Digital FM Stereo Transmitter
Passive Air Band
✔ 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 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
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 SPECIFICATIONS

Professional features at a hobbyist price! To begin with, we designed it with the
latest technology, utilizing a rock stable synthesized PLL dual conversion receiver. We gave it
superb image and adjacent channel rejection to allow you to lock onto the signals you want and not to be
bothered by those you don’t! SPECIFICATIONS

The top request we’ve had for a professional aircraft
receiver was to embed automatic runway lighting control. Consider it done! The lighting controller follows the standard protocol for remote runway lighting. The
pilot “keys” his microphone on the local CTAF channel for the specified number of times. All you need to do is
set the receiver for the lighting control mode, then make sure the squelch is closed and will open on a suitably
strong signal. Typically the number of “keys” or “events” according to the receiver control the lighting as follows: 3 events, 25% brightness; 5 events, 50% brightness; and 7 events, 100% brightness. The AR2’s
adjustable lighting timer sets turn-on duration to your needs. Includes the matching case and knob set and
power supply. For the aviation professional that is not interested in building the receiver, the AR2 and the lighting controller are also available factory assembled and tested, ready to go. Just plug it in and you’re all set.

For nearly a decade we’ve been the leader in hobbyist FM radio transmitters. The FM30 series of
transmitters is the latest and greatest! 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
only market! Both are designed around an RF
tight vinyl clad metal enclosure for noise free and
interference free operation.
All settings can be
changed 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 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 non-volatile memory for future use!
The stylish black metal case measures 5. 55"W x
6. 45"D x 1.5"H. Runs on 13.8-16VDC, plug-
in110VAC power supply included.
