a friend of a friend bought 2 W7's off some guy who got them from some state auction. I read one them, edited the code plug that had 1 channel in it to a VHF channel we use around here and was able to tx. So I opened my code plug (w4) edited the whole damn thing (trying to save time from rewriting his from scratch)and couldn't write to the radio, I was getting a message about features don't match? I then powered the w7 head read it again and edited its own code plug to 73 channels to RX only except for a couple of his own channels, then tried to write it and now it won't write because it isn't narrowband compliant, it's asking me to update the firmware to the radio. Can this still be done with this radio? He has 2 of them?
