I believe they are all BaoFeng UV-5R+/UV5R.
They were recommended for us when off roading to communicate between vehicles, but never seemed to work great at that.
Somewhere I think I still have the usb programming cable for them.
Edit: apparently the intent of my post was lost in my poor wording of the title. It has been updated to better reflect that I would like to use them, but for what? And how?
Well yes, but can they be used as police scanners? Weather update radios? Or are they strictly to communicate with another hand held?
They have a recieve range of 134-176 I think and 420-480, as long as it's standard analog you should be able program in some fun things to listen to.
I have one setup for railroad frequencies and I hear some unique conversations.
My radio dummy tip (I’d definitely not an expert) is definitely go outside when scanning for interesting stuff to listen to. It took me a few afternoons of scanning to find anything, let alone anything interesting. Hopefully you’ll have better luck :-)
