Arduino AM transmitter
Very interesting
https://create.arduino.cc/projecthub...smitter-d3b6e3 Has anyone made this? It looks cheap and easy to build and according to the video it works reasonably well, if you ignore the harmonics. I may give it a go. Gabriel |

Re: Arduino AM transmitter
Nice, the article said something about an LPF (Low Pass Filter) on the RF output. These modern, cheap micros are amazing to people thinking* anything above a few kHz is RF, it isn't anymore!
*Like me a while ago, doing maths at 50MHz is very cheap today. |
