✔ 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 the non-volatile memory for future use.
Both the FM30 and FM35W T 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).

Our FM100B is the updated version of a truly professional frequency synthesized radio transmitter station in one durable, handsome
cabinet. It is used all over the world by serious hobbyists as well as churches, drive-in theaters, and schools. No one else offers all of these features at this price! The
included frequency display and audio level meters assist in easy operation. The "B"
version now includes some additional functionality including a line level monitor
output, improved stereo separation, spectral purity, audio clarity, and adjustable RF
Output. An exclusive selectable microphone mixer and auto AGC circuit combines
your local mic audio with your music input or mutes the music when mic audio is
present. You don’t even need an external mixer!
Sound quality is impressive; it rivals commercial stations. Low pass input filtering
plus peak limiters put maximum "punch" in your audio, and prevent overmodula-tion distortion. No wonder everyone finds the FM100B to be the answer to their
transmitting needs... you will too! The kit includes a sharp looking metal cabinet,
whip antenna, and built-in 110/220 volt AC power supply. An external antenna connection allows hook-up to high performance antennas like our TM100 and FMA200.
We also offer a high power export version of the FM100B that's fully assembled with
one watt of RF power for miles of program coverage. Many islands and villages use
it as their local radio station! The export version can only be shipped outside the
USA, or within the US if accompanied by a signed statement that the unit will be
exported. (Note: The end user is responsible for complying with all FCC rules & regulations within the US, or any regulations of their respective governing body).

Professional Synthesized
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, and easy assembly instructions, and the
SMT parts are factory preassembled - you'll be on the air in just an evening!
