Hello LF'ers,

Two 500 watt Class D amps combined. The output transformer of the
combiner is now an auto transformer. This feeds, via RG-213 to
outdoors, where an isolating transformer, that is a conventional
primary / secondary transformer with taps for impedance matching then
feeds my loading coil and then the antenna. Can I wind the isolating
transformer as a 1 : 1 and do impedance matching (which changes with
weather / foliage growth) indoors using a tapped combiner auto
transformer? I want to change the impedance matching / isolating
transformer anyway as it runs a bit hot on long TX sequences. I tried
an auto trans former as the impedance matching one outside, but had
serious RF into the mains causing various issues, a conventional
isolating / impedance transformer fixed all that, so I assume it needs
to stay, even as a 1 :1 ? Thanks.
