Useful Dead Technologies
Monday, January 31st, 2005A co-worker just emailed a link to Useful Dead Technologies, a sardonic piece, bemoaning the loss of the tried and true to new technology.
Here’s one complaint:
Volume control knobs
You’re driving down the road and that song comes on. You know the one, it really rocks and you must crank that sucker up.But there’s no crank any more. You have to take your eyes off of the road to find the one button on the fifty buttons to turn the damned thing up or down. Thank God they invented cell phones so you can call an ambulance after you wreck your car trying to turn the volume down to answer your cell phone!
And if you want to adjust the tone, balance, or rear fade, forget it. You’re either going to have to stop the car, or get a passenger to do it for you. If, that is, he or she can find the owner’s manual to figure out how to.
The old technology used knobs. There was a volume knob on the left, and a tuning knob on the right. Behind the volume knob was a tone control, or two tone controls (treble and bass). The knob on the right changed the stations, and it had a knob or two under it controlling balance and sometimes fade.
Some less stupid car radio manufacturers still use knobs, albeit digital knobs. But even these are less useful.
Old fashioned analog potentiometer knobs not only could be used without taking your eyes off the road, they were far more precise. My car stereo (with its volume buttons you have to look at to adjust) has 25 discrete volume levels. Some stereos have 50.
The old fashioned analog volume controls had an infinite number of levels. They were analog. If you’re at the fringe of a reception area and the weather or whatever has caused the signal to drift, you could precisely tune it with your radio’s analog variable capacitor. Today if (for example) KSHE 95’s 94.7Mhz drifts to 94.8 and you’re north of Litchfield (about 50 miles), you’re out of luck, as you can tune to 94.7 or 94.9, but not 94.8200032010023445 like you can with an analog tuner.
Here’s the reverse: I live within a mile of a huge radio tower, WRUF in Gainesville. It broadcasts PBS TV and AM/FM Radio. The only way I can listen to radio stations which aren’t Rock 104 is if I have a digital tuner. All of the analog radios are bled into by the tower. Forget about AM. My 2.4GHz wireless headphones pick up the VHF TV signal when the base isn’t tuned or is off. The tuner for that signal is analog as well and if I don’t have it exactly correct, I get PBS while I’m working in the yard and want to jam tunes! Even then, as I turn my head or go behind the shed, instead of a fading signal or a bit of static, I get Arthur and the Berenstein Bears!
Although, I must say during the early days of digital radio, I preferred analog, because the LEDS were always burning out or the innards fried and whoop! No more radio. The new stuff seems to have improved greatly, as is usually the case with consumer goods.
