Beautiful! A Permeability Tuned Oscillator. No need for a fancy variable capacitor — that brass screw moving into and out of the coil varies the inductance and the frequency. Collins style. <\/b><\/div>\n

I also wanted to send you a shot of what today’s project has been. It’s WA6OTP’s PTO.

This is a 40 meter PTO that covers the entire 40 meter band.
A little Q dope secured the windings.
