This is an incorrect impression. There is a utility put out by Uniden (actually UPMan) which will allow you do this (it is not complete right now but it is a start). You can get it from the Yahoo BCD396T group in the files section. It was (the utility) originally built for the BC246T but outputs the same basic file format. You can load it into the UASD software and any fields needed (that are not there yet) will be added by the software for upload into your radio.
