Check the germanium diode that provides the voltage for the "forward" or, in this case, the power output, indication. There are 2-diodes, 1 for forward and 1 for reverse (SWR position). It sounds lik

With a slight reduction in readings. Using a Schottky diode would be a better approach. I would replace both diodes in the SWR bridge with like diodes just to keep some semblance of accuracy. Glen, K

I picked up what was left of an FL 2500 amplifier, which would be good for parts if someone is homebrewing an amp, or, if you're feeling ambitious, could be restored. It was part of a package deal wi

I would not be too concerned about leakage. It happens, but very very seldom. I have tubes that are still new in box from way back in WW2 that I have used and none have ever shown air leakage. Easies

Use the 10M band setting for 12, 15M for 17, and 20M for 30. Then, starting out with low drive power (about 10 watts) tune the amp like you would normally. The sweet spots on the Tune and Load cap kn

Yep. Transmitter power. So antenna gain can be whatever you can get. Same on our other bands. We can run legal limit with an amp, but we can get more gain by using a beam. There is a difference betwe

A 30 meter beam size would be between a 40 meter and 20 meter size and a lot of hams build both. A 3 element beam for 30 meters would probably give at least a 6 db gain, which is equivalent to increa
