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

FM25B Professional Synthesized FM Stereo Transmitter Kit
FM Stereo Transmitter
✔ The newest Ramsey transmitter!
✔ Rock stable PLL synthesized
✔ Front panel digital control and
display of all parameters!
✔ Professional metal case
✔ Super audio quality!
You told us what you wanted, and we listened! The legacy continues with the latest Ramsey transmitter, designed from the ground up to YOUR SPECS!
The FM30 is designed around an RF tight vinyl clad
metal enclosure for noise free and interference free
operation. All settings are done 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 the 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 the
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 operation. RF output is through 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.
The FM30 operates on a 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 a perfect
match with your computer to broadcast your music files throughout your house. If
you're looking for a super performer without all the features of our FM100 series
transmitters, the new FM30 is for you! (Note: The end user is responsible for complying with all FCC rules & regulations within the US, or any regulations of their
respective governing body).

What The Customer’s Are Saying...
We really did it this time! The UP24 is one of our most advanced kits to date, and
an absolute MUST for anyone serious about the environment around us! But the
applications only begin there.
The unique design allows unprecedented super high resolution measurements
and display of absolute atmospheric air pressure. The UP24 senses ambient air
pressure and critically calculates elevation with unheard of precision! Using a
highly sensitive sensor and 24-bit A/D converter in a special noise-immune
design, less than 1/3" of an inch of elevation resolution is achieved! YES, we said
1/3 of an inch! This high accuracy and resolution opens the door to a host of
sophisticated environmental air pressure monitoring applications.
Unlike your normal run-of-the-mill barometer, air pressure is sensed in Pa's or
kPa's. What are those you may ask? Pascals or KiloPascals. However, don't be
afraid, for your convenience, and to fit any application you may have, it is also displayed in millibars, bars, PSI, atmospheres, millimeters of mercury, inches of mercury, and feet of water! Take your pick! The range of the UP24 is 15kPa to
We've talked about air pressure, now let's talk about elevation! The incredibly
precise 24 bit A/D converter in the UP24 looks at the air pressure and converts it
to elevation above sea level. In both graph and text, the elevation is displayed to
a resolution of 1/3”! Yes, I said 1/3 of an inch! The applications for the super
accurate elevation meter are endless. From watching and recording elevations
during hiking trips to measuring and recording the wave heights on boats! Let
your imagination take over from there!
What if you're in the field and you want to save data captured in your UP24? The
built-in FLASH storage provides 13,824 samples of storage. Then you can transfer
your data to your PC with a standard USB interface.
While the UP24 is small enough to be kept in your coat pocket it boasts a large
2.78" x 1.53" 128x64 pixel LCD display screen making viewing easy. Display
modes include both realtime pressure and elevation graphs as well as pressure
and elevation statistics. There are 12 user selectable sample rates from 1/10th of
a second all the way up to every 15 minutes.
Needless to say, you cannot put all the specs and screen shots in the limited
space of this ad! Visit our website at www.ramseykits.com for full specs and
If you're looking for the finest air pressure and elevation sensor, check out the
