Overall, this is the best handheld transceiver I've used. Features and functions are great - this radio has plenty of flexibility. My only issue has been the steep learning curve for the programming software. It would be nice to have a well written manual on setting up channels, zones, etc. It took me several hours to figure out how to add some analog channels and set them up so that I could select them (assigning the channels to zones. Most of the time it took me is related to not having used a DMR radio before. Thanks to BYRG for having set up the initial code plugs - that saved me a huge amount of time and got me on the air within a day.
