I just had something weird happen.? I was on 10 meters just listening.? I had the Xiegu Speaker plugged in.? I left and returned and the radio was producing this tone.? I could tune up and down.? I could switch bands.? It still produced this tone.? I turned it off.? And it was still producing this tone.? I unplugged everything.? The green light was still on and still producing a tone.? I turned it back on and it was still producing the tone.? I cycled it on and off a few more times and it was still producing a tone.? I did a factory reset via the menu.? It was still producing a this tone.? I decided to take a video of this and even did a factory reset.? And it was still producing a tone.? While off I could plug the Xiegu speaker in and it this tone would switch back and forth from the speaker to the x6100 while OFF and unplugged.? The green light remained on still too.? I got to turn this thing off.? Did some searching and could not find anything.? So in I go.? First time opening it up.? I was aware of the ball bearings after watching the tear down videos.? I knew where to go.? Manufacturers really should try producing their own teardown videos like that instead of random people, anyway I digress.? So I pull the sides take the two screws holding the back battery plate off and there is the battery.? I pull the connector out half way and sound stops.? The connector doesn't come out all the way because of the battery.? I slide it back in and no sound.? Put it back together and power it back on.? No sound.? Connect my antenna tune back to 10m and everything appears to be fine.? My concern is I now have to carry a screwdriver to open up my radio.? Will this happen again?? What could have caused it?? Anyone know?? When I was in the menu while the tone was going off, i went in to the system info and under the Base version it did not have "V1.1.6", it just had a question mark "?" here.? When I go into this menu after doing the hard reset like I did, then it shows up correctly.? Has anyone ever encountered this issue?
