TV -> D-Sub converter possible?

Edwin Armstrong had started his Yankee FM radio netowrk just before WWII and FM broadcasters had been allocated use of the 42-50MHz band for their use. (You can still find the occasional rare pre-war FM receiver with those frequencies). "General" David Sarnoff of RCA at first didn't understand what FM was (he thought it was some sort of a filter on an AM radio) and then became alarmed when the relatively noise- and interference-free FM radio began gathering popularity. Sarnoff decided (and got the FCC to approve) that using FM as the audio portion of the NTSC signal was best for the fledgling TV industry. Sarnoff offered Armstrong $1 million for non-exclusive license for FM. When Armstrong refused, Sarnoff got angry and refused to pay any fees at all, and got other broadcasters to go along with RCA. Armstrong, initially a wealthy man, was worn down by RCA's bevy of lawyers and endless appeals and broken financially. He committed suicide and Sarnoff offered his widow $1 million to settle claims. Largely due to Sarnoff's vindictiveness and influence with the postwar FCC, the prewar FM band was moved to 88-108 MHz and TV channel 1 designated as the new owner of the old FM band. This, of course, made all of the receivers sold by Armstrong useless. Channel 1 proved to be less desirable than other higher-frequency channels, due in part to the better long-distance propogation characteristics, resulting in more interference. Technical innovation the American way--racketeering, legal maneuvers and dirty tricks. My uncle used to have an old Stromberg-Carlson set with the two-band continuous tuner that would tune Channel 1. --Chuck
