http://rf-circuit-schematic.blogspot...r-mc13028.htmlhttp://www.aspisys.com/dqam.htmThis electronic circuit is AM stereo decoder that accepts the signal from the IF of a receiver (450 or 455 KHz) and decodes stereo medium wave broadcasts.
It operates at 8-15VDC and provides standard level left and right audio output for direct connection to the audio amplifier.
It may be used to support 30Hz-15KHz audio but it depends on the bandwidth of the receiver's IF.

http://rf-circuit-schematic.blogspot...#ixzz5g2Skh9Xdhttp://meduci.com/Rich Modafferi built his "connect to any radio" AM stereo decoder enclosure to house his meduci AM_ST decoder board, which complements his tube-based AM stereo C-QuAM transmitter. Rich also used his Sencore SG80 stereo generator for testing purposes. His enclosure has inputs for 455 kHz I.F and a level control is provided for adjusting this I.F input. There are both BNC and RCA I.F input jacks, and fixed and variable audio level outputs. Single indicator lamp functions for "power" and "stereo", glowing dim on power, and full bright for AM C-QuAM stereo lock.
