Hi everyone,

I've been interested in radios and how they work since I was a kid --
I had a crystal radio kit and a RF-2200. Recently I started building
radios and have been having a blast. Please keep in mind that I
am very newbie.


[tale of woe deleted]

I'd start again with a simple Hartley oscillator using a tapped toroid (you
don't need a choke). Get the basic oscillator working (a scope helps) then
add a buffer stage.

Forget about getting the oscillator and front end tuning to track properly
at this stage, use separate capacitors. When you get the thing working
properly you can sort out the tracking.

73, Leon
