Thank-you Cary – that’s very kind coming from
you! After my last post, I recalled another good example of how the neural sub-conscience may affect our [my] appreciation of an emblematic 60s song heard on AM versus FM. Last spring [not long after WDJO’s debut], I was in the area for a week and decided to drive to Cincy to lunch with a friend. Early that morning, the FM band was open, and I was able to hear WLDE [FM] Fort Wayne on my father’s nice Sangean “Wooden” table radio connected to an otherwise-unused outdoor TV antenna up 40-feet. WLDE is an exception to the “oldies sound like crap on FM” paradigm – their audio is aggressive but judiciously-processed, and the songs are ever-so-slightly “hyped” [about 1.5-2%]. Jonathan King’s
“Everyone’s Gone To The Moon” appeared [a favorite] – I found myself thinking: “good song, that’s nice” and went about my business.
Three hours later, I was in my father’s Buick on I-275 northwest [at the Regan interchange] listening to WDJO. Jonathan King re-appeared... Instead of hitting the band switch to WGRR [because I had heard the song earlier] – I reached down and
cranked that Delco up; found myself really enjoying the encore; and realizing that it was [
somehow] more-compelling on 1160AM. I swear to you – this was NOT some aging broadcaster’s attempt to rationalize the alleged deficiencies of AM radio – it was a genuine phenomena!

You’ve just tagged the “Trinity” of AM engineering, Cary! All TOO often. TOO many marvel at their Star Trek-ish Omnia AM box firing a reasonably-modern rig – and think they have all the bases covered. TISK-TISK! [Recalling a political statement regarding the economy]
“IT’S THE ANTENNA, STUPID!” I was fortunate to have a contract engineer [a Harv Rees “disciple”] who worked with me on an AM upgrade in the early-90s that preceded a flip from
“AM Only” [off the bird] to locally-programmed Oldies. NO transmission hardware [with circuits] changed... NOT our stack of CRL components fed via carefully-equalized Telco by an Aphex Compellor – NOT our impeccably-maintained decade-old 1kw Harris MW-1 rig [we even flushed-out its notorious IPM despite the lack of AM-stereo]. Save the original steel on the tower, the
antenna was
completely rebuilt... New Andrew line; a custom-designed folded uni-pole skirt [designed to achieve “flat” system impedance/bandwidth and low J-factor [not the
mythical increase in field-strength]; and a
HOME-BREWED antenna ATU in a new Kintronics box – literally built on the floor of our AM control room. Oh what a beautiful sight that finished box with its shiny-new Delta base-current meter was to behold! ‘Shame it lived behind an eight-foot stockade fence to keep people and grazing cattle at bay. While the prior facility sounded good and coverage was a bit beyond the norm – we were entertained by the challenge to be better... The result was MUCH BETTER! Audio quality, density, and “impact” were off-the-scale [causing one to fondly-appreciate his choice of the radio profession]. The
180-watt [ND] night signal
bettered the heritage AM in town with 500-watts [DA] at night – and they paid dearly for it come acquisition time ;D
On a Monday morning, we hit that big green button on the improved facility and inaugurated our Oldies format with Lighthouse’s
“One Fine Morning” followed by Chase’s brassy
“Get It On (In The Morning Now)”, then Giorgio’s
“Son Of My Father” [for my engineer dad and I]. The titles were chosen for their message - but also their sonic quality. I was at home listening on a Carver TX-11b wideband AM tuner on my living room system... Taking a line from
“The Shawshank Redemption” – “I nearly soiled myself”

It WAS the
ANTENNA, stupid!
