Didn't the HW101 tuning cap have a built in reduction drive as well? about 1.5:1?

Yes. I don't know the ratio, but the cap has reduction gears built in.

There was an excellent article that ran eons ago (73 Mag?) that showed how to ad a swan dual drive to the HW-101.  I knew two hams who did the mod and it was a vast improvement over the stock Heathkit dial drive,

Found a Siltronix 1011x that had been completely destroyed save for some tin and the dual drive. I did just that. It is a bit of head scratching and would not have been attempted if the Heathkit had not been dropped on its face. I was happy with the result .

I considered a microwave oven magnetron and a 4' dish as a drone-killer. The ERP would be on the order of a hundred thousand watts or so. ~anon
