In September, 2007, we were asked to help construct a new FM station
for Clear Channel Radio in the Missoula market. The new station
would share the transmitter building, tower, and antenna with existing
station KBAZ at the Mount Dean Stone Electronic Site.
Local Chief Engineer Todd Clark and David Hubbard assess the equipment
layout, starting with the new ERI combiner.
Americom Tower was contracted to take down the KBAZ antenna and replace
it with a new, combined antenna for KBAZ and KXGZ. At left, Wayne Nelson
with the load line and winch. On the right, David handles the tag line.
The first two bays of the new antenna are hoisted on the tower.
The new KXGZ transmitter is a Continental 814C, rated for 3.8 kW output.
The tall rack houses the STL relay for KLYQ-AM, the Bext exciter for the
KBAZ main transmitter, a Burk remote control, STL receivers for KBAZ,
KXGZ, and KENR, audio processing for KBAZ and KXGZ, a backup exciter and
amplifier for KBAZ, and RPU relay. The shorter rack on the right
houses wattmeters for the combiner inputs and output, audio processing for
KENR, and the KENR booster transmitter.
As David watches, Todd fires up the new transmitter into a dummy load.
David and Wayne carry one of the new antenna bays.
All eight bays of the new ERI combined antenna are mounted on the tower.
