Crawford Installs Two New Nautel Rigs
Broadcasting provided details of two transmitter installations.
Amanda Alexander is shown with the new NX50 in Denver, one of two new transmitters in service for Crawford Broadcasting.
WYCA(FM) in Chicago
has a new Nautel 2.5 kW VS2.5. “This
is one of the new BYOR (‘Bring Your Own Rack’) transmitters that Nautel is
offering these days,” CBC Chicago CE Art Reis wrote in a recent engineering
newsletter article. “It has an integral digital exciter, HD exgine, IP audio
I/O and USB backup audio automation. Provided we keep the internal library up
to date, should we lose the STL to that site, the transmitter can continue to
play the hits all by itself.”
He said the aux
transmitter is a 1960s vintage Gates FM-5 that functions but for which Crawford
can no longer get parts. “That old beast is coming out of service and going to
the scrap yard,” with a new Middle Atlantic rack going in to house the new
transmitter. “That arrangement will provide us with a brand-new main
transmitter and a full-power digital aux system (Nautel FM-4 and BE FMi73

involved removing 7/8-inch transmission line from the ND2.5, enlarging the hole
in a phasor to accommodate a 3-1/8-inch EIA flange and moving the current main
transmitter output to the aux port in the phasor. The engineers also reworked
and added remote control wiring. The new transmitter features a remotely
accessible GUI user interface, connected via IP to the studio network.
Engineering Cris Alexander said Crawford is employing MDCL on the new transmitter to take advantage of the “considerable
power savings that offers.”
Alexander (who also
is a contributor to Radio World) recalls putting in the previous KLTT transmitter
17 years ago. “I clearly remember unloading that thing off the truck, uncrating
and installing it — and the tower crew lived in the empty crate during the rest
of the project!”
