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. (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 valid APO/FPO addresses or valid customs brokers for end delivery outside the

Synthesized FM Stereo
The FM25 has been the hobbyist’s standard for FM synthesized
stereo transmitters for more than
two decades! Just plug in the
stereo left/right audio from your
MP3 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
The transmit frequency is PLL controlled for unparalleled stability making frequency drift a thing of the
past. The RF output level is adjustable from 5u W to
25 m W. Includes power supply & stereo cable.
(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 respective governing body in regards to
the application and use of the FM25B.)

Customers have complained about
“dirty” imported FM broadcasters
and exciters, so we developed this low pass filter
based on our PX50 broadcast xmtr. Really cleans up
your output, and connects easily between your transmitter & antenna. Maximum input power is 50 watts.
FMLP1 FM Low Pass Filter Kit $25.95
FM Low Pass Filter
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 readout 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
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 below for digital storage and playback of short announcements and ID’s! In addition to the line level inputs,
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.
