Gary, The HiCut and LoCut are quite useful for SSB. To maintain intelligibilty while the width is narrowed, the low end must remain at about 300 Hz, while the High end can be reduced dramatically.
For use with CW, the shift and width controls are more useful - just reduce the width, and the center frequency stays the same (usually at your sidetone pitch). Slight changes in the shift control may be in order, but normally it will remain fixed. 73, Don W3FPR On 11/24/2010 9:32 PM, Gary wrote: > Thanks Nate.
