Register Dump
Next step was to dump all registers (0x00 RegFifo thru 0x4F RegTemp2) of the RFM69HCW device.

I checked a selection of values from the Debug output and they matched the defaults in the datasheet e.g. 0x07-RegFrfMsb 0xE4, 0x08-RegFrfMid 0xC0, 0x09-RegFrfLsb 0x00, 0x2C-RegPreamble 0x0, 0x2D-RegPreamble 0x03 and 0x4E-RegTemp1 0x01.
