Awww gee - I thought HE made antenna tuners so one could present a 1:1 load
to the transmitter so one could tune up their amp into a 1:1 dummy load and
just switch over to the tuner /antenna without having to touch the amp and
avoid the endless tuning on air, esspcially on the DX freq. Some people
however never did get the message.
