To Clay and all that commented on the Noise Blanker in the FLex-1500. Thanks for the report. Greg and I duplicated Clay's test here today. I now confirm that neither of the Noise Blankers are working properly in PowerSDR 2.0.5 for the Flex-1500. Also, the ANF (audio notch filter) is not working. All were working fine in earlier releases, so likely some kind of a simple control problem. The software guys now have it on their list.
