What’s Hot for 2007!
The Newest And Neatest Goodies
✔ Monitors the entire aircraft band without tuning!
✔ Passive design, can be used on aircraft, no local
oscillator, generates and creates no interference!
✔ Great for air shows
✔ Patented circuit and design!
For decades we have been known for our novel and
creative product designs. Well, check this one out! An
aircraft receiver that receives all nearby traffic without
any tuning. It gets better... there is no local oscillator
so it doesn't produce, and can't produce, any interference associated with all other receivers with an LO.
That means you can use it onboard aircraft as a passive
device! And what will you hear? The closest and
strongest traffic, mainly, the one you're sitting in! How
unique is this? We have a patent on it, and that says it
This broadband radio monitors transmissions over
the entire aircraft band of 118-136 MHz. The way
it works is simple. Strongest man wins! The
strongest signal within the pass band of the radio will
be heard. And unlike the FM capture effect, multiple aircraft signals will be heard simultaneously with the strongest
one the loudest! And that means the aircraft closest to you,
and the towers closest to you! All without any tuning or looking up frequencies!
So, where would this come in handy?
1. At an air show! Just imagine listening to all the traffic as it happens
2. Onboard aircraft to listen to that aircraft and associated control towers
3. Private pilots to monitor ATIS and other field traffic during preflight
activities (saves Hobbs time!)
4. Commercial pilots to monitor ATIS and other field traffic as needed at
5. General aircraft monitoring enthusiasts
Wait, you can't use a radio SPECIFICATIONS

✔ ROHS soldering station!
✔ Digital multimeter!
✔ Regulated lab power supply!
✔ Everything all in one unit!
Take a close look! On your left is a multi-function 3½ digit digital multimeter. Its
large backlit LCD display can be seen from anywhere on your bench while you’re
working. The DMM also features built-in transistor, diode, and continuity testing,
data hold, and audible alarm. Next up, the regulated lab DC power supply.
Switch selectable ranges of 3V, 4.5V, 6V, 7.5V, 9V, and 12V provide a continuous
duty current of 1.5 amps with a 2 amp peak! Features both overload protection
and overload indication.
To the right we have a high quality temperature regulated soldering station. The
24V low voltage iron features an isolated ceramic 48 watt temperature controlled
element. Front panel control gives you variable tip temperature control from
150°C to 450°C and LED indication of power-on and heating-on. Runs on 120VAC.

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 resulution 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. Includes a built-in NiMh battery
pack for up to 4 days of continuous use. 110VAC charger is included. May also
be charged from a 6-12VDC source.
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
UP24, truly a marvel in the industry! Available in a ready-to-build kit or a factory
assembled and tested version.
