Felix,

Thanks, it all makes perfect sense now ! Will have to tinker with my code a little further....

BR Peter.

The header and CRC are validated and processed at the programmer Moteino (or gateway if you want to refer to it that way), in the HandleSerialHEXData() function:
https://github.com/LowPowerLab/WirelessProgramming/blob/master/WirelessHEX69/WirelessHEX69.cpp

As a side note, I always use a "wireless programmer" Moteino dedicated for that purpose. I don't use the main gateway of the network since I don't want to interfere with the normal operation of the network.
