It is a known issue with the current operation of the NBs. What you are hearing is a consequence of the NB algorithm currently used in PowerSDR and is not related to the AGC, but the gating on/off of the receiver (which is sampling much larger bandwidth based on the sampling rate) which is mixing strong signals into the RX passband.
There are better ways to implement the NBs, such as pulse noise subtraction that are on the DSP drawing board. -Tim -----Original Message----- From: flexradio-boun...@flex-radio.biz [mailto:flexradio-boun...@flex-radio.biz] On Behalf Of Leo Hoffmann Sent: Wednesday, November 17, 2010 4:17 PM To: flexradio@flex-radio.biz Subject: [Flexradio] Help Noise Blanker When I turn on the Noise Blanker while listening to a QSO I can hear another station up to 15kc away. It's more of a pumping sound vs. actual conversation. The NB default is 20 and I have tried going up and down to no avail. Also tried different settings of AGC. I can have the NR on or off and the problem still is there. Using Beta 2.0.16 Vista 64. duel core. i7 Intel processor I didn't have this problem prior to the Bata change... Your help would be appreciated ..wb0yol..Leo ======= Email scanned by PC Tools - No viruses or spyware found.
