Just a FYI after several hours of trouble shooting a receive and scanning issue you can only use the "same" code plug a certain number of times even though you have saved it under different name(s). Discovered this while trying to set up different "zones" or "groups" with 2-tone alert on 1 channel and the fire department's repeater / talk-around on another channel. I updated the firmware and used the current version of CE142 both legally downloaded from the Vertex Site, I have a user account with them. The same goes for the contact list if you edit one or two contacts ok other than that, do yourself a favor start a fresh code plug, might be a pain to reenter everything, but its worth avoiding the headaches trying to trouble shoot a existing CP. Also before you down load the new Code Plus down load a factory default code plug for your radio to make sure everything is set back to new, and you get the results you want.
