Passive Air Band Aircraft Monitor
✔ 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!
Written Up In Communications
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 plane you're sitting in! How unique is this? We have a patent on it, and that says it all!
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 Frequency Range: 118 MHz to 136 MHz
2. Onboard aircraft to listen to that aircraft and associated control towers Receiver Type: Patented Passive Detector
3. Private pilots to monitor ATIS and other field traffic during preflight IF Frequencies: None!
activities (saves Hobbs time!) Receiver Sensitivity: Less than 2 uV for detectable
4. Commercial pilots to monitor ATIS and other field traffic as needed at audio
their convenience Audio Output: 700m W, 8-24 ohms
5. General aircraft monitoring enthusiasts
Headphone Jack: 3.5mm stereo phone
Wait, you can't use a radio receiver onboard aircraft because they contain a local External Antenna: Headphone cord coupled
oscillator that could generate interfering signals! We have you covered on that Power Requirement: 9VDC battery
one. The ABM1 has no local oscillator, it doesn't, can't, and won't generate any RF Dimensions: 2. 25” x 2. 8” PC Board
whatsoever! That's why our patent abstract is titled "Aircraft band radio receiver 2. 5” x 4. 6” x . 9” Case
which does not radiate interfering signals". It doesn't get any plainer than that! Weight: 4 oz. with battery
Even with its compact design, we designed the ABM1 for easy construction by the electronic hobbyist. Thru-hole parts are used for all customer assembly. Several SMT
components are part of the circuit, and they are pre-installed at the factory! In addition, a factory assembled and tested SMT version with additional shielding for adjacent
channel overloading is also available for the aircraft professional that just wants to get listening quickly. Stereo earbuds are even included! If you're a private pilot, commercial pilot, airport worker, aircraft enthusiast, attend air shows, or spend a lot of time in airports or onboard aircraft, the ABM1 is for you!

Electrocardiogram Heart Monitor
✔ Visible & audible display of your heart
✔ 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. The
fully adjustable gain control on the front panel allows the user to custom tune the
differential signal picked up by the probes giving you a perfect reading every time!
Multiple “beat” indicators include a bright front panel LED that flashes with each
heart beat, an adjustable audio output to hear the beat, and of course, the monitor output to view on a scope, just like in the ER! Operates on a standard (and
safe) 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 “Heart Smart”!

Ultrasonic Radar Module
✔ Uses a 40kHz ultrasonic beam!
✔ LED alarm and distance LED’s!
✔ Buzzer and relay outputs!
✔ Adjustable range!
✔ 1A on-board relay!
✔ Factory assembled, ready to go!
A 40kHz ultrasonic beam measures the distance to oncoming objects
and warns you in several different modes. A buzzer output provides a fast, slow,
or continuous audible output. Relative distance is displayed with a 3-bar LED
graph display. An alarm indication is provided by an LED indicator as well as a set
of NO/NC relay contacts. Features adjustable alarm distance and a range of 7” to
8’. Output relay NC/NO relay contacts are rated at 1A low voltage. If you’re looking for a proximity or presence sensor for a project or application, this is the perfect choice. Just interface it into your project and you’re all set! Runs on 12VDC
at 200mA max.
