Just out of curiosity...

The 10m, 15m, 20m, 40m, and 80m bands are marked on the main tuning. But
where would you set the main tuning to properly use the bandspread for
each
band? I am particularly curious about 40m and 80m, both of which have two
bandspreads.

And why is there no bandspread for 20m?

That is an oddity on this receiver. 20 meter bandspread
scale is to the RIGHT of the 15 meter BS scale. They
are rather small scales. If you look closely, you can
see where the 15 meter scale ends, a gap, and then
the markings for 20 meters.

80 and 40 meters have very wide BS, with 5 kHz
markings. There are two set points for each band
on the main tuning scale, indicated by small circles.
40 and 80 meters each have two BS scales.
The trick is in precisely setting the main tuning for
good calibration on the BS scale. The dial pointer
width is equal to 50 kHz. I think if I ever used this
RX on the air, I'd make an HF converter that would
use the 80 meter or 40 meter scales for the upper ham
bands, that would also take care of the image problems.
