    Been trying out several programs (like SDR Sharp) and others to play back some IQ files I recorded off of KiwiSDR. My latest program candidate is Spectrum Lab, but having trouble figuring it out. There are many more variables than any of the other programs I've tried thus far. The only thing I have been able to do so far is play an IQ file at the incorrect speed (voices too low), but can't adjust things like passband, frequency, etc. If anyone can provide some pointers or a tutorial/ quick start, please share.

    Please note that this doesn't have to do with an actual SDR set up; all I want to be able to do it play the recorded IQ files correctly with adjustment capability.

    Hi Eric.
    I haven't used Spectrum lab but I have an Audacity plug-in written by a good friend of mine which can replay an I/Q recording from a Kiwi SDR. It works very well.
    If you are interested then please email me off list and I will put you in touch with the author, in Australia.
