One bug that I cannot duplicate is when just listening to the broadcast band (radio) and switching from FM to AM band, the knob would not tune the frequency. Second bug: Radio Setup: APRS mode enabled (A12 blinking) WX Alerts turned ON Dual Recieve with A-Band scanning VFO (6) and the display set to show the frequencies. As I was watching the 220MHz scan, the radio automatically switched to the MR weather memory (1). There was no audio, but the WX station was received full strength. From this state, I pressed the UP ^ scan button and the audio came on. It was then possible to use the dial to scroll through the 10 weather memories, but that is all. I tried to change the volume, but the volume showed 10 and would not change. Pressing A-Band or B-Band, or the MENU buttons had no effect. I was effectively locked in this state. I also noticed that the display would flicker on irregular intervals, sometimes the WX freq would flicker, sometimes both frequencies would flicker. I do not think I was receiving an actual weather alert, so I'm not sure why the radio switched to the WX stations. I powered off the unit off and was able to get into the menu to disable the WX alerts. I tried the same setup again and the behavior was repeated. I also found out that I can get out of this situation by pressing F/W 9 to exit the WX stations. When not scanning, the radio does not switch to the WX stations, just when the scan is enabled.
