. For the RT shortest antenna cable the better. Better antenna and height. How heigh is the antenna now ? It needs to be up in the air.

Is the top nut flat on the bottom ? you didn't show that. You need the teeth on the bottom of the mount up against the steel bracket as well as the top nut.

Ah more ham crap on the air....ok then...

As said forget the repeater. Just use simplex. IF you are going to use it when you get someplace else using the travel tone would be prudent.

Why do you need a controller ? The MTR is a good unit and has built in functions.

It was alwasy common to test in the middle when we used CB and think GMRS would be the same. With that said repeaters are 467.xxx and simplex is 462. If you use simplex 99% of the time I'd test on a middle 462.xxx channel. For instance a 1/4 wave should work fine across the board. It realyl depends on useage. For my SAR stuff we always use the National SAR channel for tunign as thats the most important channel we use. Other channels are repeaters and a portable works fine so worring about a great single from the mobile is less concerning. Granted we are all in the VHF side and most folks run a quarter wave to eliminate then eed to tune to a certain frequency.

Not sure what kind of radio you showed Steve, but here are repeater settings for my stuff - GR1225 Calls it Hang Time MTR2000 Calls it Drop out Delay Icom Calls it Hang Time I dont have my Quantar or GTR8000 software on my home PC so can't show those.

You should also look at some radio propagation programs. I live in rural area. I have a DB408 on my house 40' in the air which is on a hill. 14 miles away I cannot talk to the repeater with a mobile at all. I loose the house about 6-8 miles away. My area isn't perfectly flat its rolling hills. My APRS barely makes it 14 miles on VHF with a gain antenna to a mobile 5/8 wave antenna. Yes some guys talk about 50-100 miles on a repeater but most are in a high location with nothing in between you and the repeater (LOS). If you can stand on your house and see the other house you will be good but I think 20 miles is stretching's it on GMRS for simplex operations. YMMV.

Normally in multiple repeaters you use a combiner on TX and a multicoupler on RX. The issue is the GMRS repeaters are pretty close and it takes a good combiner to make it work right. I have our SAR repeater (453.xxx) and a GMRS repeater in my combiner with 3 repeaters using a receive multicoupler. The 3rd SAR repeater uses its own TX antenna.

That also depends on if the repeater has the internal duplxer or internal. Mine is internal and the TX RX Port is the TX RX Port. The manual shows the modification. https://www.manualslib.com/manual/867444/Icom-Ic-Fr3000-Series.html?page=24#manual
