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?
Makeshift Repeaters would be an obvious solution :)
