Still no solution for my power problem. Some correspondence with Gary at Elecraft has me back where I started. I removed R6 and saw 0V at the output of U4 but 2.5V on the input of U4 coming from U1 (pin 3 on U4). According to the testing in the manual this should be 3-4 volts with a requested power of 5 watts. I replaced R6 and now saw the 2.5V on the output of U4. This is still low obviously. I reflow'd all the solder joints in the SWR bridge as it suggests and this has not helped. I'm not sure where to look next.
