[Elecraft] Low SSB out on upper bands

[Tom Bosscher]

    Up until today, I have only used my K2 on 75 SSB and 40 and 20 cw. 
Today I actually tried some 20 meter ssb, and I have very low output. On 
all the bands, with my K2-100 setup, where I leave the power pot, I get 
70 watts (CW) out agreeing with the K2 display within 10%. On 75 and 40, 
I can get 75 watts PEP out (I'm using a Autek WM1 peak reading 
wattmeter). But on 20 and above I get only 5 watts PEP or so. Yet the CW 
power is there. Is there something simple I am overlooking?
