Hi, I've just re-acquired a KX3, and have been trying it on JT65. As per recommendations I have been trying to use Data A mode, but trying to adjust the drive level is a nightmare, and getting the required 4-5 bars of ALC has been near impossible. If I switch to USB mode, I can set the drive

[Elecraft] K3 - Strange Tune Behaviour

Hi All, I've been having issues since last night with an inability to use the Tune Function on the K3. I use Tune to get a carrier to tune my amp (an Emtron DX-1). Usually this works fine, but now the Tune simply turns itself straight off after it is pressed when I have the amp turned on. The
