[Elecraft] fun k2 debugging

[Robert Greenwalt]

So I have a K2 all put together.  I thought it was receiving fine - I didn't
try transmitting as I shamefully don't have CW down yet.  I got the ssb kit
and put it together and it didn't transmit.  I stripped it out (jumpers back
in place at W2, W3 and C167 is back in) and tried testing cw transmit and
found a problem, but didn't fix it.  So now I'm testing the voltages and
finding some odd numbers.  Perhaps they've been seen before:

Q18 S is giving 4.9V instead of the suggested 2-3V
Q18 D is giving 8V instead of 6.3
U1 pin9 and 10 give 0V
U4 pin3 gives 2.4V instead of 0
U4 pin7 gives 5V instead of 0
U4 pin13 gives 0V instead of 4
U4 pin15 gives 2.5V instead of 5
U5 pin1 is 5 instead of 0
U5 pin2 is 0 instead of 5
U5 pin4 is 0 instead of 5

Suggestions on where to start?

Thanks
