Don, Thanks for the advice. That's a strong possibility, since I just performed the same successful repair on my KPA100, which may have been inline at the same time.
On this topic: A friend suggested putting a 1 megohm resistor across the antenna terminals to help dissipate static charges when used with an antenna that is "open" from a DC perspective, such as a dipole. Is this good advice? > Jonathan, > > If it was working before, it may be that the wattmeter bridge diodes in > the KAT100 were zapped with a lightning surge. > > I suggest the first step is to obtain 2 1N5711 diodes and replace D1 and > D2.
