Here we are running some initial Phasing Transmitter tests by injecting a 1100 Hertz tone into the audio unit and with a phased output from the Arduino Uno/Si5351 into my RADIG V.2 board we are looking at the output at 7.2 Megahertz.
The Microphone amplifier stage needs a pre-amp to work with some of the microphones I have. That is next on the list and then we will record what our phasing Transmitter sounds like with voice. Along the way we will look at carrier suppression and opposite sideband suppression. But the hardware is pretty simple and you can homebrew a 2Q4. So no excuses.
