The presence and position of the 'waterfall colour to dB' legend is configured
in SL's Screen Capture settings:
Set the checkbox 'color legend'. You can also select *where* (in which corner
of the screenshot) that 'legend' shall appear.
Uploading captured images via FTP requires a command-line driven external FTP
There is one integrated in windows, but it's so terrible to use (and
control) that I would try something different. You need to create an
old-fashioned batch file to do this (if no modern FTP client is available):
The FTP upload command can be invoked from the 'screen capture extension
macros'. These commands are invoked shortly *after* every timer-driven screen
For more details, I suggest to ask the question in the Spectrum Lab Users
group, there may be users more familiar with command-line driven FTP utilities
under Windows 7 / 8 (which I hardly use myself).
Hope this helps,
73, Wolf DL4YHF .
