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.
