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.

Thanks Bill ;-) The webpage looks fine! :-)
At G4WGT i can see Mal TXing nearly 136.172. Will he join in? Oh, it
seems i really have to finish that PA supply ;-)
Looking forward to that evening! Unfortunately there will be some
rain it seems. That may cost a dB or so...
