arghh... thanks for that!
I remembered seeing that code but when checked I saw that it was using the full power, 20dBm!
Problem was I checked on the RX and forgot to check on the TX side, so yes I was only using 1dBm
on the TX side. 
If the weather keeps good, I'll test it again with more power.
PS: What have you used to power the TX module? Both Futaba and 9X output 12v so it needs to be converted. For testing I ended up using a ESC+LiPo. So I was wondering if you have a new board layout that includes a voltage level converter.
