[BC] Determining a coil

[Alan Gearing]

Ed:

Do the coils have any readable part numbers on them?  I've got parts 
lists for most of the major coil vendors (current and past) and could 
probably give you the current/inductance values.  Otherwise, I have a 
dos program that will take the coil diameter, wire diameter, wire 
spacing, number of turns and give you the inductance.  Or if you need to 
design a coil you can input the desired inductance or reactance and 
frequency and it will tell you the required coil dimensions.  The 
program is in the public domain and I can't recall where I downloaded it 
from.  Contact me off list and I can send you the .exe file.
