I have just uploaded version 0.99 of Jason on the Web site.
The main improvements are :

- I/Q outputs for phasing up-conversion
- Following the suggestion of Stewart Nelson, I made the amplitude and
  the phase of the right channel "tweakable", to compensate for
  unbalances in the hardware.

The amplitude adjustment has a range of 0.95 - 1.05, while the phase delta
can be changed from 89 to 91 degrees, with steps of about 0.01 degrees.
If these ranges are deemed too small (or too big), just tell me, they can be
easily changed.
To use this calibration feature, open the Options menu, then Tx Port.
Please test if everything works ok, especially the phase adjustment, I haven't
tested it (yet).
