Ahh!!... the conveniences of today's technology in our modern world! Voice recognition, LED's instead of incandescent bulbs, on-board com-
puters, on-board hard drives, automatic parallel parking, automatic radar cruise control, and of course, wireless remote controls! They make it so
simple, just have the "key" (called a key fob) somewhere in your pocket or purse, get near the vehicle, it knows that you are there! Touch the door han-
dle and the vehicle unlocks. Get in and touch the start button and the vehicle starts. You have yet to use a key through the whole process! And don't forget
all the wireless controls for your house lights, building access and entertainment systems. They're so great… until they don't work!
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 car! 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 malfunc-
tioning sensors, antennas, or other system components in the vehicle. The WCT3 is designed for both the car dealer service shops as well as the consumer. Until now there was no
way to determine where the system was failing. Please note that the WCT3 simply verifies the generation of the control signals. Indication of signal presence is not an indication the
encoded data is valid, nor is it a reader of that code, so don’t worry, this will not help anyone steal your car!
First, let's cover a few basics about vehicular keyless entry. In general, (not all systems are created equal), the vehicle itself generates a signal at 125 kHz or 20kHz. This is the signal
that is used to "talk" to your individual key fob. Upon receiving the signal, your key fob "returns" a 315MHz signal uniquely encoded with an identification code and unlock com-
mand. If the embedded codes of the vehicle and your key fob match, you're in! Once you have "unlocked" the vehicle, and are inside the vehicle, the presence of your key fob is
detected in the same way when the "start" button is pressed. If the codes match, the vehicle can be started. Some manufacturers also use Infrared (IR) signals in their key fobs to
add additional user control functions to the vehicle. In that case, the key fob generates a modulated IR signal that is received by the vehicle's IR detectors placed throughout the
perimeter of the vehicle.
Testing your system is easy. To test the complete key fob-to-vehicle and vehicle-to-key fob 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 pres-
ence 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! But the WCT3's uses go beyond the automotive world. The majority of building wireless access systems also utilize 125 kHz. Just hold the test set near the
building access sensor and the WCT3 will detect the 125 kHz signal. That will help you troubleshoot door access locations that are not working. It gets even better... you can use the
WCT3 to test virtually any other 315 MHz, 433 MHz, 125kHz, 20kHz and IR wireless control system to verify generation of a signal. We should rename this "the handy-dandy, univer-
sal vehicle entry and wireless remote control tester"!
The WCT3 test set is housed in a compact 2.25" x 4.6" x 9" case and is powered by a standard 9VDC battery (not included). The test set is available as a do-it-yourself hobby kit or
factory assembled and tested. For the kit builder, the WCT3 contains both SMT and through-hole components, with 170 solder points. If you're a car dealer, independent service
shop, or simply an owner of a newer vehicle with keyless entry, or have wireless entertainment controls you can't afford not to have a WCT3!
(Our next kit should be a sensor and a
voice alarm that says “hey dummy, just because your car is still running, you still have to give the key fob in your pocket to the valet parking dude”!)

So you're outdoors on that remote Caribbean island that has the small table and two beer bottles with limes sitting on it. The first
thing that happens is that your cell phone (that remarkably had service!) goes dead. Next problem, you're sitting there, reading your
latest book on your tablet and it goes dead. You look around and there's no electrical outlets for your chargers. Of course there's not,
you're on a deserted island with a friend, a table, two beers, and two limes! What DO you do?
This neat "briefcase" opens up and becomes a self-standing solar generator! Just set it up, plug your device's vehicle charger into the DC
accessory connector (same as a vehicle accessory power jack) and you're in like Flint! The output of the solar briefcase is connected to a 10'
cable to give you plenty of space to set it up outside and cable it inside (the tent on that island!) to run your devices.
The two powerful solar panels generate 13 watts of power, that's 14VDC at a working current of 750mA! That's plenty of power to run or charge any of your DC chargers or devices,
from your cell phone to your laptop… and a whole lot more. The solar briefcase also includes a male vehicle power plug and a set of battery clamps to charge your vehicle right
from a jack or directly to the battery. The briefcase measures 20.1" x 14.7" x 1.6" and weighs a scant 9.7 lbs.
(I’m taking one of these when I move to Fiji with Truman!)

We’ve all been there; your car sat in a parking lot for a week or so, you came back and the battery was flatter than a pancake!
It doesn’t take much to drain a battery down if the vehicle is not run, and today’s vehicles have electronics draining the battery
24/7 whether the car is on or off!
Now you can rest assured you will never have a dead battery! Just keep this handy solar trickle charger plugged into your
accessory power jack (cigarette lighter plug for those of you that don’t know the new name!) and you are all set. Built-in protection pre-
vents current reversal. Provides 14.5VDC at 125mA. Comes complete with cigarette lighter plug, battery clamps, and window suction cup
mounts. If your car sees the sun, your car’s battery will never be dead! Measures 13.4” x 4.7” x 0.6”, perfect for a sun visor, just flip it down when you
(I keep one of these in the "seasonal vehicle" that just sits because I'm too busy writing ad copy for catalogs! The one time I drove it this year, it started right up! Editor…)
Works with any vehicle!
Easy window or visor mounting!
