Back THE GREAT AMERICAN DESERT
Sound Waves Through the Night
 


Balanced on a point, the three-sided metal frame latticework of tubular steel triangles rises almost 500 feet into the prairie sky, red, then white, then red again in fifty-foot intervals, three sets of six thick steel guy wires pulling against each other, circling the tower in one hundred-twenty degree arcs, taut strings of an electronic instrument humming in the wind, climbing to the top in fifty foot increments, flaring up in groups of three from anchor points fifty and one hundred feet out from the base. Paired red lights half and three-quarters of the way up, with one on top fading in and out in four-second cycles, and in and out again. A delicate balance prevailing over gravity and weather through a precise blend of physics and geometry in a harmony of ephemeral beauty, like some perfect tripartite mirrored skeleton. The unseen waves radiate outward for miles, sometimes bouncing off the atmosphere hundreds of miles farther.


Driving through the dark in the southwestern reaches of the San Luis Valley, the tape runs out and I switch over to the radio. Nothing on the FM band so I try the AM band. Amplitude modulated, crackling with static, farm reports and high school scores.


Dark in the control room with red lights, dials and guages beaming up from the control panel, five miles out of town beneath the antenna higher than any structure for miles and miles around. The disc jockey pops in a tape cartridge for the next commercial -- car dealer, feed store, main street restaurant -- starts the next record, talking over the first notes, the introductory music that begins the song, filling in with his voice, his radio personality, head tilted, talking to the air, animated, seeing his listeners in his mind, headphones feeding his own voice to ensure that perfect pitch, tone, timbre and resonance delivered with practiced pacing, ending precisely as the singer enters. Then he switches off the mic which kills the red light over the control room door. Out of the control room. He records the numbers off the broadcast unit ensuring for the Federal Communications Commission that it is broadcasting within its assigned frequency and strength, listening for the song he knows by heart to begin to wind down requiring him to run back into the control room, cue up the next record, play a commercial or public service announcement, read a promo. Then out to the front office for stale coffee, bathroom break and a call home. Three-minute sprints. Check the news wire teletype. Only a steady low ringing, no urgent clanging that might require him to interrupt the regularly scheduled programming. Sports scores, more on earlier world news, repetition of US and Colorado news, nothing to satisfy anything more than his own idle curiosity, filling the space until he must do more, change the record, play a commercial. The continued quiet from the news wire means there is no need for him to perform this night in the public trust; no floods raging down the valley, thunderstorms long faded for the night, no tornadoes or national emergencies, as the song winds down.


Top of the hour, announce the time, the station's call letters and frequency, and switch over to the news wire service, striving for a seamless segue that will perpetuate the illusion that the national news anchor is in the same room, in this, the theater of the mind. Four minutes after the hour run a commercial and a promo for the station. Read the local news written at noon by the sales manager/news director, maybe add a clever quip, then back to the musical format that assures the community with a lulling predictability.


As the tower recedes behind me the signal fades, pulsing static grows, underlain with layers of almost heard dialog and music, as other frequencies bleed over the signal. I scan the dial for the next strongest signal. Dialing it in, another disc jockey back announces the last song and reads local sports scores in the dark of the control room. Two more hours on this shift and he can shut down the massive electronic equipment, lock the door to the small cinderblock building, head back to town and drive to his home past darkened houses on the now even more quiet streets.
