I've started to design some software that will control a low power linear amplifier.
I plan to use the 10W Amp from QRPLabs as the main component - I can't make one for the price they sell these kits, so thats on order.
In the meantime, I've been designing some software to control the output switching, and calculate the forward and reflected power and SWR:
Initial software design is included for the STM32 "blue pill" baord.
The software can be downloaded here.
The pinoput for the STM32 board is here.
The schematic for the RF sence using AD8307 is here.
You can purchase a STM32 board here.
The TFT display with touchscreen functionality is here:
