Hi,
To answer the question...
Notebook is a Toshiba Satellite Pro 425.  It is a 100 mHz Pentium and 
uses an ESS688 chip set built in <<http://www.esstech.com/>> so it cannot 
be changed.  I updated the driver with no improvement in compatibility 
with SPECTROGRAM, HAMVIEW and others.  The problem seems to be that most 
of these programs switch to a DOS window and expect to communicate 
directly to the chip set assuming it is a Soundblaster.  In the notebook 
this ESS688 chipset seems to be different from the Soundblaster and 
compatability is achieved through the WIN95 drivers.  ESS does not offer 
a DOS version of drivers which could resolve the compatibility.

The one software package that does work is FFTDSP from Mike, AF9Y 
<<http://webcom.com/af9y/>>.  According to the docs it provides 2 Hz 
cells and can be set to integrate at least up to 99 fold.  It has an FFT 
bin-to-pixel transform that can be twiddled or put into an "auto" mode 
which seems to be pretty good.

Andre', please forward to Marco.

Spectrally challanged,
