No Static at All – 2

My parents’ General Electric 408 AM/FM Radio from 1950, the year they were married. Dig that Atomic Age tuning dial!

My bedside radio as a kid in Connecticut was my parents’ old GE 408 that I rescued from the attic. It was introduced in 1950, only a few years after the FCC’s mandated change in FM frequencies, from 42-50 MHz to 88-108 MHz.

Edwin Howard Armstrong invented and patented FM. Armstrong had a very difficult time getting broadcasters to embrace his cutting-edge technology, despite the fact his inventions had made AM broadcasting possible. So Armstrong started his own radio network.

“In the war’s final year, big industry, led principally by RCA, was working quietly behind the scenes to undermine FM’s position… The interests aligned against FM were concealing a strong poker hand, and they planned to play their cards as soon as the war ended.”

The war stopped Armstrong just as FM was gaining in popularity. Then the post-war frequency band change rendered his FM radios obsolete. His consolation prize was FM being mandated by the FCC for TV sound.

No Static at All – 1

Something I failed to spot in 2015 was the 50th anniversary of the Master FM Antenna installation on top of the Empire State Building. There was a light show, commemorating the date, synchronized to Steely Dan’s “FM”.

The song was from the 1978 movie of the same name.

Ironically or not, we played “FM” on the AM station where I worked. In 1978, for a $15/week raise, I became a one-man news department, like Les Nessman on the fictitious AM station WKRP in Cincinatti, which premiered that same year. Loni Anderson was a breakout star on the show, but for me the one to watch was Jan Smithers.

That Number Again

Yesterday, I commented that my 5,000+ blog posts aren’t as many as stars in the galaxy. They are, however, as many as the stars that can be seen with the naked eye at night. So said the late physicist Richard Feynman.

Feynman was one of the young scientists who developed the atomic bomb. You can read about his time working at Los Alamos in his first memoir, Surely You’re Joking, Mr. Feynman.

Caching Out

An update somewhere in the software stack changed the caching code, and new posts were taking hours to appear, so I have disabled the WordPress cache. This might slow down the site, but that’s preferable to having a stale presentation.
