COOKEVILLE, TENN.—Loads of Tv set towers are living on the tops of mountains. In that regard, there is practically nothing special about the location of WCTE’s 800-foot broadcast tower outdoors Monterey, Tenn., about ten mile push from the PBS station’s Cookeville studio more than mostly great roadways. But when our engineers have been acquiring to fall everything and deal with troubles approximately each day—sometimes far more than once—it seemed far too remote.
The journeys have been donning us out physically and fiscally. In addition, we have been expending a fortune on amplifiers and the ones we necessary have been finding hard to appear by. The electric power provides inside the amps have been proprietary and couldn’t be repaired.
We necessary a thing far more reputable so very last year we took shipping and delivery of a new Hitachi-Comark Parallax transmitter. In a week, the site crew from Comark experienced set up the one-cabinet, full with a new heat exchanger.
MODULAR Electric power Provides
With the new transmitter set up, we’re not driving to the transmitter each day, and procedure expenses are about 50 percent as much as our outdated transmitter. Our 1st electric powered monthly bill was basically 50 percent what we’d been expending, resulting in discounts of at least $2,000 a month. It was that power discounts that authorized us to replace our outdated transmitter, however other aspects have been just as essential. A person of the major-marketing factors was the reality that Parallax amps have modular electric power provides that can be obtained on eBay for about five p.c of what we’d been spending each time we lost a electric power source in an amp.
Due to the fact WCTE’s tower facility is positioned at the finish of a highway that operates several miles by means of mountainous woods, electric power failures are popular. The unexpected emergency generator always kicks in and there are plans to obtain and set up a UPS to carry the entire plant by means of the instant of failure ahead of electric power is restored, but the ease with which Parallax recovers from a dip has been beneficial.
The transmitter powers again up in just seconds and the net server lets us complete manage and checking from any where. We get e-mails from the Parallax right away when there is an issue—in nine months there has not been anything at all but electric power firm problems—but we can see voltages on every single leg, h2o temperature and flow, error logs… everything you could inquire for.
NEW COOLING Technique
Following the Parallax was set up, the site’s outdated transmitter became the backup, and aside from a new 3-period electric power circuit for the Parallax, the installation of the new cooling process was the only modification necessary in the transmitter creating. The new cooling process utilizes an indoor tank, further limiting publicity to ice-tumble from the tower. The use of flexible hoses authorized for hassle-free placement of both of those the tank and the out of doors heat exchanger.
Even the effectiveness of the cooling process is stunning. The heat exchanger did not run much at all for the duration of the tumble and winter season so I’ll be intrigued to see how it does in the summer time, with the indoor tank and the lessened heat load. It’s gotten up to about 85 degrees outdoors already this spring, and our air conditioners don’t seem to be acquiring any hassle maintaining it interesting indoors.
The Parallax has reworked how we perform. WCTE only has two engineers, and we have been scrambling to shift our learn manage, keep and run a creation truck and two IT networks and offer complex leadership for the station. When you consider into account the expense discounts on power and on our time, it truly has made a big change.
