John, our club's K2/100 does the same thing - high current on topband, but
it seems normal on all other bands. I mentioned it on here some months
back, and received some useful suggestions to try, but I never did find
anything wrong as such, or a cure for that matter.

Subject: [Elecraft] K2 #4970 is now a K2/100

Hi everyone,
Last night, I finished building and testing the KPA100. Today, I made
several QRO contacts and got good reports on the audio from the KSB2 and
the Heil desk mike.
K2 # 4970 also has the noise blanker, DSP filter and 160 meters installed.
The DSP filter is incredible. Signals seem to just pop out of a nearly
quiet background when it's on. I love this radio. It's better than my 756
pro II.
The only odd things I encountered while testing the amp were:
1) on 160 M the current draw is about 27-28 amps at 100 W out, all other
bands are 20 amps or less;
2) maximum attainable output on 30 meters is 68 watts; all other bands
reach 100 watts + except 10 meters, which reaches about 90 watts.
Other than this, the radio and all its options are working perfectly.
What I am wondering about is whether or not the amp is working normally.
Has anyone had the same experience
Thanks and 73,
John, W2GW
