Perry,

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.

73,
Steve G3TXQ
