Where YOU become the DJ!
Digital FM Stereo
✔ Rock stable PLL synthesized
✔ Front panel digital control and
display of all parameters!
✔ Professional metal case
✔ Super audio quality!
✔ 25m W and 1W models!
For nearly a decade we’ve been the leader in hobbyist FM radio transmitters.
Now for 2005 we introduce our brand new FM30 series of FM Stereo
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 FM30 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
FM35WT version, with 1W output for our export market! Both are designed around an RF tight vinyl clad
metal enclosure for noise free and interference free
operation. All settings are done through the front
panel digital control and LCD display! All settings are
stored in non-volatile memory for future use.
Both the FM30 and FM35WT operate on 13. 8 to 16VDC and include a 15VDC
plug-in power supply. The stylish metal case measures 5. 55"W x 6.45"D x 1.5"H
and is available in either white or black. (Note: The end 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 valid APO/FPO addresses or
valid customs brokers for end delivery outside the continental US).

FM35BWT Digital FM Stereo Transmitter, Assembled, 1W, Black
Stereo FM Transmitter
✔ Fully synthesized 88-108 MHz for
no frequency drift
✔ Line level inputs and output
✔ All new design using SMT technology
Need professional quality features but can't justify the cost of a commercial FM exciter? The
FM25B is the answer!
A cut above the rest, the FM25B features a PIC microprocessor for easy frequency programming without the need for look-up tables or complicated formulas! The transmit frequency is easily set using DIP switches; no need for tuning
coils or “tweaking” to work with today's “digital” receivers. Frequency drift is a
thing of the past with PLL control making your signal rock solid all the time - just
like commercial stations. Kit comes complete with case set, whip antenna, 120
VAC power adapter, 1/8" Stereo to RCA patch cable, easy assembly instructions,
and the SMT parts are factory preassembled - you'll be on the air quick!
FM25B Professional Synthesized FM Stereo Transmitter Kit
Tunable FM Stereo
✔ Tunable throughout the FM band,
✔ Settable pre-emphasis 50 or 75 μSec
for worldwide operation
✔ Line level inputs with RCA connectors
The FM10C has plenty of power to cover your home, back
yard, or city block. You'll be amazed at the exceptional audio
quality of the FM10C. Tunes through the entire 88-108MHz band. Re-broadcast
your favorite music commercial free and with the dynamic range the musician
intended, without all that nasty compression the big boys use to make their station sound louder than the competition. Compression produces a noticeably
muddier and less dynamic sound. Runs on an internal 9VDC battery, external 5-
15VDC, or our FMAC AC power adapter.

Our Patented Design Has Now Made
The Most Popular Kit In Our History!
Passive Air Band
For decades we have been known for our novel and
creative product designs. Well, check this one out!
An aircraft receiver that receives all nearby traffic
without any tuning. It gets better... there is no local
oscillator so it doesn't produce, and can't produce,
any interference associated with all other receivers
with an LO. That means you can use it onboard aircraft as a passive device! And what will you
hear? The closest and strongest traffic, mainly,
the one you're sitting in! How unique is this? We
have a patent on it, and that says it all!
This broadband radio monitors transmissions over the
entire aircraft band of 118-136 MHz. The way it works is simple. Strongest man wins! The strongest signal within the pass band of the radio
will be heard. And unlike the FM capture effect, multiple aircraft signals will be
heard simultaneously with the strongest one the loudest! And that means the aircraft closest to you, and the towers closest to you! All without any tuning or looking up frequencies! So, where would this come in handy?
1. At an air show! Just imagine listening to all the traffic as it happens
2. Onboard aircraft to listen to that aircraft and associated control towers
3. Private pilots to monitor ATIS and other field traffic during preflight
activities (saves Hobbs time!)
4. Commercial pilots to monitor ATIS and other field traffic as needed at
5. General aircraft monitoring enthusiasts
Wait, you can't use a radio receiver onboard aircraft because they contain a local
oscillator that could generate interfering signals. We have you covered on that
one. The ABM1 has no local oscillator, it doesn't, can't, and won't generate any
RF whatsoever! That's why our patent abstract is titled "Aircraft band radio receiver which does not radiate interfering signals". It doesn't get any plainer than that!
Available as a through-hole hobby kit for easy
or a factory assembled
& tested SMT version to
operate right out of the
box! The factory assembled version has
become a favorite at air
shows across the country. Just plug in the
enclosed headbuds (or
your favorite Walkman
style headphones, and
you’re listening to all
the activity on the
ground and in the air!
Join in the excitement of monitoring your local aircraft the easy way, with our
patented tune-free receiver!
