Are all the other bands working ok? From what you describe in the mail below, it sounds to me like you might have a sticky K5 relay in the BPF stage. I'd suggest contacting Elecraft support over that one. 73, Matt VK2RQ

To: <elecraft@mailman.qth.net> Below is the message I posted at the end of July i have since discovered during a re calibration that I have exactly the same problem on 30 meters 10Megs. Looks like the M3 is slowly keeling over on me. Hi, hopefully someone can point me in the right direction to cure the problem that has manifested itself on my K3. When I TX using more than 11 Watts on 20metres shows HI CUR on the display. When I TX using more than 20 Watts on 20 Metres the display shows HI CUR for a second or two the the rig switches itself off. I have tried 2 different antennas and a DUMMY load and the results are always the same. I have tried both antenna connectors, I have also checked the power supply and it is feeding 13V into the rig. I do have the internal antenna tuner fitted, When I tune on 20 metres I do not get the SWR reading at the top of the display. All I get is -- at the top and 5.0 W at the bottom with reference to tuning. With the internal ATU bypassed I get exactly the same problem on 20 only HI CUR and switches off.
