Upon pedantic reflection, I guess I was unfairly harsh when lampooning the lack-of-reach of the KLSR signal, back when the educational-band FM station was still "propagating conversation at the speed of light" until the Lindbergh School Board finally gave up* on the money-sapping operation circa 1986.
But THEN this afternoon I remembered a positively glorious fact I first learned from Newsweek, when Voyager 2 was "gravity-assist" slingshoting its way by Uranus** on its way to its breathtaking rendezvous with Neptune in 1989: that the transmitter on Voyager 2--as well as its sister transmitters aboard Voyager 1 and Pioneers 10 and 11--now are at the furthest edges of our solar system (the so-called "heliopause"), or already beyond, into the comparative void of interstellar space***: each are (I believe) STILL beaming back data at 186,282 miles per second toward the Jet Propulsion Laboratory in Pasadena**** (powered by their plutonium-decaying-fuel mini-reactors), with each pumping out its respective signal with all the radiating oomph of...only FOUR red-hot watts--less than half KLRS's meager, static-saturated signal, and even a tad less than your standard trucker's 5-watt Citizen's Band radio!
(How NASA engineers manage to get THAT kind of distance--all four robots were at least 10 billion miles distant by 2021, if memory serves--out of those ultra-faint signals is far beyond my physics-challenged cranium; all I know is, the 10-watt KLSR signal's mileage from the FM transmitter atop Lindbergh High indeed sure did, uh, "vary", as the TV car ads always so scrupulously caution.)
* Of course, I've always PRESUMED that the Board just figured KLSR was pointless once they didn't have that radio phenom Bryan Styble behind the microphone or as Program Director anymore.
** Kindly don't bother recycling once more that vulgar variant-pronunciation joke you heard the class clown utter in middle school science class.
*** Which NONE of these four amazing mechanical testaments to painstaking post-Englightenment reasoning and experimentation--shall EVER exit, moving into interGALACTIC space...for the simple but oh-so-immutable fact that none of the quartet are moving at anywhere NEAR the escape velocity for objects of ANY mass at our distance from the center of The Milky Way galaxy, i.e., approximately 550 kilometers/second.
**** That would be California, not Texas...though oddly enough, my wendingly-wacky showbiz career found me employed in BOTH Pasadenas, the latter-listed of those same-name suburbs back in 1979-80, and then the former in 1980-81, after "goin' Hollywood"*****, as that terrific Bing Crosby tune sampled in "That's Entertainment" so melodically phrased it.'
***** Uh, that's California, not Florida...though I HAVE visited that quite charming Miami suburb much more recently than I have last seen its vastly-more-celebrated civic namesake out West.
