Where The Fun Always Starts!
Phone Patch Mixer
✔ Send telephone calls over-the-air!
✔ Stereo line/mic/phone line mixer!
✔ Automatic gain, noise gating & compression!
This is a perfect match to any of our AM or FM
broadcasters! Sure it's easy to plug a music
source into any of them, but when you want to
add a microphone (after all, you ARE the Disc
Jockey of your station!) or if you want to put incoming
phone calls on-the-air and properly mix them together, it
becomes difficult! Not anymore with the PPM3. All three audio inputs
can be easily mixed together and put onto the Line output for feeding into any of
our transmitter kits!
Simply plug your microphone, phone line, phone handset, and stereo line level
program source into the PPM3. Connect the output to your AM or FM broadcast-er's line level input and you're all set! Separate independent automatic noise gating and automatic variable gain and compression circuits are used for both the
telephone line audio and microphone inputs to assure a great sounding line output! The stereo line level mixer features mono injection of phone line and microphone audio for equal balance. Powered by 9-15VDC. Now when those people
call complaining about YOU, put THEM on-the-air!

Electronic Cricket Sensor
✔ Chirps like a real cricket!
✔ Senses temp & changes chirp accordingly!
✔ You can determine actual temp by chirps!
✔ Runs on 9VDC
Sounds just like those little black critters that
seem to come from nowhere and annoy you
with their chirp-chirp! But like the little critters,
we made it sensitive to temperature so when it gets warmer, it chirps faster!
That’s right, you can even figure out the temperature by the number of chirps it
generates! Just count the number of chirps over a 15 second interval, add 40,
and you have the temperature in degrees Fahrenheit!
Not as fancy as a digital thermometer, but not as unique either! And unlike its little black predecessor, the ECS1 operates from around 50°F to 90°F! I don’t think
there are too many real crickets chirping away at 90°F! A unique thermistor circuit
drives a few 555 IC’s providing a variable chirp that is guaranteed to annoy everyone around you! But just watch their faces when you tell them the temperature
Runs on 9-12VDC or a standard 9V battery (not included). Includes everything
shown, including the speaker and battery clip, to make your cricket project a
breeze. But don’t step on it when it starts chirping...voids the warranty!
ECS1 Electronic Cricket Sensor Kit
✔ Negative ions with a blast of fresh air!
✔ Generates 7.5kV DC negative at 400µA
✔ Steady state DC voltage, not pulsed!
This nifty kit includes a pre-made high voltage ion
generator potted for your protection, and probably
the best one available for the price. It also
includes a neat experiment called an "ion wind
generator". This generator works great for pollution removal in small areas (Imagine after
Grandpa gets done in the bathroom!), and moves
the air through the filter simply by the force of ion repulsion! Learn how modern spacecraft use ions to accelerate through space.
Includes ion power supply, 7 ion wind tubes, and mounting hardware for the ion
wind generator. Runs on 12 VDC.

Electrocardiogram Heart Monitor
✔ Visible & audible display of your heart rhythm
✔ Re-usable sensors included!
✔ Monitor output for your scope
✔ Simple & safe 9V battery operation
Enjoy learning about
the inner workings of the
heart while at the same time covering the stage-by-stage electronic
circuit theory used in the kit to monitor it. The three probe wire pick-ups
allow for easy application and experimentation without the cumbersome harness
normally associated with ECG monitors. Operates on a standard 9VDC battery.
Includes matching case for a great finished look. The ECG1 has become one of
our most popular kits with hundreds and hundreds of customers wanting to get

Check Out What”s New!
✔ 100KhZ TO 1.0GHz!
✔ Built-in power meter!
✔ Built-in frequency counter!
✔ Built-in sweep generator!
✔ Built-in calibrated RSSI meter!
✔ RS232 control
In 1986 we introduced the COM3
Communications Service Monitor which broke
the $2K price barrier for performance features in
the $10K units! The legacy continues at Ramsey with the
brand new COM3010!
It’s our full duplex service monitor designed from the ground up to give you features and performance at a price that can’t be beat! Covering a broadband spectrum of 100kHz all the way up to 1.0GHz at 0.1ppm accuracy, the COM3010
boasts a full compliment of built-in features. This includes a power meter with a
100W dummy load, SINAD meter, frequency counter, sweep generator, calibrated
RSSI meter, RS232 control and Li-Ion battery operation. Foolproof design automatically switches any RF power mistakenly keyed into the signal generator input
directly to the dummy load! No more fried front ends!
The COM3010 receives and displays both AM and FM modulation. The signal generator also provide both AM/FM modulation with internal and external sources,
and generates CTS and DPL tone squelch tones. The built-in frequency counters
measure and display RF from 100kHz to 1GHz and audio from 60Hz to 3KHz. The
entire service monitor weighs only 14 lbs for easy travel. Includes one Li-Ion battery pack to provide 1 hour of operation. Two additional battery packs may be
added to extend life to 3 hours. Visit www.ramseytest.com for details.

Digital Voice Recorder
✔ Multiple message storage & selection!
✔ Full function controls with 7 seg display!
✔ Variable output levels for any equipment!
✔ Perfect for hold messages, broadcast
announcements, and much more!
The BS2 provides up to 4 minutes of digital voice
storage. That can be broken down in a maximum of 9 separate stored messages. The message number is displayed on the 7 segment LED front panel display! Recording/playing/stopping is similar to a standard
recorder. You can start, stop/pause your message during both record and playback! Now you can have separate and distinctive messages to fit various applica-tions...or even different sponsors!
The BS2 has a built-in, highly sensitive electret condenser microphone for recording your voice messages. However, you can also plug in an external microphone
and even an external line level input for that professional studio sounding recording. External inputs also feature variable level controls to optimize your recording!
Playback-wise, the BS2 features adjustable line level outputs (two mono outputs
for stereo inputs) to properly feed any application! This is perfect for telephone
system announcements on hold (MOH source), radio broadcasters, transmitters,
and audio/visual displays. You can also directly drive a speaker with the built-in
amplified speaker output and monitor the levels with the built-in headphone jack.
Whatever your application is, the new BS2 has you covered! Runs on 12-15VDC.
