THE LEGACY CONTINUES!
For more than a decade we have been the leader in hobbyist FM radio transmitters. First we came out
with our low cost FM10, the tunable FM transmitter that has set records as the most popular school,
scouting, and first time hobbyist kit.
Then we introduced the world famous FM25 series of FM transmitters. We took the basic concept of the tunable
FM10, made it synthesized for rock solid and stable operation, and gave it the features and performance that made it THE LEADER in low cost FM
stereo transmitters. From there we introduced our FM100 series Super Pro FM Stereo Radio Station which became the “gold standard” for professional installations around the
NOW THE BEST OF BOTH WORLDS!
How could we make history better? First, we listened to thousands of our customers who loved the stability of the PLL synthesized FM25 series but wanted easy to change front
panel control of the operating frequency and wanted to know what frequency they were transmitting on. They also wanted the capability of controlling the audio levels at the trans-
mitter rather than changing the input levels.
We thought those were very legitimate requests, and our response was to
recommend they use the FM100 series. “But I don't need an audio mixer,
I don't need all that fancy stuff built-in, I just need a small transmitter I can
afford!” Well here you go, designed from the ground up... the FM30 series!
Our RF engineers 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 25mW out-
put very similar to our FM25 series.
Then they re-engineered their brand-new design using surface mount tech-
nology (SMT) for a very special factory assembled and tested FM35BWT
version, with 1W output specifically and solely for our export market! Both
are designed around an RF tight vinyl clad metal enclosure for noise and
interference free operation.
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 selec-
tion, 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!
The design includes EMI filters on line level audio and power inputs and a state of the art microstrip PCB inductor to reduce microphonics for the ultimate in alignment free opera-
tion. RF output is brought out to a professional, well shielded rear panel BNC connector for a perfect antenna match. Standard RCA connectors are used for left
and right line level audio inputs. 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. If you're looking for a super performer but don’t need the extra features of our FM100B series
transmitters, the FM30B is for you!
(Note: The FM30B is a do-it-yourself learning kit 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. 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 documented end delivery outside the continental US).
