I haven't tried it. If I get a chance over the next couple of days I'll
do some tests.
It would be nice to get some thorough testing done of Rx performance
when equipped with the DDS, but I don't have the kit to test things like
close-in DR. I can't say I've noticed any deterioration during my
"casual" operating, but I wouldn't be surprised if there was some
penalty compared to the PTO. I'm in the enviable position of having one
Corsair with the DDS, and another Corsair with the PTO plus remote VFO;
that's the way I intend to keep it for now.
