Hello John,
I'm still testing the new 5.08 Version. At a first glance it seems that
I can still read slow CW when this is not possible on the old version
(4.2.6.5)! I'm using the same settings (for 3sec dots): 5k5/16bit/Mono,
30dB, 200ms, 16384 points, 360-446 Hz Band, 4-8 times spec average, no
color mods. For 10s dots I would just set the time to 600-800ms.
The signal comes from the Harris RF599 (BFO -400Hz, BW 250Hz -6dB, 5ms
AGC, line out), passes the Timewave DSP599zx (400Hz center, BW 80Hz
-3dB, AGC on, noise reduction on, line out) into a Dell Laptop 300MHz
P-II with 64MRAM.

73 de Toni

PS. Version 5.0 did not work properly with my setup.

No one came back on my Spectrogram comment yesterday - does anyone use 5.08
and what settings have you found best for 10 sec dots?
