Programming is pretty easy with Chirp. For the RH-5 and Chirp, you down load what is in the radio to give you the basics and settings in the radio.
Make changes, add channels, frequencies and name them, set any tones and then can upload to the radio.
With Chirp you can also change the front display message when the radio is booting up. Mine display my name so I know it is my radio if I loan it out.
You can find the programming cable on Amazon for the RH-5.
You can use this web site to see what frequencies are being used in your area that are registered. All of your local government frequencies will be listed. If a small business is running radios without a license, they would not be listed here.

I also would like to install a comm system in the Jeep, as it would make communications in the Jeep easier with the softtop on or no top at all.
I checked out the RT Systems site. I may pay for their software for my RM-50 to see if I reset it to factory and then reprogram it if it will fix a few of the issues I am having with it.
If you need help programming with Chirp, let me know.
Might be an article also on how to!
