Hi,
Can you post a picture of your project so we can see your component layout?
Can you please post a copy of your circuit, in CAD or a picture of a hand drawn circuit in jpg, png?
We need to know how you have connected EVERYTHING connected in a diagram including power supply.
Component layout and how you wire your power supply to those modules is very important.
What frequency is your Tx working at and do you have it transmitting into a TUNED aerial?
Thanks.. Tom..
