Alan,
Thanks for the suggestion. It works.
By using one USB slot on the front of the computer and one on the back I got CFGSR and the Behringer to work together. It even works at 192 KHZ sample rate, so I can see at least 180 KHz wide on the waterfall. However, the noise level is a couple of db worse than the Delta 44, and both are about 10 db worse than I remember (some time ago) with the Delta44 and a little softrock lite 6.2 crystal receiver as a panadapter on an old icom USB -only radio.
So:
A) What did you mean by softrock modification? Is there a way to get the noise lower on the RX ensemble II?
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.
