[Elecraft] K3 strange behavior

[Andreas Wachter]

I’ve noticed some strange behavior on my K3: sometimes on CW in the middle of a transmission, the K3 doesn’t switch back to RX mode and the red TX LED stays on - lost a few contacts during today's NA CW QSO party as I had to reset the K3 in the middle of QSOs. Only way to get the receiver going again is to do a power cycle (there may be other ways as well, I don’t know). Also I have had all characters of the LCD display come on and back off again when turning VFO A knob. So if I tune slowly in one direction, the display switches from normal to all characters on and back to normal and so on. So something is definitely wrong here. How do I solve this problem? The K3 does not operate reliably anymore.

Thanks,
