INTERFERENCE PROBLEMS
Interference Frequencies
The S Sport2 radar transmits in the range of 24.15 GHz (24,150,000,000 Hz), using a
new K-band ACI design. The receiver is designed to read the Doppler frequency (the change in
frequency) in the range of 360 - 18,000 Hz. There are very few devices other than another radar
gun that could cause interference in a radar gun’s transmission frequency range. However, there
are a number of devices that could interfere with a radar gun in the receiver’s frequency range.
What Does Interference Do?
Interference can cause a radar gun to read random readings, or make it harder for the radar gun
to “see” the intended target.
Random readings are an obvious sign that there is interference. However, a loss of sensitivity can
be subtle. A common situation occurs when a large number of professional baseball scouts
operate many radar guns in close proximity.
A loss of sensitivity can cause the radar gun to be unable to “see” far enough away to get the ball
speed right when it leaves the pitchers hand. Then, as the ball gets closer to the plate, the radar
is able to get a reading, but only after the ball has slowed down. The result: the peak speed
registers lower than it actually is.
Sources of Interference
There are two main sources that can cause ghost (random) readings in radar guns: electrical
devices and objects that move or vibrate.
Electrical sources include television monitors, fluorescent lights, cellular phones, computers,
some radio transmitters, and power transformers. Moving or vibrating objects include
ventilation fans, motors, and blowing debris that can produce a nearly constant speed reading.
How to Eliminate Interference
If you are experiencing erroneous readings, try these solutions:
1. Change your position to change where the gun is aimed.
2.
Lower the sensitivity by changing the Range on the Operator Menu to 1 (low setting).
3.
Change the Option Menu Low Speed setting to a setting with a higher low speed cutoff if
the readings are at low speeds (often interference from nearby motors).
the readings are at low speeds (often interference from nearby motors).
