Simple Hartley Oscillator

I decided recently that RF was a field I had very little practical knowledge of. I know the basics, the methods and the general ideas, but I’ve never actually put together a circuit other than a pre-purchased kit.

Thanks Alan Yates and the guys on twitter I set out to be a simple RF oscillator. I also really wanted to build something using the “Manhattan” construction style.

You can see above I’m using the CRO probe to inductively couple with the tank coil.

I’ve still got the circuit bouncing around my desk, I’m going to attempt to build a Direct Conversion receiver with it when I have some time.
