Today’s featured photo of the day! The feature is: Radio

For the month of November, I will be featuring radio transmitters and antennae. Here is today’s featured photo, to commemorate with the industry of radio’s 100th anniversary of invention.. Here is a photo of a view of the Chicago skyscraper landscape with a sunset in the background on a summer evening from out at the end of Navy Pier at the ChicagoFest event in the summer of 1982. The central subject of the photo, the then John Hancock Center Building now called the 875 N. Michigan Avenue Building, Chicago, Illinois–which featured in those days a lot of radio and television transmitters and two very distinct antenna. The building was built opening May 6, 1968, and is 100 stories tall, making it in those days the second tallest building outside New York City and Chicago’s tallest building until the opening of the then Standard Oil Building, now the Aon Center in 1973. The 98th Floor Observatory is located on the 98th floor Where you can look past the Wisconsin and Michigan borders all in once lookout. Radio always played a very great role in the John Hancock until more recently when the building did not upgrade its equipment for television broadcasting to the updated digital signals that went into effect starting in 2007-2008. The final phase of turning to the television band completely to digital will be next July when all low powered stations nationwide will need to be transmitted on digital. Seems like it is not a big deal…Tell that to Weigel Broadcasting, which owns Me-TV-FM! They transmit on the frequency of 87.7 MHz which is not officially on the FM dial. It is actually the original sound channel on original TV’s VHF-Low channels 2-6 on channel 6, where TV was right before the FM band. Weigel is working on a system whereby they are going to attempt to universally “keep” the 87.7 signal, have it come in on your present analog radio, and be “digital”–all of which needs to be completed and fully approved by the FCC by the day July 13, 2021.

Radio is technology of modulating, signaling and/or communicating using a radio wave, which is an electromagnetic waves in the low frequency just above the sound wave between 30 Hz and 300 GHz. The electronic wave is generated by a transmitter connected to an antenna which radiates the wave, and tuned by a radio tuner connected to a receiving antenna. Radio is used in communication, television, radar, navigation, remote controls, remote sensing and other variety of other applications. In the whole spectrum of energy, it all starts on the low end with

    • Sound/resonance waves
    • Radio waves
    • Microwaves

Then the spectrum turns to rays as the perpendicular lines start to radiate in conjunction with the wave-fronts of the actual light or ray, and that points in the direction of the energy flow Leading into:

    • Infrared rays
    • Visible light rays
    • Ultraviolet rays
    • X-rays
    • Gamma rays
    • Cosmic rays

Photo taken with a tripod mounted Nikon FE camera through a Vivitar 70-150 zoom lens zoomed in at 150 mm, filter=polarizer, Aperture=2.8 f/stop, shutter-speed 1/8th second, loaded with Konica ISO (ASA) 100 Color 135-20 Negative Film processed with C-41 Processing Chemicals, and a Type C Print using the RA-4 enlargement paper process, onto a 4X6″ semi-gloss print. Date – August 1982.

Another fine photograph and facts about the John Hancock Center to follow very soon to celebrate the anniversary of radio!!

  1. This is a realy cool and interesting article. I have lived in Chicagoland my whole life. When The Loop (WLUP) was up in the Hancock bulding in the early 90s and Danny Bonaduce was on the air at night. My girlfriend and I got to go up there and we met Danny. Thanks for this post!
