Shows how much I know. My question should have been for recommendations for devices to communicate between RVs while on the road. Sounds like CBs are passe. What are people using now that doesn't require a license? What's an FRS (bubble pack)? I have the little hand held radios and they don't seem to do well over distance.
CB's become an issue when the atmospheric conditions allow signals to "skip" and roll in from all over.
Not sure about you, but with a wife and son in the car, I don't want/need them hearing some of the language that gets used.
FRS was changed last year. It now allows more power (2 watts) and additional channels.
Pick up a bunch of FRS/GMRS radios (often called "bubble pack" because of the packaging) at WalMart, etc.
They are UHF, so pretty much line of sight.
Get some rechargeable batteries and you'll be good to go.
The big benefit is that a lot of people have them. Not so much with CB's. They'd be a lot cheaper, too. A "decent" CB is going to cost north of $50, plus you need a good antenna, installation, etc.
FRS radios, throw some batteries in them and you are good to go.
Don't fall for the cheap Chinese radios that you'll find on e-Bay and Amazon. They require programming and are not legal for use on FRS.
