Hi Patrick,

There seems to be a bit of a problem between the driver and libusb, although it worked on Windows and OS X. At some point I'll try and look into the issue, but for the moment I've reverted the changes to the dwell and sample rate settings. Give the latest commit a try and see if it works for you.

The local oscillator is positive for up-converters, for example with a 100MHz up-converter scanning 30-40MHz the dongle would scan from 130-140MHz. 1998MHz sounds very high and I think the dongle frequency may be wrapping around somewhere. If you're scanning above 2GHz with a down-converter the LO should be negative. I'll update the documentation to make this clearer.
