[Elecraft] OT: Aircraft radio FM

[Sandy Blaize]

Yes I read all about RCA screwing Edwin Armstrong on wideband FM.  David 
Sarnoff had connections with the FCC to eliminate the old FM band (pre war) 
and have the 88-108 region allotted  which made all of Armstrong's equipment 
obsolete.  Also RCA claims to have "invented" a new wideband FM system to 
work around Armstrong's patents.  Armstrong's wife finally managed to 
finally win out over the manufacturer's and RCA in lawsuits long after 
Armstrong jumped out of a hotel window in disgust and near broke from legal 
costs.

I remember FM "heralded" after the war but nothing ever overcoming the AM 
broadcasters until years later when all the principals were dead by then!  A 
sad story of corporate greed and corruption.  (With the help of the FCC back 
then, a lot of whose engineers got plum jobs with RCA!)

73,

It would have to come from the ICAO through the ITU before the FCC would
consider it.

Digital TV and FM came about because of lobby pressure on The Congress
(money talks).  I can't foresee a lobby for Aeronautical AM.  Very few
technical "changes" start with staff recommendations.
