Bob Thanks for the new code. My HF noise aboard a boat is atrocious on some bands. The sonars harmonic pulses are gross on 75M and the NB will take it out but high level SSB nearby distorted the audio I would be listening to greatly before. Tried your new test code last night and the distortion looks to be gone or very little at first glance and the sonar pules gone with NB on, wonderful. The ANF seems better and slowly ramps in notch if tone is low level. NR has not really worked for me for a long time and now seems to work, although I need to play with controls to be able to copy weaker signals with NR on.
There seems to be a problem if I turn on both NR and ANF at the same time. The Panadaptor goes flatline midscreen and the audio goes very choppy at about a second interval.This is with 2 nd rec off but this also occurs on 2nd receiver if I engage both there also. Tests are with default NR and ANF settings .If I reduce taps on NR down to 40 or below pan video mostly works ( some freezes) and audio slightly choppy. This may be a problem with too much load on my new PC . The cpu shows 15% normally ,NR on boosts cpu to 28%, ANF on boosts cpu to 25%. Turning both on cpu still reads 29% ( probably bogus )but there is overload on system by evident audio- video failures and if I watch windows task manager the first graph of the 4 cores zooms up to 100% usage. Running test branch N4HY pwrsdr audio at 96 Khz w 2048 buffer I have not had much experience with this newly built PC yet, so can not comment much on it's characteristics. It was running pwrsdr ver 1.16.2 well for a week and had no issues at either 96Khz or 192Khz that I found. It also runs HPSDR mercury-ozy at 96Khz but does have the 192Khz mercury stutter others seem to also have( usb issue ??). I know I do luv it so far and thank you for turning me on to it.I hope that it isn't too under powered for this job, didn't think I needed a quad core 2.8Ghz for just the radios. New PC = Atom 330 w/2Gig ram and WD 500 Gig HD , OS= WinXP pro upgraded to SP3, Trendnet 3 port firewire card all in mini atx case w/250 Watt supply.external usb dvd drive ( hope to mount a mercury/ozy 2 plug mini atlas in dvd case space ) Flex 5000A w 2nd receiver and ATU Again thanks for all your great work and ideas..
