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.

Digital Controlled FM Stereo Transmitters
FM30B Digital FM Stereo Transmitter Kit, 0-25m W, Black $169.95
FM35BWT Digital FM Stereo Transmitter, Assembled, 0-1W, Black (Export ONLY) $259.95
For more than a decade we’ve been the leader in hobbyist FM radio transmitters.
We told our engineers we wanted a new technology transmitter that would provide FM100 series quality without the advanced mixer features. They took it as a
challenge and designed not one, but TWO transmitters!
The FM30B is designed using through-hole technology and components and is
available only as a do-it-yourself kit with a 25m W output very similar to our FM25
series. Then the engineers redesigned their brand-new design using surface
mount technology (SMT) for a very special factory assembled and tested FM35BWT
version with 1W output for our export only market!
All settings can be changed without taking the cover off! Enter the setup mode
from the front panel and step through the menu to make all of your adjustments.
A two line LCD display shows you all the settings! In addition to the LCD display, a front panel LED indicates PLL
lock so you know you are transmitting.
Besides frequency selection, front panel control and display gives you 256 steps of audio volume (left and right
combined) as well as RF output power. A separate balance setting compensates for left/right differences in audio
level. In addition to settings, the LCD display shows you “Quality of Signal” to help you set your levels for optimum sound quality. And of course, all settings are stored in non-volatile memory for future use! Both the FM30B
and FM35BWT operate on 13. 8 to 16VDC and include a 15VDC plug-in power supply. The stylish black metal case
measures 5. 55"W x 6. 45"D x 1.5"H.

while also saving big bucks!
(Note: After assembly of this do-it-yourself hobby kit, the user is responsible for complying with all FCC rules & regulations within the US, or any
regulations of their respective governing body. FM35BWT is for export use and can only be shipped to locations outside the continental US or
