C1 varied the power output, but the SWR was fixed at 9.9-1. The problem
was a short between the output of the two op-amps U5A and U5B that
amplify and buffer the forward and reflected voltages before they go to
the processo
Group - I am building a new K3 kit and ran into a problem today. I did
the initial power on test in the build cycle with no issue. I am now at
the initial configuration point after the radio is built but before the
100W amp installation.
When I powered up the radio, everything was fine, altho
