[Elecraft] K2 - 40m transmit problems

[Zac Brown]

I'm getting HiCurr messages when I transmit on 40m, the bargraph shows 
multiple bars lit, and I can hear a very faint squealing sound coming 
from the K2 when I transmit.  I've built the RF probe and I'm going 
through the signal tracing steps in the manual.

On the PLL Reference Oscillator steps (appendix E, page 10) I am 
measuring U4 pin 1 at 0.252 V.  The signal tracing instructions say that 
it should be 0.8-1.8 vrms.  I then started looking at Q19 and am 
measuring G=1.0, S=-1.0, D=8.0 with my DMM.  According to the DC voltage 
tables, I should be seeing G=0, S=0.8, D=8.0.

Any advice on where I should look next?

Thanks,

Zac
