I've built a project using Arduino UNO Rev 3 with RF transmitter and receiver modules. This modules are cheap ones that can be bought at sparkfun or chinese shops.
I've built a standalone circuit on a breadbord with an ATMEGA328P-PU that runs with one 9V battery. In this breadboard the transmitter module runs perfectly. But when I move all this to a stripboard the fact is that it stops runnig (the receiver doesn't get anything). I've spent weeks trying to find out the problem: the voltages at every point of the stripboard are the same than at the breadboard, and I've tested over and over that the layout is ok.
Finally, I've found that I can get the transmitter runnig if I solder it in a separated piece of board, or changing the lengths of the cables that connect it with the microcontroller. But the problem is I don't understand why this happens and I can't predict how is this circuit going to behave.
Any help will be appreciated. Sorry by my poor english (I'm spanish).
Thank you very much!
