What's the story, here? The world is waiting! That snow and high winds shouldn't deprive us. BTW: Maybe if I can get the loop article figures to you it would help. I'm working on it. If you have a BFC (no!: Big Ferrite Core) just drop your 50 ohms to ~1 ohm, at the base of the loop, with a 7T primary. Place your resonating capacitor bank in series with the 1T core secondary and the loop wire. This amounts to a series resonance connection. May have concede a few watts to stay within the voltage limits of your mica capacitors but......... what's a few watts amongst friends; right?
