It is interesting how a simple fix for these problems doesn't seem to be well known. I submitted the article draft to QST, and it was questioned by the Technical Review folks, and although I have bee

I would say Art Collins did not agree with your assessment when he designed the 30S1. The problem of mismatch is often the result of the use of two or more finals in the amplifier and their resulting

Yes indeed. In fact, there were two different lengths in the Collins 30S1 manual, one for their transceiver and one for their transmitter. "In cases involving RF signals, some time will pass during t

You will often find the input SWR higher on one or more bands. This is especially true with amplifiers with torroidal input. But as I have said before, one test is worth a thousand expert opinions. W

Since you have already run some jumper experiments with no success, why not measure the 25 ohm shunting resister and see if it has changed value somewhat? You could start by just examining it visuall
