Vintage Battery Eliminator
Collectors come across some great
deals on antique battery-powered
radios, but how to power them is a
real problem. Many classic radios
operated on batteries only, and in
many cases a series of three batteries
for each radio were required!
The new ABCE1 Battery Eliminator gives you an easy
way to replace all these batteries with a simple household AC power connection to resurrect your vintage
antique radios! Provides “A” filiment, “B”
plate, and “C” control grid supplies,
which are all isolated from
each other. Complete with
aluminum case. Runs on

Four-Mode Keyless 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 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 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.
