Wpwt
I was on both WKDU and WPWT from 1978-80. The two stations shared time. WPWT had the frequency from 2:15 pm to 9:55 pm, Monday through Friday, and WKDU the rest of the time. There were occasional 'swaps,' such as when WKDU needed to air Drexel basketball games. (WKDU was/is owned by Drexel University and debuted, as an on-air station, as I recall, c. 1969. [It was a campus carrier-current station prior, as WXDT, if memory serves correct.]
WPWT was owned by the Philadelphia Wireless Technical Institute (at 1533 Pine st., Phila. - [address given above is incorrect]) came on in 1950 and had the frequency exclusively prior to WKDU coming on. WPWT had a 250-watt transmitter, but a negative-gain antenna (shaped like the ring of a basketball hoop!) that brought its effective radiated power down to 180 watts. Because WPWT's tower wasn't very high at all, the signal was blocked by the tall Center City buildings to the North, so reception was pretty much limited to West, South and East. WKDU was only 10 (yes, a mere ten) watts at the time, but because its tower was atop a tall building in University City (Powelton Village) its coverage area was much greater.
Bill Barthe was our Program Director at WPWT and revamped programming in 1978. We started with a Top 40/Rhythm mix (plus one jazz show and my oldies show) and then we converted to an all-disco format (the first and only non-commercial disco station in the country at the time), which proved immensely popular. I also continued my oldies show on Friday nights which drew tremendous response and song requests galore. (According to P.D, Bill Barthe, WCAU-FM, which at the time was one of two big disco stations in the city [the other being WZZD] used to call him to find out what kind of response we were getting on certain songs to advise if they should add them to their playlist! A few of the jocks from those stations even came to visit us.) [For more details on our air personalities, etc., check out the website,

At the beginning of 1980, as disco was quickly fading, we went to a Top 40 Format (plus my oldies show). Again, we received numerous, numerous calls that people loved us!
Callers were saying that we even far better than WIFI, 92.5, the powerhouse local Top 40 station at the time, right next to us on the dial. People would discover us by accident, while looking for WIFI, and said they liked us better!
Getting back to WKDU for a second, 'KDU also had great Top 40 programming on Saturdays in 1978, owing to Program Director, Santo Cannone, and I am thankful and grateful to have been a part of that lineup.(I was partnered with Sab ["Supersab"] Michael. We were originally on Saturday Mornings, 6-10, and then moved to "Prime Time," Saturday Nights from 6-10.) [Sab and I both broadcasted, concurrently, on WPWT, as well, but with separate shows.]
