Recently I provided copies of the ALLIED Handbooks and slide rule for coils. I found out today that ARRL sells a slide rule inductor calculator. Upon visual inspection, it appears to be an updated version. So those wishing a calculator can order one from ARRL for about $10 plus shipping, or make your own and buy two Starbuks coffees. :-)
