IQ Data File Analysis
The center frequency of a recorded wave file is "painted" as a red marker in the IQ Data File Analysis. Why?
It it not very useful to get this man made interference. Can it be disabled? Please have a look here:

Hi,
This isn’t me – maybe it’s the spur from the IQ? There’s a spur reduction option in the console.
What happens if you shift the frequency by 10Hz?

I always use the spur reduction. But I will check this again next time.
Thanks!

No problem J
The NetSDR doesn’t have a spur...

No "red marker" found when chaning frequency from the "center frequency of the wave file". So if it is not your marker, it must obviously be the spur as you mention. Thanks again.

I have one of them (No. 105), and yes they are more rare than hen’s teeth (as we say in English) and I am available for testing it for Simon if / when required under various versions of Microsoft operating systems. Just to make you jealous, it does seem rather good! Keep trying, it would seem that there is a larger batch in sight, soon, real soon.
