I have the "new" BC346XTC scanner, but I want to programming it using my computer. The problem is, I can't find any compatible software. I have tried FreeSCAN and bcTool, but they do not work. The BC346XTC is pretty much the same as the BC346XT, but just has different battery requirements (BC346XTC < UnidenMan4 < TWiki). It would be very useful, especially for trunking systems, if I could program the scanner from my computer. I have the USB to Serial adapter and it works perfectly with my computer.
