provides your choice of an active low or high closure!
It’s that simple! Runs on 12VDC at 60mA.
Digital Voice Changer
MK171 Digital Voice Changer Kit $14.95
This voice changer kit is a riot!
Just like the expensive units you
hear the DJ’s use, it changes your voice
with a multitude of effects! Features a
built-in microphone and both a speaker and line output. Runs on a standard 9V battery, not included.
This professional synthesized transmitter is adjustable directly from the front panel with a large LED
digital readout of the operating frequency. Just enter the setup mode and set your frequency. Once selected
and locked you are assured of a rock stable carrier with zero drift. The power output is continuously adjustable
throughout the power range of the model selected. In addition, a new layer of anti-static protection for the final
RF amplifier stage and audio inputs has been added to protect you from sudden static and power surges.
Audio quality is equally impressive. A precision active low-pass brick wall audio filter and peak level limiters give
your signal maximum "punch" while preventing overmodulation. Two sets of rear panel stereo line level inputs
are provided with front panel level control for both. Standard unbalanced “RCA” line inputs are used to make it
simple to connect to the audio output of your computer, MP3 player, DVD player, cassette deck or any other
consumer audio source. Get even more creative and use our K8094 below for digital storage and playback of
short announcements and ID’s! In addition to the line level inputs, there is a separate front panel microphone
input. All three inputs have independent level controls eliminating the need for a separate audio mixer! Just
pot-up the source control when ready, and cross fade to the 2nd line input or mic! It’s that simple! In addition
to the dual stereo line inputs, a stereo monitor output is provided. This is perfect to drive
studio monitors or local in-house PA systems.
The FM100B series includes an attractive metal case, whip antenna and
built in 110/220VAC power supply. A BNC connector is also provided for
an external antenna. Check out our Tru-Match FM antenna kit, for the
perfect mate to the FM100B transmitter.
We also offer a high power kit as well as an export-only assembled version that provides a variable RF output power up to 1 watt. The 1 watt
unit must utilize an external antenna properly matched to the operating
frequency to maintain a proper VSWR to protect the transmitter.
(Note: The FM100B and FM100BEX are do-it-yourself learning kits that you assemble. The end user is responsible for
complying with all FCC rules & regulations within the US or any regulations of their respective governing body. The
FM100BWT is for export use and can only be shipped to locations outside the continental US, valid APO/FPO addresses
or valid customs brokers for documented end delivery outside the continental US).

Entry Test Set
Just like the days of "plugs,
points, and condenser" are
over, so are the days of having
the hardware store grind
out a spare key for your
Now when your keyless
access system doesn't work,
you need to accurately detect what part of the system
is malfunctioning. This could be anything from a dead
battery in the key fob, a "brain-dead" key fob, to malfunctioning sensors, antennas, or other system components in the vehicle. Until now there was no way to
determine where the system was failing.
Testing your system is easy. To test the complete 125
kHz/315 MHz communications path just stand close to
the vehicle with the WCT3 and your key fob in hand.
Press the test button and the WCT3 will detect and
display the presence of the vehicle's 125kHz/20KHz
signal and, if they "handshake", will also detect and
display the presence of your key fob's 315MHz return
signal. You can independently test key fob only signals (panic, lock, trunk, etc.) by holding the key fob
near the WCT3, pressing the test button, and pushing
the function button on the key fob.
The same functionality testing can be done with IR key
fobs. The modulated IR signal is detected and will
illuminate the IR test LED on the test set.
If you know a few "secrets" you can also see if the tire
pressure sensors/transmitters are generating signals or
the built-in garage door opener in your rear view mirror is transmitting a signal! Runs on a standard 9V
battery. Also available factory assembled & tested.
