I suggest a CB radio while on the road and a satellite phone for off the beaten path. Why? I agree with "retiredtoo", you can avoid the filth and get very useful information from CB while on the road. CB takes no license and is cheap to own and operate.
The satellite phone is invaluable virtually anywhere. Yes, it's cost is high as is the yearly subscription but what price safety? I think it's very very worth the cost and utility. And they can easily be rented for trips if you don't want to buy one.
Ham radio is not the choice I'd make for getting information while on the road OR while in the backcountry. 2M won't get you out of a canyon and you sure don't want to have to string up a longwire antenna to get on HF.....during an emergency.
Before you start bashing me, note this: My parents were both ham radio operators from the 50's. I've been a ham for many years. I've used satellite phones, CB radio, and ham radio.
That's my suggestion.
