Yup.
My 949D Versa Tuner was OK at 100 watts, 160 meters. But when I upped the power to just 200 watts,
the dielectric tucked around the capacitor's shaft and the steel chassis arced and made like
Cheech and Chong...up in smoke.
I ended up building a giant manual matcher for just 160 meters. A 35 micro henry roller inductor and two
4,500 volt, 200 pF air variable capacitors from RF Parts.
I'm having tons of 160 meters Morse fun.
And by the way, I found an Ameritron AL-811H on eBay. It says for parts or not working. I don't think the
individual knows what he is selling; a non-ham. He said, "I couldn't get any thing out when the exciter was
connected." I ain't never called the transceiver an 'exciter'. Hmm....
Current bid at $271.00. We'll see.
