Dear Wolfgang, Daniele, LF,
 
thanks Wolfgang for the hint about tu= rning off=20 periodic actions.
 
There are actually three configu= ration=20 files in
so some explanation is probably on=20 order:
 
-  9kHzWide.usr has 0 to 24= kHz on the=20 top and around 9 kHz at the bottom, with 1.46 Hz FFT resolution= and 1=20 second scrolling. It's meant to give a quick overview of the band, eg.= =20 to optimize antenna coupling. You shold see the big MSK sign= als,=20 and  three lines of tiny dots on the Alpha frequencies. But= this=20 setting is too fast to see a weak signal.
 
-  9kHz_slow2_white is the origi= nal 15.3 mHz=20 setting, with the 8.97 kHz area at the top and 11.905 at the bottom.&n= bsp;It=20 scrolls at 10 seconds, and you can read QRSS 60 or slower keying. Bewa= re there=20 is an offset (0.30 Hz and 0.0397 Hz) on the frequency scales= , which I=20 had used to correct for my "white" notebook's samplerate offset. = But=20 this will certainly be different on other machines, so I would=20 recommend to reset those offsets to zero, and use the samplerate= =20 calibration entry in SpecLab's audio settings tab instead.=
 
-  9kHz_4mHz.usr is the=20 one currently displayed on the lower part of my grabber. It has= a more=20 sensitive 3.8 mHz FFT and 1 minute scrolling. Again, you should delete= the Freq1=20 and Freq2 offsets and enter your samplerate.
 
Good luck to Stefan and all,

A=20 high-res spectrogram configuration is available on DF6NM's VLF grabb= er site=20 (at the bottom). But I guess you already found that one ;-)

A= fter=20 loading Markus' 4-mHz-config, be sure to turn the Periodic Actions= off,=20 because they invoke a batch file to upload a screenshot via FTP, whi= ch almost=20 certainly doesn't exist on your machine ;-)
