| Auto-spot consistently tunes to a tone 50 Hz low (50 Hz below
| the value set for pitch).

CW auto tuning to my XG1 on either low or high O/P setting auto tunes to 
my 650Hz pitch setting.  Confirmed by Spectrogram 16 display.

With BW set to 1000Hz the capture range, in my case with 650Hz pitch, 
is -220Hz to +195Hz at 1 microvolt I/P signal.  Outside those limits it 
can take two pushes of SPOT to auto spot, or much beyond those limits the 
auto spot will tune the wrong direction.  However I feel I'm not that tone 
deaf that I can't get to within +/-100Hz by ear.
