Not that there's anything wrong with
commercial country music...
Recently,
a new commercial station signed on the air in Victoria, B.C. at 91.3
FM÷the very same frequency that KBCS uses here in the United States.
Sadly, we're finding that the Canadian signal is blocking out
reception of KBCS for some folks in places like Pt. Townsend, Sequim,
Granite Falls and even (sigh) some spots in Seattle. The Canadian
station is legal, so we can't do anything about their broadcast
signal, but if you've lost KBCS on your radio, here are some things
you can do to try to get us back:1) Call your local cable company÷whether you're a current subscriber or
not÷and encourage them to add KBCS to their cable radio line-up.
Explain how this is a great opportunity for them to do a real
community service. Put it in writing, if you have time, and send KBCS
a copy of the letter.
2) Try tuning in to KBCS on the web! Just click the Listen to KBCS
live! button on the home page.
3) Write to the manager of the Canadian station to let them know how you
feel:
Dan McCallister, General Manager
The New X 91 Three dot fm
Top Floor, 2750 Quadra Street
Victoria, BC Canada V8T 4E8
Or go to the station's website, navigate to their staff listing and send the general manager an e-mail message.
4) Try moving your antenna to a new spot÷pointing away from Canada and
towards Bellevue. You might also try adding a directional antenna to
your system. Our engineer has some suggestions on how to do that using
low cost (Radio Shack-type) equipment:
Omni-directional
antennas receive in all directions equally. Since you are trying to
improve reception in one direction while ignoring signals to the side
or back, you need a directional antenna, such as the Radio Shack
42-2385 ($2.99), which is a simple di-pole antenna. The directional
pattern for this type of antenna is a figure-8÷meaning that it
receives as well from the front broadside as well as the back.
If
you face one side of the di-pole towards Bellevue and the other side
faces Victoria, there will be no relief. But if one tip of the antenna
points to Victoria and the broadside faces Bellevue (with the other
tip pointing south, away from Canada) you might get some relief.
This
would also apply to those of you who use rabbit ears for reception.
Radio
Shack also has an amplified table-type antenna, model 15-1833 ($29.99)
that is basically a di-pole with a figure-8 pattern. But since it is a
di-pole and lacks the front-to-back rejection, it has the added
benefit of amplification and a small profile.
Radio
Shack 15-2163 ($19.99) is a directional antenna with good rejection
from the back as well as the sides on the antenna. This antenna is
large and meant to be mounted outdoors on a mast. One end has elements
(the rods that fold out) that are longer than the elements at the
other end. The long elements are the back, the short elements are the
front and should be pointed towards Bellevue. With this type of
antenna you need a feed cable between the antenna and the radio. Use
co-axial cable (co-ax) since it is insulated and will reject any
signals leaking into the cable. Make sure you use a Balun matching
transformer to convert the co-ax connector to leads to connect to the
antenna.
Items you'll need from Radio
Shack to set up a directional antenna system
-
15-2163
$19.99 directional antenna
-
15-1143 $3.99 Balun transformer for outdoor mounting
-
$9.99 co-ax cable 50 feet.
or
Some stereos accept 75 ohm inputs so this item may not be needed for
some installations.
Mast
mounting hardware is available at Radio Shack from $6.99 to $19.99.
Sometimes you can attach the mast to a fence or pole.
I
have even seen outdoor antenna mounted in large attics. As long as
there is no foil-back insulation in the path of the antenna some
attics do work. However, nothing is better than the antenna mounted
out in free air on the roof.
Another
thing to consider is an outdoor television antenna pointed towards
Seattle. This may help since a typical outdoor antenna is directional.
If it has the big elements in back and small ones in the front it is a
directional antenna. Bellevue is in the same path as Seattle so little
or no alignment may be needed for better reception.
