Hey, I have a project idea for someone with a good reference library stuck at home after surgery or otherwise with time on their hands--Build a coil cross-reference table. My ideal table would have columns labeled FACTORY COIL ID, FACTORY COIL SPECS, PROJECT EQUIVALENT, and NOTES. So an entry in the table would go something like this (hypothetical, entirely fictitious example...)
COIL ID: B&W HDVL-10 FACTORY COIL SPECS: 6 turns 1/8' copper tube, 2 inches in diameter, spread evenly over 5 inches, with link.....etc. PROJECT EQUIVALENT: 7 turns of #12 solid copper wire, 1-7/8 inches in diameter, spread evenly over 4.5 inches with link...etc. NOTES: Factory coil specs from actual measurements. Project Equivalent data from 1954 ARRL Handbook, page 258. HDVL coil uses 5-pin jack bar with banana pins evenly spaced from ends. Equivalent coil made by Hallicrafters as their part number C450B for the HT-4 transmitter. Also has military equivalent 163-7321D-639 made for the BC-610 transmitter. Or whatever. You get the idea. The PROJECT EQUIVALENT data comes from looking at projects where they specify a commercial coil but also give coil winding data... Having this table would allow anyone short a coil or two to quickly make one up. Anyway, probably a bonehead idea, and maybe everyone already has one of these tables. But I don't. 73, Don Merz, N3RHT -----Original Message----- From: Arthur E.
