Linrad could in principle do anything that is not
protected by copyright or by the GNU license.
For protected things a dll or corresponding Linux
module would be needed.
I do not think it would be any good idea to use
a second Ozy because frequency/phase synchronization
would require many signals between the Mercury boards.
I hope the design was made originally to allow
more than one Mercury on the same backplane using
the same OZY board. There have be lines to synchronize
the FPGAs on the different Mercury boards and
running them from synchronized sampling clocks.
As far as I understand one can phase lock the boards
to a frequency standard so that part should be

I really do not know. I have not been able to
understand anything of Mercury or Quicksilver/QS1R
It would be fun though to have direct support for
Mercury and Penelope in Linrad. Particularly if
2 or more Mercury boards were allowed:-)
