Hello all.

I feel foolish posting this but have come to my wits end with this radio.  The BC band works fine, but the 3 shortwave bands will only pass a very strong RF signal from a generator and receive nothing over the air.  I verified that each band is oscillating and that the SW portion of antenna 1 (shared with the BC band) and antenna 2 (two SW bands) have the expected continuity and are connected properly to the band switch. I also verified the oscillator connections and continuity and tried different oscillator tubes.

Can anyone suggest something that I may be missing?  Schematic attached.

Cheers
