We will try to get to the bottom of what is going on here, but in the meantime, you can try using HDSDR with the RSPduoMTG wrote:The plots are showing a calibration signal level and not noise levels. The signal was on the input to the RSPDuos continuously before, during and after the "Stop" - "Play" sequence. The level drops not only at the start but at other times and the calibration signal has not changed. There is also an antenna on the inputs and the background noise will naturally change. I was hoping to use the Uno - Duo kit for some radio astronomy applications where I will need to stop and start things during the experimental and set-up stages and clearly these changes are a BIG downside. The equipment is touted for scientific use but the supporting software is not quite up to it yet it seems ....
Are there any alternative SDRs for the DUo hardware?
