Radio
has been around since the early 1900's to the public. It
allows us to keep up to date with what is happening
locally or far away. We hear music, talk of all types
and it keeps us up to date with everything from
information to emergency situations that could affect
us. Radio allows you to hear different points of
interest regarding any topic near or far. The great
thing about radio is it is free to listen.
Here you will find types of radios, antennas
needed or other types of receiving.

information.
Tired of missing
your favorite radio talk show? Try
using a device to record the show. There are
several items out there that can record and play back at
another time. Tape players, such as the VersaCorder by C. Crane, will record
onto cassette tapes and allow setting timers while you
are sleeping or away. Another great device to use would
be the CC Witness by C. Crane. This
digital recording device can do so much for such a small
unit and it includes AM and FM radio. Please visit the
following page for more information http://www.ccwitness.com.
Is
your reception affected by radio noise? If you
hear humming or buzzing sounds while listening to the AM
band, it could be coming from electrical interference.
Please review the following for devices that can affect
your AM reception.
Radio noise and other annoying buzzes are many
times transmitted through an AM radio. Here is a
check-off list of the most likely causes:
Dimmer switch Neighbors dimmer switch Fluorescent light Computer Touch lamp (even when
turned off) Automatic on/off night
lights. Automatic outdoor yard
lights Electronic bug and pest
controllers Light bulb that is about to burn
out Faulty electrical switch Nearby
television set Neighbor using
fluorescent lights Christmas tree lights
& other blinking bulbs Neighbors dimmer switch (apt.
complex) Scanners Cell phone
chargers Dirty insulators on nearby power
pole Electric blanket 120V AC
smoke detectors (battery operated OK) Ionic
Breeze or other electrostatic air purifier
Ultrasonic motion
detectors Appliances with motors Wireless Signals (Wifi
routers) Note: Sometimes pool
chlorine generates electrolytic action which
causes radio noise over a wide spectrum of over
500' from the device. Unfortunately there is no
known cure.
The best way to eliminate radio noise and
interference is at its source. Here is a check-off
list of possible solutions:
The most obvious solution is to turn off the
offending device.
Temporarily switch the radio from AC power
to battery power to see if the interference was
coming from the electrical outlet (60 cycle). If
the noise stops, our Single Outlet Surge
Protector can dramatically reduce the
radio the noise. It is only for one AC power
adapter. Not to be used with power
strips.
Turn off all circuit breakers to see if the
noise stops. If it does then you know it is
something in your house. Turn off one circuit at
a time to isolate where it is coming
from.
Use a battery operated radio as a direction
finder. Turn the radio until the loudest noise
is heard. The front and back of the radio will
usually point to the noise origin.
Carry a radio around the neighborhood. Ask
other neighbors if they have problems (with
radio noise).
If a power pole is suspected, call the
utility company and they will usually check the
area and wash the insulators.
Often grounding a radio will reduce a hum
caused from AC line noise. Unfortunately most
receivers do not have a ground
connection.
Station Reception
Poor
If the reception to your favorite
station is not coming in during the day but real strong
at night, it could be a result of the station
broadcasting at a low power or transmitting in a
different direction away from your location. To find out
station information, visit Radio-Locator.com. A antenna may
help but if you are outside of the Fringe area, an
antenna may not help.
Did you know?
Q. What is the proper length for a good AM wire
antenna?
A: The optimum antenna length can be calculated by
dividing the desired AM station frequency (example 810
kHz) into the number 1005, and multiplying by 1000 to
determine the full wavelength 1005 divided by 810kHz =
1.240 x 1000 = 1,240 feet (full wave)
This means the best antenna length for 810 AM would
be 1,240 feet long because this is the actual full
wavelength of the transmission.
AM antennas can also be very effective when they are
made to capture the half wave (1/2) or quarter wave
(1/4). This is good information because not everybody
has room for a 1,240 foot long antenna. 1,240 feet
(full wave) divided by 2 = 620 feet (1/2 wave) 1,240
feet (full wave) divided by 4 = 310 feet (1/4 wave)
