Hi Mike, There was an article in an issue of QST (when it was still of the small-format, I believe), as well reference made in the large-format HANDBOOKS, regarding inserting a small coil in series w

Oops...! What I MEANT to say, was 1/4" edge-wound copper ribbon, NOT 1.4"...! A coil of those latter dimensions would be deserving of MUCH more than just a PAIR of 813s!!! ~73~ de Eddy VE3CUI - VE3XZ

Because the tuning on the lower bands was radically altered with it in, far & away removed from quoted "text book specs" for a pair of 813s in GG... Makes sense--good idea. Guess I shoulda considered
