[Elecraft] K2 KAT2 pad B problem

[Jay Sissom]

Hello, I'm having a problem with my KAT2.  I have built the board and
I'm on page 17 of the manual where you measure the voltage at pin B.
I always get 0 volts here.  Here are some other observations:

I have the ATU menu set to CALn, Power set to 5.0, frequency set to 7.100Mhz.

After pressing tune:
  pin B = 0V
  U4 pin 5 = 3.8V
  U4 pin 4 = 0V
  C55 setting 009

With an external wattmeter between the dummy load and Ant 1, it reads 6.5W.

Any ideas where to look for the problem?

Thanks & 73
