We have lift-off! I soldered on some lead wires, and inserted the proto-board circuit into the radio. I tried inserting a video of it playing for a few seconds, but apparently I cannot upload videos. Anyway, I captured a video of the radio tuned into 100.9 KTSO (Tulsa’s Soft Oldies) for just a few seconds.

So far as I am concerned, the range of adjustment is great with the 82 pF fixed capacitors and the 20 pF trimmers. My next step will be to start on a PCB design to tidy it up.
