Just checked the oscillator with a Zenith 1000. With the Zenith set at just below 7 MHZ I tuned thru the SW band and found the null at Just above 7 MHZ on the Philco, actually around 7.1 MHZ. Interesting too is that if I tapped on the tuning knob on the Philco I could hear the thumping in the Zenith.
