Now I have this nice power amplifier running at a remote place and I am not able to read its display to gather important information like SWR, power of the selected band. And there's a unreachable button for initating the tuning cycle. :(
What did you say? Query the data from its serial port, wrap an API around it with Python Flask, order an ESP32 with an OLED, let it pull the data over the network and make a tiny, portable and wifi connected display? Maybe with a tune button?
