I removed the RF chassis and have checked the antenna transformer coils.
The BC band transformer has a bad primary. There's no continuity between either end and the center tap. I suspect the problem is at the center tap.
How is the primary wound? I'd kind of like to know before I start unwinding wire.
I scraped the wax off of the primary with my finger nail. I expected to see some sort of discontinuity in the middle where two haves of the coil join. Maybe it's small and I missed it. I'll clear off some wax at that end with the heat gun to see what I can see.
It wasn't fun getting the coil out and it won't be fun replacing the capacitor sandwiched between the two band switch wafers either.

Can't think of anything witty.
