Hi! Note your interest in Xtal sets. As a young kid 60+ yrs ago 'designed' by seat of my pants my own Broadcast Band rcvrs using huge individually-tuned multi-loop antennas with loops spatially coupled for simultaneous, empirical near-critical coupling with modest azimuthal directivity. Tuning an adjustment nightmare, especially so since I didn't know let alone appreciate the underlying mathematics. (Long after the fact, I'd guess radiation resistance limited Q's to the 500 - 800 range with 3-db bandwidths in the order of 2 kHz and skirt selectivities of maybe 18 dB/octave -- but interference was pretty horrendous.) Still have happy memories of receiving Chicago station in Western Massachusetts (once) -- a distance I guessed must have been near 1200 miles. Would get WWVA (Wheeling, W. Va) fairly regularly. Regret I've never seen anyone else to mention let alone try the scheme. Don't particularly regret stumbling half-asleep into Mrs. Daugherty's Latin I class totally unprepared, but try to make up for it by trying to work my way throughthe Anaeid.

Wow - great library. I am adding to my reading list from it.

John, what does the "friends" concept mean to you? What functionality does it possess? The LT help resources do not even mention it. Thanks.

Thanks for exposing me to LibraryThing. I joined today and added 17 books (atlases).
