Aircraft Band Receiver

With a frequency range of 70 MHz to 110 MHz, the FR1C has become extremely popular for receiving the standard FM broadcast band
(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
the band. Unlike most FM receivers, the FR1C includes a separate demod output (unfiltered) to drive SCA decoders including our SCA1C SCA
Decoder below. Also makes a great mate to our FM10C FM Stereo Transmitter learn the basics of both FM transmitters and receivers!
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
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
matching custom case set, measuring 5”W x 1½”H x 5¼”D.

FM Broadcast Band Receiver

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 the
wealth of programming available to those “in-the-know”! Programming available runs the gamut from stock quotes to rock music, from easy
listening to all news. These services are “hidden” in subcarriers riding along with the standard FM radio station’s usual programming. The
decoder connects to the detector output (unfiltered audio) on an FM receiver. If your receiver does not have such an output, consider our FR1C 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 standard
9VDC battery (not included). Case measures 5”W x 1½”H x 5¼”D.

SCA Subcarrier Decoder
Communicate in total privacy over your radio! This is the popular SS70C descrambler/scrambler that you’ve read about in all the
Scanner and Electronic magazines. The technology used within the unit is known as speech inversion which is compatible with
many police department systems; hook it up to your scanner speaker terminals and you’re in business. (However, always be sure to
check with your local authorities to ensure that you’re not straying into any unlawful communications reception.)
The SS70C is full duplex in operation - you can scramble and unscramble at the same time. Easily configured for any use! Easy to build since all complex circuitry is contained in a
custom ASIC chip which provides clear, clean audio. Powered by 9 to 15VDC, with 3.5mm mini phone type input/output jacks. The included case measures 5”W x 1½”H x 5¼”D.
