stereo transmitters for more than
two decades!

player, CD player, or computer, and broadcast it on any
frequency in the standard FM broadcast band.
The sound quality and stereo separation of this little
transmitter will keep the pickiest audiophile happy.
The FM25B features a PIC microprocessor for easy frequency programming through board mounted DIP
switches. The transmit frequency is Phase Locked
Loop (PLL) controlled for unparalleled stability making
frequency drift a thing of the past, extremely critical for
digital tuners. The RF output level is adjustable from
5u W to 25 m W via a potentiometer. Use the built-in
whip antenna or use an external antenna with the
standard "F" external antenna connector on the rear
panel. Just plug it in and you're on the air.
(Note: The FM25B is a do-it-yourself learning kit that you assemble.
Please remember that the end user is responsible for complying with
all FCC rules & regulations within the US, or any regulations of their

Tru-Match FM Antenna
TM100 Tru-Match FM Antenna Kit $59.95
The unique PVC waterproof design has
made the TM100 one of the most reliable
antennas available for the private broadcaster! Broadband over the entire 88-108MHz
range makes installation a breeze without
any tuning. Easy “F” connector termination.
The true professional workhorse of our FM Stereo transmitter line, the FM100B has
become the transmitter of choice for both amateurs and professionals around the world. From the
serious hobbyist to churches, drive-in theaters, colleges and schools, it continues to be the leader. Not just a
transmitter, the FM100B is a fully functional radio station and provides everything but the audio input and antenna system! Just add that and you’re on the air!
This professional synthesized transmitter is adjustable directly from the front panel with a large LED digital read-out 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 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.)

classic Nixie tube
clocks perfectly mesh
today's technology with the
Nixie era technology of the 60's. Of course,
features you'd expect with a typical clock are all supported with the Nixie clock... and a whole lot more!
The clocks are programmable for 12 or 24 hour mode,
various AM/PM indications, programmable leading
zero blanking, and include a programmable alarm with
snooze as well as date display, 4 or 6 tube, kit or
assembled!
We then jumped the technological time line of the
60's Nixie displays by adding the latest multi-colored
LEDs to the base of the Nixie tubes to provide hundreds of illumination colors to highlight the glass
tubes! The LED lighting can be programmed to any
color and brightness combination of the colors red,
green, or blue to suit your mood or environment.
Then we leaped over the technological time line by
integrating an optional GPS time base reference for
the ultimate in clock accuracy! The small optional GPS
receiver module is factory assembled and tested, and
plugs directly into the back of the clock to give your
Nixie clock accuracy you could only dream of!
The clocks are available in our signature hand rubbed
Teak & Maple, or futuristic clear acrylic bases. You also
have your choice of IN- 14 or highly sought after IN- 8-2
nixie tubes (for the 6-tube clock).
