I suffer from the high noise floor problem which pretty much makes things useless. To correct I have to shut down SSDR and reboot the radio and its power connection. Once I do that and restart SSDR I can no longer connect to any IQ channels. The channel number lights up but there is no data throughput. So now every time this happens it seems I have to completely reboot the computer to get things working again if I want to use the IQ channels.
