Changing SHIFT and WIDTH granularity to 10 Hz from 50 would improve CW useability as well.
A lot of us have formed contest operating habits and tactics based on analog SHIFT and WIDTH functions. Like a combination of a small shift and (sometimes) a lesser width change to put someone up or down just a bit farther down the passband and keep the same skirt frequency on the opposite side of the passband. 73, Guy wayne burdick wrote: > > All RTTY issues noted, Dave -- thanks. > > Congratulations on your excellent showing! > > Wayne > N6KR > > On Jan 5, 2009, at 9:00 AM, Dave Hachadorian wrote: > >> My pair of K3's also worked well in the RTTY Roundup - 1800 >> qso's.
