Hi Jacek,

It sounds interesting and this is great that you are doin= g it for those
that have Linux systems.=   I'm not sure if including SL files in it would
attract Wi= ndow users though...but hard to say.  I'm sure Linux users
= would like to see QRSSS type files if they were made available...
aside from the ones in SL itself. At least it would get them started in
playing with weak signals at ULF & VLF.  I'm still looki= ng on Stefan's
QRZ site and the sub 9kHz/vlfnews , lots of reading yet to do but no such
.USR files like >QRSSS600 found yet for 8270.000kHz. The best I ca= n do
is use SL's 1mHz resolution with SR calibration using a GPS= ref oscillator.

Hello Jack,

I'm currently starting to write a s= hort article about using spectrum lab
for vlf for the klubnl.pl site. C= ould you tell me what you would like to
see there? (example SL configs = etc). We can take this off-list if you
want.

This was supposed t= o be more of an "using Spectrum Lab under linux"
article, but i can inc= lude additional non-linux details if you want. I'm
sure this might be h= elpful for more people.
