Looking for details from anyone who resolved issues with excessive transformer hum during transmit on a KPA-500.
I have a hum mitigation application note sent from Elecraft tech support. But the procedure recommended is pretty involved - removing front/side panels, un-plugging connections, removing the transformer, changing positions of the rubber discs, and putting it back together. Possibly more than once, depending on the results. There is a risk of breaking something, and I'm not sure its going to solve the problem if I'm successful. This is a new out of the box KPA500 kit. If anybody has any lessons learned I would appreciate hearing them.
