Hi Halldór

My is grabber is up and running with "DFCW-6000.usr" now= , but I am probably "completely blond" because i can't figure out&n= bsp; how to "use the sample rate detector to lock your sound card to= a stable signal” .  I need some help here ;)

Steinar

 

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 sugges= t to use a even narrower FFT bin width like 424 uHz. Also a w= ell configured noise blanker can easily help to get another 6 d= B 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 experiment= s 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 fi= nd  under "quick settings/Slow Morse(..)" in SpecLab, but f you have a better solution, I will be happy to try it.
