Quite a few of the old REACT groups used to run GMRS travelers assistance repeaters. "Back in the day", 462/467.675 with a 141.3Hz PL was known as the "Travelers Assistance" channel. Many had open repeaters on that frequency/tone pair.
Key there is "used to", ""Back in the day"", and "was". The oils of Yesterday do not butter the Parsnips of Tomorrow, dear Sir! 😉
However, that frequency pair/tone set is -NOT- restricted to emergency or travelers assistance use. Some repeater owners could require that for their own system, but it is not a restriction that exists in the GMRS rules.
No, and it shouldn't be a restricted channel, just one with an emergency caveat. Just require that a repeater on that
designated pair be open for any emergency traffic on the
designated pair/channel. That's not an onerous demand, just one that would prioritize the community over the repeater owner. Don't want to be interrupted by emergency traffic? Great! There are other pairs available.
So, really no reason to try to use MURS, or modify the MURS rules, when this already exists in a lot of places.
First point, one that I did leave out of this quote, is about mygmrs.com. That site is a joke; it may as well be on GeoCities for all its lack of usefulness to anyone traveling. It's little more than you and I BSing over beers by the fire at deer camp.
I agree that MURS
as it is would be a waste of time and effort. I think there's a decent case for a rule modification, just to bring it into coherence with FRS/GMRS. 5-7 high-power pairs with appropriate interstitial channels would make a very useful service, especially West of the Mississippi.
I see absolutely no reason not to carve out a chunk of VHF for this, other that the PS sector wanting to keep control over a section of spectrum they claim is better served by 7/800 MHz. Sounds like a great idea to me. Get ALL Public Service comms out of VHF and UHF; you can have all of 7/8/and 900. 700 MHz only for Public Safety? Great! Get your carcasses up there. Put the spectrum that's useful to average folks back in their hands. Not enough room on 2 meters for your club's repeater? Pffffft. There's plenty of room from 148 to 156 once PS moves to 7/8/9. Same with UHF.
Sarcasm aside, there's absolutely no good reason that we can't have Citizen/Public Use segments in ALL useful bands AND have proper coordination for PS, business, and citizen use, other than inertia and crybaby-itis.
