Markus,

When you wrote 'first and second sidebands, I assumed you meant Mark and
Space, but obviously not. My mistake. You are probably right that this won't
cause any problems.

 fair enough, but I really do not think we have any reason to worry about
interfering with SXV. Their FSK is keyed between about 135710 and 135810,

so

we will be well outside their intended modulation band. I would regard the
weak sideband above 135930 as a spurious of their hardkeyed FSK.
