That is a very interesting idea. I wouldn't have any idea how to build something like that, but it would be useful. If not that, at least I need to devise some kind of high SWR shutdown for the amplifier. I lost one FET already and it will surely happen again. I need to make a few small changes to the coil and variometer. It just has enough tuning range for dry conditions. When there is rain or ice I cannot tune far enough with it. I think I chose the wrong gear motor to turn it also. It works fine but the tuning rate is very slow. I should use a motor with more RPM. :-) 73, Paul
