Thanks Wayne,
This is a welcome feature for PSK31 ops, I often shift and narrow the
passband to center on a signal when conditions are poor or there are a lot
of strong signals on the waterfall. Having the 10 Hz resolution really
helps. But... (there's always a "but", isn't there? ;-) )
When set to 10 Hz steps, the range of the passband shift range is greatly
reduced -- 1.28 to 1.72, as opposed to 0.40 to 2.20 when set to 50 Hz
steps. Hope this will be corrected in the final release version.
