Model 70 air cap ground strap.
#22

<Thing is, it seems this radio was designed to track 260 below the band, not above, and the difference is still 260>

I think what you will find is if you are able to get the oscillator to run at the low of the band at 310kc with dial set at 550kc when you try to get to the high end of the band 1500kc the oscillator won't tune high enough. You'll have too much L in the circuit. If you remove turns to get up to the high end then the low end suffers by loosing the bottom 50 to 100kc. In short the tracking will be poor.

I was down in the basement in my dad's
workshop. Perusing his Sam's Photofoacts
Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.
Circa 1966
Now I think I've got!
