Concerning an 'adjustable spacing grid' to improve DFCW reception:

The recent versions of Spectrum Lab had a 'time scale' for the waterfall,
wich can be set to any interval in the range of 1 second to several hours.
This "time grid" is a kind of overlay on the waterfall, so it scrolls
together with it.
If you set the interval of the "Waterfall Time Grid" to 4 seconds, you should
be able to see where the dots are (if YOUR and the transmitting station's PC
clock is set properly). I guess this is what Mike ment in his recent posting.

BUT:
I am currently adding a few new functions and improvements to the program
(tnx DF6NM), so maybe you better wait for the next release. The currently
available version is V1.63, still available at www.qsl.net/dl4yhf.
Spectrum Lab is not as easy to use as Alberto's ARGO, because it was never
intended to be a simple QRS viewer (more a 'platform' for own experiments).

Hope this helps a little.

Good luck,
Wolf (DL4YHF).
