I've been testing my (nRF24L01 PA 2db antenna) modules and I found a strange problem, while doing
some tests I plugged my nRF's as Transmitter / Receiver, testing them just in one direction and worked fine after that for some reasons I changed the positions of the modules and found out that one of my modules can't transmit data, the strange part was that if touch the antenna the nRF starts
transmitting, If I don't touch it the it doesn't transmit.
My modules got +/- 3.3μF capacitors directing on the module.
Does anyone had such problem ?
Is that a proper antenna plugged into the module? Sounds like a loose connection on the
antenna (which greatly affects transmit power, usually makes less difference on receive.)
Make sure plug and socket are clean and tightly screwed on.

I've been testing the same module as Receiver working pretty good but not sure why when I change the receiver as transmitter it stops transmitting and the strange is when I touch the antenna or close up my hand to the antenna it starts transmitting.
I use a prototype board exactly for nRF's been testing with it the small nRF's with the on board antenna many times and the circuit and connections work well. I don't have a problem to use it as receiver but if I'd like to use it as transceiver there gonna be that problem of receiveing but not transmitting.
About the loose connection of the antenna I changed antennas as well and had the same problem.
Still got this problem and not sure what is that, anyone got any idea?
This exactly nRF from the video I'm touching it can receive perfectly but as you can see from the video if I use it as transmitter it can't transmit unless im touching the antenna. Video: nRF24L01 2db PA Problem
sry for the crappy video, low quality cam on my phone
