#189623 - maybe it's the timing generated by that USB-to-serial module
Responding to: Narendra Jha's previous message
USB sometimes introduces delays not found in a normal serial port. This sort of delay can cause the RF module to start too late, or even too early.

That's what I was wondering about. Why not try the same code and RF-hardware without the USB. You'll simply need an old PC to investigate this.
