K3 strange behavior

[Elecraft mailing list]

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,

Andreas, K6AKW

Have you recently upgraded the Firmware, if so, try reloading previous version.
I had a similar problem which cleared up after going back to previous F-W,

Thanks for your reply. Yes, I did upgrade my K3 to the latest firmware. Not sure there were problems before since I bought the K3 used and the first thing I did was upgrading to the latest firmware. How can I downgrade the firmware? The Utility doesn’t seem to give me the option to select a particular firmware version.

Best,

Andreas K6AKW
