[Elecraft] K3 intermittent low power output

Dave, It's worth removing the front panel assembly, cleaning the connector pins, applying some 'Contralube' (obtainable from Maplins) to the pins and re-assembling. A year ago I had all sorts of problems with my K3, including that which you describe. The above measures completely fixed it.

Maybe John, it is serial 80 from November 2007. Does that problem also reduce the overall output as it is low power when using the LP PA as well. 73 Dave, G4AON How old is the K3? You don't have the KPA3 corroded pins problem, maybe? 73, John n1JM

[Elecraft] K3 intermittent low power output

My K3/100 has developed an intermittent transmit fault. The power drops to a very low, but not zero, level at any power setting using either the LP or HP PA. The symptoms/set up are as follows: Mode CW Using the KPA500 with it (not sure that is relevant) ATU not in circuit Power is low as
