[Laser] Linux software for sig processing

[Bob Williams]

A note from Erik Olson (writer of baudline) quoted with his permission:

"I added (fixed) a feature in baudline 0.90 that might help you pull out your
laser cloud bounce signals. �The old drift integrator never worked correctly
while in the record mode, now it does. �This will lower the variance
�(flatten) the noise floor making it easier to detect weak tones in real-time
�while you are recording. �I still have a ways to go �inorder to optimize it
�for your line of work but this is progress.

Try setting:

the overlap to 100%
the drift integrator to 4 slices �(experiment, more or less might be better)

Because the noise now has less variance you can use the "color aperture"
window to squeeze down on the spectrogram color range a bit more which
should increase the color resolution...."

Erik seems interested in adapting this program for use by laser, LOWFER and 
MEDFER people. �Contact him if you're interested in using his software or 
would like to see some changes.

Another linux program is glfer, a QRSS transmit and receive program for 
linux. �I haven't tried it yet....
