When starting my grabber Stefan and Chris thought me
some tricks:
“and use the sample rate detector to lock your sound
card to a stable signal”
That helps if you are using the 60000 window.

Steinar,
600 s/pix. is a good start point for tmw but i would suggest
to use a even narrower FFT bin width like 424 uHz. Also a
well configured noise blanker can easily help to get another
6 dB S/N as we have seen in the past.
I attach you a "DFCW-6000.usr" which you can load into
SpecLab. This was used successfully in many last experiments
on many grabbers :-)
Not you have to wait some 10 minutes until the first pixel
appears so do not wonder ;-)

I had plans to use 600 sec/step 1mHz res. you will find
under "quick settings/Slow Morse(..)" in SpecLab, but f you
have a better solution, I will be happy to try it.

you configure the software (which?)?
