A) What did you mean by softrock modification? Is there a way to get the noise lower on the RX ensemble II?
David,
The discussion was long ago, before the Ensemble.
But basically involved reducing the opamp gain. It may have made a difference in extreme cases but the dynamic range of 16 bits may be better than many modern SDRs with 12 bit ADCs.
B) I have large noise bumps every 60KHz across the spectrum. Could be from the big Monitor of the computer or a Class D audio amp. Lots to look at.
Best of luck with that! There are so many potential interference sources.
