Default Band Spreads in Vintage radios

I find it rather interesting that certain sw vintage radio you have a
knob called Band Spread. Take the Hallicrafters SX-100. It has two
large half moon windows. The one on the right is for the Band Spread.
Now their is another knob to select the band, but you still have to tune
in on the Band Spread knob. Then you fine tune with the left.

I guess thats how that work. It can get a little confussing. However,
I think some how their is an advantage to this.

The Hammarlund 170 does not have this type of Band Spread. I think the
Hummarlund 180 and 180 ac has it. Is that correct?

It would really be cool if their was a way to add a frq counter.

SR!



The band spread is used for the fine tuning. On some communications
receivers there is a mark on the main tuning dial to set it to for the
various ham band frequencies, and the band spread will be marked with
the ham frequencies only on a much more spread out scale than the main
tuning scale. When you set the main tuning on the mark for the ham band
then the band spread should read correctly for that particular ham band.
