This reminds me of Major Edwin Armstrong's "saying" he used so much, especially when he was told by Crosby that "wideband FM would not be practical".
Amstrong retorted to himself with "It's what we know that ain't always so!" (or something very close to that.) I have seen phenomena regarding grounding of marine transmitters and presence of RF in strange places where it should not be MANY TIMES. Also other things regarding feeders and antennas on ships that would not work as advrtised, or as the engineers claimed they would! I still have one occurnce of something that happened during trouble shooting of a 35' shipboard vertical with a "top hat" that occurred on the 425-515 Khz. band nobody yet has given me a valid explanation for. The "experts" are not always even close to right all the time! 73, Sandy W5TVW ----- Original Message ----- From: "Ron D'Eau Claire" <r...@cobi.biz> To: "'Elecraft Group'" <elecraft@mailman.qth.net> Sent: Wednesday, May 27, 2009 10:00 PM Subject: Re: [Elecraft] OT: transistor theory flaw > Tnx Mike. > > It reminds me that vacuum tube theory wasn't understood for many years > after > they were developed.
