you'd be about 40 watts over the legal output limit if that figure of 45 watts is correct. GMRS and FRS radios are limited to 5 watts of output power if I'm not mistaken.
Has anyone used the GMRS Icom F221 / F121 Radio? It is a 45 watt unit which I will pair with a 5db gain antenna.
I am thinking if getting this in my FJ60.
While ham may be the test option for general communications, GMRS has its place. As for Emcomms on GMRS, there are a many groups using GMRS for emergency communications, While not as pracical as it was in the past SAR groups, I heard of one skywarn group, Several REACT groups and neighborhood watches. Keep kin mind also that GMRS was once available to business, I know of a couple police and fire agrencies that are still licensed on GMRS. You can license business anymore but a few grandfathered places exisitcorrected.
I'd go Ham too but being as how I'm already a Ham operator I'm probably a bit biased.
It really comes down to this, who are you going to talk to and where are they gonna be when you need to talk to them? If you're looking for something to communicate directly with another person(s) with and they've got a GMRS radio, you're golden. If on the other hand, you're out somewhere trying to raise someone in an emergency, you're at the mercy of the equipment you chose.
I don't know of any emergency communications organisations that use GMRS, on the other hand, there are an awful lot of them using Ham frequencies.
I checked the spec sheet and I don't see where it says it's a GMRS unit unless that's within the UHF/VHF frequencies?
Also I agree that unless the folks you plan on communicating with regularly have a radio which supports UHF/VHF, I'd stick to either GMRS/FRS or CB as those are the most common off road communication standards from the folks I've run into.
