Can someone please explain the leads of this variable capacitor and how to hook it up?
I have never used one and I want to make sure I get this correct.


Thanks

It's quite simple, G is the ground, and the other two are the two seperate variable capacitors, 160pF and 60pF, if you join them together you get a single variable of 220pF (which is probably more suitable for MW radio tuning)

Ok, thanks for the reply.

So to create a variable capacitor from 0 to 160pf where would I run the wires?

A wire from G to ground and a wire from O to the circuit?

I'm sorry but I am still confused.

Thanks

For 160 pF you would connect to G and A. G to ground preferably to lower parasitic coupling to other things.

Yes you would.
