[Leigh] is a HAM operator (you may know him as wa5znu). He is familiar with a signal visualization tool called a waterfall which plots signal strength and frequency over time. He wanted to build hi… ...

For the transmitter, ... The receiver is a bit more complex, requiring a LM386 amplifier and LM393 comparator to create a clean signal for the second Arduino to read.

Long-range RC transmitter “I started using Bluetooth devices like the HC-05 modules, but I found that these sometimes randomly disconnected. Since then I’ve been using the NRF24L01 modules ...
