Especially a diagram (or crude drawing) of how things are done would be appreciated. A NEC model would be fantastic, but I'd be more than happy to prepare that from the crudest drawing anyone could send me, and then make it available to everybody else :) -- All rights reversed. _______________________________________________ UR RST IS ... ... ..9 QSB QSB - hw?
