80M LC CircuitĀ 

It was easy to get the LC circuit to work, as I have two excellent components. The roller inductor is a Palstar inductor and the variable capacitor is from an Ameritron ATR-30 where I had to constantly fix the edge wound roller inductor, so I junked it and am using it’s parts. They both fit at the top of the box and will easily…

Calculating the 80M LC Circuit

I was able to find an online calculator that will give me the circuit components for an 80M LC tank circuit: http://www.ham-radio.com/lc.html I happen to know that my Palstar roller inductor goes up to at least 20 uh, and while my giant Palstar variable capacitor goes up to 450 pf at 4.5 kv, I’d like to try to use a smaller E.F Johnson variable…
