Ed, No, R6 will not influence the bridge null. You are instructed to leave it out until you check the voltage at U4 pin 1, during receive - it should be zero - but you can also check that with R6 in. The zero voltage in receive is the important one to the rest of the K2. If you do detect voltage during receive, then remove R6 until you can find the problem, otherwise leave it in. The check for voltage in transmit is to be sure things are working right in the wattmeter output, but that can also be checked with R6 installed.
