Don, Noise reduction is unavailable for K3 digital modes. You get a N/A when trying to use it. (If you really want to try it you'd have to use USB. A high potential exists for poor copy with NR on.)
Oddly enough NB is selectable. I can imagine some of the higher settings of NB can likewise scramble copy, though I haven't any data to support that. Attenuator on is a good idea if you (and your sound card) can live with the signal strength it produces. 73 de Brian/K3KO On 7/5/2011 23:39, Don Putnick wrote: > After having a less than successful time with PSK31 during the 13 Colonies > Special Event, I think I need to learn more about noise reduction.
