thanks for the tips. i figured the scope with a 10x probe would interfere with the antenna but assumed it would drop the voltage somewhat but still give ballpark measurements of resonance. i didn’t think it would actually be adjusting the resonant frequency of the antenna system. thats interesting.
when you talk about measuring feed voltage are you measuring ac or dc? do i just use my digital multimeter to do this or do i need some other gear? what about phase angle, what do i use to measure that?
i know that sstran offers a specific way to tune the amt3000 but i plan to experiment with other transmitter kits—and eventually try doing some homebrew stuff—and i want to learn more general methods of tuning antenna systems.
what about swr meters? are there any for medium wave? would one be useful for tuning a part15 antenna system?
