No, there's no residual frequency offset.

Are you seeing any over or underruns ("uOuO" or "uUuU") on the console?
How wide is the signal you're trying to send?
What interpolation and decimation values are you using?

Try sending it at 10MHz.

What version of GNU Radio are you using?

Have you isolated the problem to the Tx or Rx path?
