Variable Amplifier Impedance:  idea of being able to vary the output impedance of a power amplifier (added 4/02)

 
Voice Scrambler/Descrambler:  This is a single-inversion voice scrambler/descrambler. Though no longer useful for police scanners, it would be a fun project for a hobbyist. It was designed for use on a 9-volt battery, but by changing resistor values proportionately, it could be adapted to use whatever voltage is available in your radio. The scramble frequency should be in the 3KHz-3.5 KHz range.  Designed by Andrew R. Morris  (added 09/05)
Voltage Controlled Panner:  (electronic schematic / circuit added 2/05)
VU Stereo Meter:  (electronic schematic / circuit added 2/05)
Weighting Filter for Audio Measurements:  (electronic Circuit added 03/06)
