@brendanthebig I think this is more because of changes made in the LimeSDR plugins. Now the center frequency is the actual center frequency taking NCO into accoun with the NCO dial showing the actual frequency shift. Before the big dial was the LO frequency and the NCO dial the actual center frequency. I think this was a bit confusing moreover it messed up the center frequency if you use the preset with a device not having a NCO (anything else than a Lime). You can still see the actual LO frequency in the center frequency tooltip message. If you use a preset saved from an earlier version it will not interpret the center frequency the way it does now. So indeed loading and correcting then saving with the new version should solve the issue for future preset loads.
@martywittrock I am also waiting for things to mature a bit on the LimeSuite side. I was still able to get a clean Tx modulation from a Lime-USB attached to my Windows7 machine. The Lime-mini Tx is messing up in all cases.
