I picked up a used BAOFENG UV-B5 and used CHIRP to download all the channels in its memory… What I found in it was an odd mix of FRS, GMRS some very odd simplex channels etc… I erased all those and uploaded all my local HAM repeaters just like my other handheld. Everything seemed to go well with CHIRP and I confirmed the memory update. However, when I unhooked everything and tried to use the radio its like there are no memories in the radio at all. It just act like VFO mode. How do I get this radio to channel memory mode?
