I found the problem.? I was curious about the output power and turned on the power display.? When the display didn't show power or swr, I started troubleshooting that symptom.? It didn't take me long to to track the problem down to a bad solder joint on T507.? Repairing that connection corrected the LPF sweep issue and the swr display.? It makes sense, the measuring circuit was common to all of the LPF paths, thus the across the board impact on the sweeps.

Thanks.
