Range depends entirely on the terrain. My friend and I have been lass than 1/2 mile apart but around the point of the mountain and can't talk to each other. Several times we call someone who is up higher and they will relay a message. Same radios in Colorado or over water have great range. The camp I hunt at has gone almost entirely to cell phones.
If there is foliage on the trees you get much reduced range... I use the old Motorola 250 and 280 models... No leaves on the trees I can get 6 miles reception... Leaves on the trees and 1-2 at most...I found the newer Motorola models are not as good as the old ones...
Our coyote hunting group switched over to marine band radios. Big difference in range
I guess this is pretty common? Just curious as I had been tempted to use marine band but the (slim?) chance of the 10K FCC fine was a deterrent. I was able to find a couple of cases where hunters were busted.
The lower FM frequencies used in the marine band do penetrate foliage better than the higher frequencies used by FRS\GMRS radios plus have the benefit of higher wattage. MURS is a legal lower FM frequency option, but I can't find any "weatherproof" options to purchase.
HAM is a lower FM option, but none of my hunting buddies have a HAM license.
We just use the Midland "extra talk GTX" on the higher power GMRS only channels, but on longer drives in rugged terrain the signal can be hit or miss. At least it works (slightly) better than the lower power FRS channels. I also put a mobile GMRS in my truck during hunting season and it reaches out a bit farther with the better antenna on the roof (or of you need a base station at camp).
FCC changed the rules a year or two ago and you now do not need to pay $ and get a license to use the GMRS channels on these and similar wally-world bubble pack radios (if you ever bothered to read the fine print on the last page of the instruction book LOL).
