Hello Robert,

The firmware uploaded to pic is the same for every device. Therefore, all the RF frequency are the same. In this case, 433.1MHz (RXQ2 allows the range 430.0 to 440.0MHz, 200kHz step).

About the RXQ2 exchanging test, I have done that today. And the answer is: Still the same weird thing. The board with 2MHz crystal gets further than the 4Mhz one....

So, the RXQ2 is not the problem.. then, what is it???
