Are you seeing the 1 MHz offset when you use the uhd_siggen.py? Or is it
just with the OFDM transmitter?
What is this tool doing? Transmitting a sine and checking the offset.
Sorry, for the moment I have no possibilitie to check that.

@Tom
does that mean that there is only a coarse frequency correction
implemented? How could I overcome the offset in the easiest way?
Checking it by usrp_siggen.py and adjust in manually or are there some
smart correction algorithms implemented?
