AM AND FM CARRIER CURRENT RECEIVERS
The AM carrier current receiver is designed to receive carrier current signals in the 200-350 kHz range from the power line that have been transmitted by a carrier current AM transmitter. The receiver has variable tuning that is adjusted internally via two trimmer capacitors. The receiver is a TRF type using an MC1350 IC as an RF amplifier feeding a diode detector and AGC system. Audio output is an LM386 IC amplifier delivering 0.5 watt of audio. The receiver has a volume control and built in coupling to the power line. Our AM88 in the AM mode may be used with this receiver to make a carrier current broadcasting, intercom, or audio monitoring & surveillance system that is difficult to detect.
The carrier current FM receiver is designed to receive carrier current signals in the 200-350 kHz range from the power line that have been transmitted by a carrier current FM transmitter. Our AM88 in the FM Mode may be used with this receiver to make a carrier current audio broadcast, intercom, audio monitoring and surveillance system that is hard to detect. The receiver consists of an RF amplifier stage with a bandpass input filter feeding a PLL FM demodulator and audio system. Audio output is an LM386 IC amplifier delivering 0.5 watt of audio. The receiver has a volume control and built in antenna coupling to the power line. FM carrier current operation is preferable in environments where power line noise may be a problem.
These receivers were described in an original magazine article which is posted on this site
