If NR was available on data, it would be expected to work by the newbies with endless complaints, even if there were mounds of reports out there saying why it shouldn't be used. Then the vagaries of digital operation would be blamed on Elecraft. Each digital mode has a specific collection of clean detection tricks that belong in the PC software, not the K3. My gut lurch is that NB probably needs to be X'd out as well.
