Change of FM band frequencies

[Chris Hall]

To make a long story short, David Sarnoff of RCA in collusion with the FCC to screw Edwin Howard Armstrong to protect the standard (AM) band by keeping his superior (FM) transmission system from gaining ground with the public.  This made all old band FM receivers obsolete, he then tried to screw him out of royalties on new band RCA FM receivers along with royalties for FM mandated TV audio. If you want the full details I suggest getting a copy of the PBS documentary “Empire of the air”  TV at its best. Longest patent and royalty suit in US history, he finally won 40 years after he died.
