From Dave, WA7JHZ:

The attachd JPG is my new compressor mic circuit. I designed the boards using the Copper Connection V3 software, and Gary, K7EMF, ordered the boards from PCBWay for me, as I don't have a secure Internet connection. I use it to drive my experimental 160 Watt pulse-width modulated (PWM) AM transmitter with on 3885 kHz, and it can also be used to drive a balanced 600 Ohm AF input of a broadcast transmitter.
