Stefan:
Just to be sure everything was OK, I transmitted (using a ferrite rod 
Tx antenna!) a marker at 136170.000 Hz and to my surprise, it showed 
up on your version about half a Hz low!  I had not entered a close 
estimate for the 48000 sampling rate and apparently SL locked onto 
something else?  I measured the actual sample rate at 48000.10944, 
entered that and thereafter the displayed line jumped right up to 
136.170 Khz.  My usr uses 22050 (which is actually 22200.0653), but I 
had already typed that in last night.  I'm not sure how Windows XP 
handles things when two applications are inputting simultaneously 
using different sample rates.  At this time both instances have the 
sampling rate correction enabled and the TS-850 is still set for CW 
mode 500 Hz narrow filter - that's the way your .usr file assumed 
it.  At some point while I was measuring things SL appeared to redraw 
the LF_EU60 display and now both versions show the marker on the same 
frequency.  Almost as if the two versions were comparing notes :-) 
I'll either take the marker away or turn it off if Mal wants to use 
that freq.  I am using V2.77 b02 of Spectrum Lab for this test.
73,
Bill VE2IQ
