<Just a note that I've moved my coil inductance and Q calculator to a new

<Check the version number in the link. If it's new, click to download.

<COIL 3.22 has a number of improvements. It features an automatic Q 
<optimizer, handles coils made of Litz wire, provides an RLC model useful 
<for broadband antenna analysis, lets you explore coil properties with 
<the mouse wheel, and is even more accurate. See COILS.TXT for updated 
<accuracy validation figures. See READ.ME to overcome some Windows quirks.

###  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.
