This will shed some light on the situation. Shows just how busy the frequency spectrum is:

Here is some good info in support of the KG-935G/plus and why you will not likely improve on it.

If you are thinking of getting a KG-1000G later it may make sense to go with KG-UV980P as they are the same basic radio. I have the KG-1000G Plus. It is a very nice radio.
Just looked it up on "Buy Two Way Radios" The H (ham) version has removable antenna's (comes with two) but the GMRS has a non removable antenna.
I personally do not like that.
Just thinking out loud here. Could it be that the proximity to the bigger antenna is amplifying the signal from the other antennas? They are made for the same frequencies. We are talking about electromagnetic radiation after all. An electromagnetic coupling in close proximity.
Would be interesting to know the range of the enhancement from the repeater. Did you test to see how far away you still get an improvement? Does it drop off gradually as you move away?
They certainly can, if you have a good understanding of their capabilities, and have a plan, and practice that plan with your family.
This is a good place to learn and ask questions.
What you may be missing is the purpose of GMRS. It is intended for family and groups to stay in touch. That's why your license covers your immediate family. It's not really about making random social contacts although some use it for that on repeaters. Could be there is just no one around that wants to talk to strangers. Ham radio is better if that is you goal.
Glad to help.
I do not have that radio or know anything about it so I will let others answer your questions about it. Just looked it up for reference:
https://www.ameradio.com/product/5165/description.html is this the one?
I assume it requires software to program do you have that? It could be a project to get it set up for GMRS.
Good luck!
The Midlands are very basic radios. They do not have removable antennas so can not be upgraded or connected to a car antenna. They also do not use repeaters. They are fine for basic simplex use like camping with the family, hunting etc. I have six of them.
WSAT598 that's a cool call sign! That Tiger Mt. repeater really has some reach.
One thing to keep in mind with the whip antennas is to keep them vertical while transmitting. I believe that Abbree is a copy of the Nagoya NA-771G https://www.buytwowayradios.com/nagoya-na-771g.html?___SID=U which is a very good antenna. Is it as good as the Nagoya? I don't know. And of course getting outside and up high will help.
Welcome!
You bit off quite alot for your first GMRS radio. Here is an article that is good for beginners to read:

Hello and welcome!
I am up in the San Juan Islands and I hear the Tiger Mt. repeater very well. Where are you located?
I don't have anything to add to your theory but it sound plausible. I had to look up QRM (man made interference from electronic devices)
as opposed to QRN (interference from natural source's) Very interesting stuff!
I don't know how many are using SDR's to monitor GMRS but we do have a few ham's around here that may have something to offer.
Thanks for sharing something new and interesting.
