Think I have located the problem - no 3.3v on the pin 2 of IC2. When powered up IC2 run hot to the touch.  There is 5.1 v on pin 3 (vin). Verified R7 and R6 are correct values. I have looked for a pinout diagram for the Rf module but could not locate one so don't know the pin numbering on the module. But would seem without any 3.3v from IC2 it wont work. there is 3.3v when powered off on, I assume pin 22 of the RF module
