Title: WA1QIX PWM modulator board set Post by: ND8D on February 09, 2019, 05:12:52 PM I purchased a set of boards form Steve WA1QIX to build my own transmitter but I went a different direction with the modulator.
I populated the PWM modulator and overload/shutdown boards and put them in a "chassis" made of FR4 with a power supply transformer, power switch, IEC power connector, and XLR. I'll include all of that with the sale. I did test the PWM section and it does work. The PWM driver board is unassembled, but complete with all parts except the fets and diodes. For schematics see classeradio.com (https://i.imgur.com/PNxiOPp.jpg) I am asking $120 shipped OBO. Please send me an email at *mycall*@arrl.net 73's!
