Planes Magazine said “It Puts You In The Pilot’s Seat”! Listen to the airlines, big business corporate jets, hotshot military pilots, local private<br />
pilots, control towers, and other interesting and fascinating air-band communications. You’ll hear planes miles away as well as all local traffic and<br />
control towers.<br />
The AR1C features smooth varactor tuning of the entire air band from 118 to 136 MHz. An extremely effective AGC and superheterodyne circuitry make it<br />
a super performing unit. Variable squelch mutes the receiver between conversations. Audio output jack drives any standard speaker or headphone. Includes our custom case & knob<br />

FM Broadcast Band Receiver<br />
✔ Standard FM receiver with larger tuning range<br />
of 70 to 110 MHz!<br />
✔ Ideal for FM wireless mics, SCA programming,<br />
or standard FM broadcasts<br />
✔ Demodulated audio output for driving our SCA1C decoder<br />
Perfect For<br />
“Out Of Band” Listening!<br />
With a frequency range of 70 MHz to 110 MHz, the FR1C has become extremely popular for receiving the standard FM broadcast band<br />
(88-108 MHz) as well as large portions on each side. It’s great for bug monitoring or detection and receiving SCA broadcast outside of<br />
the band. Unlike most FM receivers, the FR1C includes a separate demod output (unfiltered) to drive SCA decoders including our SCA1C SCA<br />
Decoder below.<br />
The sensitive front-end features one microvolt sensitivity with a standard 10.7 MHz IF. An FM detector IC is used along with varactor diode tuning for optimum<br />
performance. Audio output is rated at 250mW and will drive any 4-45 ohm speaker or headphone (not included). Runs on a standard 9VDC battery (not included). Includes our<br />
matching custom case set, measuring 5”W x 1½”H x 5¼”D.<br />

How Do They Get That<br />
Commercial Free Music?<br />
Believe it or not, they get it off the local FM radio station with a special decoder! Now you can build your own decoder and tap into<br />
the wealth of programming available to those “in-the-know”! Programming available runs the gamut from stock quotes to rock music, from<br />
easy listening to all news. These services are “hidden” in subcarriers riding along with the standard FM radio station’s usual programming. The<br />
decoder connects to the detector output (unfiltered audio) on an FM receiver. If your receiver does not have such an output, consider our FR1C<br />
FM Receiver above! Tune into what you’ve been missing, try the SCA1C. Includes a custom case set to match the FR1C receiver above. Runs on a<br />
standard 9VDC battery. Case measures 5”W x 1½”H x 5¼”D.<br />

KIT SCA Subcarrier Decoder<br />
Communicate in total privacy over your radio! This is the popular SS70C descrambler/scrambler that you’ve read about in all the<br />
Scanner and Electronic magazines. The technology used within the unit is known as speech inversion which is compatible with<br />
many police department systems; hook it up to your scanner speaker terminals and you’re in business. (However, always be sure to<br />
check with your local authorities to ensure that you’re not straying into any unlawful communications reception.)<br />
