Analog FOREVER! Menus are For Restaurants! Hardware Defined Radio! Chris's PTO
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.

I also wanted to send you a shot of what today's project has been. It's WA6OTP's PTO.
I bought the plastic tube/screw/bracket from Jim and I provided the rest.
This is a 40 meter PTO that covers the entire 40 meter band.
A little Q dope secured the windings.
