I think FRS is the only thing legally available without a license. You can buy GMRS radios on Amazon that will communicate with FRS radios on all of the FRS channels, see here:

However, these radios are VERY limited in an urban area with lots of concrete towers. In my experience the GMRS radios on “high power” really only go one little valley over out in the woods. In the city you might get two or three blocks because of all the concrete. You are required to have a license to use GMRS and identify your station every 15 minutes but almost nobody does it. Hell, I listen to the local walmart using GMRS and you’re not even supposed to use it for commercial purposes.

Maybe Meshtastic? That’s a radio I haven’t messed with and I don’t know about it’s performance in an urban environment.

Ear piece highly recommended. The audio is not like a phone call and in a loud environment you will not be able to copy. Practice beforehand because radio is not like a phone call, you need to have some experience.

Those who cannot play the sport any more may coach

not plural beans anyway. we like to be monogamous in my house.

just please one bean, thank you.

but if you can find one that wants other beans, more power to you.

cruising, eh?

Basically, if you don’t have a phone the cops can easily backdoor, you must be a criminal.

“What do you have to hide?” taken to it’s logical conclusion.
