What's the general feeling about toroidal dust iron cores in tank
circuits? I know some manufacturers seem to use them just fine at the
1500 watt level: I've always felt a bit dubious, but that may be just
innate conservatism. I've used them at 100 watts OK in a professional
transceiver, but what are the big ones like at 1500watts with up to
2:1VSWR?
