<COIL 3.22 has a number of improvements. It features an automatic Q

### Brian, it would be even more useful, if it would handle larger diameter
tubing coils.
The biggest it appears to handle is 1-0. And thats way smaller than the
.375 inch OD
tubing coils I tend to use..for some applications, like 40m loading coils.
I use .375 tubing
simply cuz when ends are flattened, I can punch a .25 hole in each end..and
use .25-20
hardware. The software should be able to handle at least up to .5 inch OD
tubing...
and bigger. The original coil program from eons ago, easily handled .375
tubing.
