Super-Pro FM Stereo Radio Station Kit
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. (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 continental US.)
; PLL synthesized for drift free operation
; Front panel digital control and display of all settings and parameters!
; Professional metal case for noise-free operation
; EMI filtering on audio and power inputs
; Super audio quality, rivals commercial broadcasts
; Available in domestic kit or factory assembled
FM100B Super-Pro FM Stereo Radio Station Kit, 5u W to 25m W Output $239.95
FM100BEX Super-Pro FM Stereo Radio Station Kit, 5u W to 1W Output $299.95
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
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 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 below 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.)
