Title: New Compressor Mic Circuit by WA7JHZ Post by: Steve - K4HX on October 14, 2018, 11:58:32 AM From Dave, WA7JHZ: AMfone - Dedicated to Amplitude Modulation on the Amateur Radio Bands
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. |
