I saw the "Eye" mentioned in the manual a few times. but the entire pass, to elevation about 50 degrees, never once decoded anything.

I selected the FCDP+ from the pull-down. That defaulted to 192K. on the graph was "sample rate = 48000 samples 70" I'm guessing there were no other things to set on the front page.

One more chance in an hour if I can get help on the FCDP+ as I gave up on modifying my IC910 SignaLink cables.
