September, 2007.
The Pine Tree Road Site houses three of the Citadel Lansing FM transmitters.
As one of the tallest towers in Lansing, it is a desireable location for
many other users of the radio frequency (rf) spectrum.
The top section of the tower is a monopole that supports
a four-bay FM antenna for WITL-FM analog
and a three-bay FM antenna for WFMK-FM analog.
Just below the monopole is a two-bay FM antenna for WITL-HD.
In an emergency this antenna can also be switched to provide analog
backup service for any of the four FM stations.
Below that is the four-bay FM antenna for WJIM-FM analog.
Near the base of the tower is a maze of coaxial cables and ice bridges
for the cellular and land mobile systems on the tower.
WJIM-FM has both main and backup analog transmitters at the site.
To the left of the rack is the main, a Harris HT25FM.
To the right of the rack is the backup, a Harris FM25K.
In the rack are main and backup Moseley STL receivers, a temporary
Armstrong STL receiver, a Bird Wattmeter panel, and Burk remote control panels.
WITL-FM analog uses the Continental 816R1 transmitter.
The Harris HT30FM transmitter is for WFMK-FM analog.
This transmitter was installed in 2005 by contract engineer Craig Bowman.
Craig Bowman also installed the BE FM 10S solid state transmitter.
Rick points to the switching matrix that allows this transmitter to
change frequency and input audio so that it can be used as an analog
backup transmitter for any of the four Citadel FM stations in Lansing.
Each of the analog antennas is fed through a bandpass filter. Here are the
ERI bandpass cavities for WITL-FM and WFMK-FM.

manufactured by Steve Campbell at Entronics.
In the WITL HD rack, from top: Axia analog node, Harris FlexStar Exporter,
Entronics switch interface and controller, Optimod 8200 for WMMQ-FM analog
backup, Omnia 6EXi for WITL-FM analog and HD, and Harris FlexStar HD Exciter.
Harris ZX2000 transmitter for WITL-HD.
We installed a Day Sequerra HD tuner and Broadcast Tools silence monitor
so that someone would know if the HD transmitter went off the air.
We turned on WITL-HD on Saturday, September 22, 2007. Rick quickly
unpacked the Sangean HD RadioTM to hear it for himself.
