[Elecraft] K2 low output on 80

[Phil Zminda]

I recently noticed while on 80 cw with a watt meter attached, that my output on 80 cw  was only about 2 to 3 watts at the low end of the band, even though the drive setting was for about 12 watts. I can't say I that I have checked the output on 80 cw recently, so this may not be new. I built and aligned the K2 about a year ago and have the built-in tuner installed. I re-checked it with a dummy load and got the same results. If I tune to the center of the band the output goes up. At the high end, it also appears to drop off. Other bands seem OK. I intend to open it up and peak the alignment, but before I do that, is there anything else I should be looking for? 

Thanks,
