Description
To make the data compatible with readers used for DFB3 data etc, we need to invert the sense of the bits in the data string. That is, after we reverse the order of the bits within each byte, we need to change 0s to 1s and 1s to 0s (use the complement function).

To clarify, the output from DFB3 was changed to conform with the way the 70cm data was written (rather than the other way around), so the change was not needed.
See source:src/pvo-block.cc, comments in DataBlock::readData()
Note: See
TracTickets for help on using
tickets.
It has been resolved that the bit inversion is not necessary for the 70cm data, so this functionality is not implemented.
