I've got 2 of these radios, the oldest being over a year old. I've rarely (Twice?) had the lockup problem, but cycling power straightens it out. CHIRP works well with my setups. I've always had good reports with a variety of antennas. Currently both using the MFJ quad bander. Last winter, a sheet of ice broke my antenna, I didn't notice until I keyed up and filled the cab with smoke. The damage was 1 PIN diode in the band switching section. It was easily repaired. Internally, this seems well built. I've used the cross band repeat. The Chinglish manual makes it sound much more complicated than it is. If the buttons appear locked up, the first thing to check is the 'lock' function. It is enabled by pressing the lower left knob for a time. It is so easily locked and unlocked by accident that this feature seems less than totally useful.
