#13: D-104 Microphone amplifier / Equalizer for Ham Radio

This video describes the microphone preamp and equalizer that I designed in 1999 to use with my Astatic D-104 microphone with my ham radio. The D-104 suffers from two issues when used with modern ham radios - impedance mismatch and non-ideal frequency response. The circuit addresses both of these issues. The video briefly describes the circuit, it's frequency response, and demonstrates the bass and treble adjustments using an oscilloscope and signal generator.
