Garry it is interesting to read you have to use 1020hz correcton for ARGO
 for 100hz tone. I ran into the same correction(1020) on 
two Gateway Profile III's I use for ARGO. Earlier computers I used were
 dead on at 1000hz, even an IBM 166mhz Thinkpad.
My two TS50's are within 1hz. I was lucky that when I started the
 equiupment was close or I wouldn't have copied anything!
I've managed a copy of Warren's XGJ on my Elektor SDR but no luck so far
 with John's Wolf signal. I have copied XES wolf when he 
was running higher power using the TS50, but at lower power no luck with
 the TS50 either.
WEB is off due to power supply malfunction,  so I'll have to wait untill
 he is back on to check the part 15 performance of the Elektor.
I wonder if the jitter problem would show up on Psk-31. I dont have any
 other way to evaluate mine.
The software I use, By G8JCF, for the Elektor allows the filter bandwith
 to be adjusted by the scroll wheel on the mouse. For instance
I can find two cw signals, one at 800hz and one at 1300 hz, on 2khz
 bandwith and lower the upper filter limit to 1200 hz and eliminate the
1300hz signal. Filter skirts are 50hz in width.
Thanks for sharing your experience with the RFspace SDR.
