Bill,
I just checked and you are correct; it DOES zero-beat to the center of
the currently set filter.
However, if the traditional notion of zero-beat is inferred, then the
expectation is that tuning a signal to match the desired 'cw pitch',
would place one's transmit frequency on the same frequency as the signal
being tuned. IMHO, the zero-beat function should operate this way, i.e.
matching the user-selected 'cw pitch', regardless of where in the
passband of the current filter the signal may be located.
There are good reasons for using a wide filter that is shifted such that
the desired signal is just inside either edge of the filter passband.
Zero-beating to the center of that passband, could place the transmitted
frequency several hundred Hz away from the desired signal.
Even better than a zero-beat button - how about a one-keystroke toggle
between panadapter and spectrum modes so that we can use the increased
resolution of the spectrum mode to visually zero-beat the desired signal
with a single mouse click. Seems to me I've heard this mentioned
somewhere else before ... :-)

Hmmm ... will have to look @ that. Thought it was set to zero beat to
center of currently set filter?
Will look into it -- opinions on if CW pitch or center of current
filter is correct zero beat point?

The CW zero-beat function works great and is much appreciated!
However, I suspect the intent was for the zero-beat to occur at the
'CW Pitch' frequency that is selected in Setup > DSP [CW Pitch]. My
zero-beat occurs at 600 Hz, regardless of the selected CW Pitch.
