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).

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.

✔ DDS and SMT technology!
✔ Frequency range 0 Hz to 5
MHz with 0.1Hz resolution!
✔ 0 to 10V peak to peak output
✔ Sine, Square, or Triangle
✔ Non-volatile memory DC to 5 MHz...In 0.1 Hz Steps!
✔ Factory assembled and tested
Following in the footsteps of our world famous SG550, we are proud to introduce
the SG560, the next generation signal generator!
To begin with we increased the frequency range all the way up to 5MHz and all
the way down to 0Hz (yes, we mean zero...or DC!) in continuous 0.1Hz steps
across the entire range! Then we gave it a variable output level all the way up to
10V peak to peak in either Sine, Square, or Triangle waveforms! You can also provide a DC offset to the output to recreate TTL, 4000 series logic levels, low voltage
logic levels, AC waveforms with a DC component, or just plain AC signals!
The SG560 contains a 10 bit DDS and filtering for a low noise, accurate low distortion output. The output stage utilizes the latest technology in digital modems
and high power, high bandwidth DSL modems and is capable of a direct output
of 2.5W! You can even generate carrier signals in the AM band for testing AM
receivers and circuits. A jumper option for zero ohm output impedance allows for
true output terminal metering. But watch out, 2.5 watts is enough to damage
incorrectly connected circuits!
Surface mount technology is used throughout the SG560 making it extremely reliable and accurate. Frequency is entered directly on the sealed membrane keyboard and adjusted with a precision rotary encoder with an oversized knob. Both
frequency and output level are displayed on a high contrast, two-line LCD display.
The SG560 operates on 8 to 16VDC and includes a standard 110VAC power
adapter. Because of the surface mount design the SG560 is only available factory
wired and tested. If you are looking for a lab quality signal generator at a super
price, the new generation SG560 fits the bill... and a whole lot more!
