Re: LF: DFCW Parameters

Spectrogram is limited to 0.7Hz resolution (16k bins at 11k sample rate),
so it had little advantage to have dot longer than 3 seconds.
I'm sure that Spectran will make 10 sec. dot (and even longer) more
interesting.
Theoreticaly you can gain 5.2dB by going from 3 to 10 sec. dot length.

PS : I (and I think several others) never got Spectogram running stable at
5.5kHz sample rate.
