This time I was spending the holidays as usual away from the city, further improving my smarthome. This time I was installing a bunch of devices with nRF24L01+ radios. When I was running out of spare nRF24L01+ modules, I noticed that I was left with a bunch of weird modules that kind of work, but really crappy. They feature huge packet losses, but whenever you touch the PCB antenna, it goes away. I decided to look into the problem and document my findings.
