Re: [Flexradio] DSP Settings
Anthony, NR will tend to do that, part of the function of all the filtering, adjusting the taps and delay can help, but you are destroying the purpose of the noise reduction.Many Flex users find that just reducing the AGC-T gain is much better than using the NR and then the two adjustable noise blankers (NB1 and NB2) for other peskie spike noises, but band noise can usually be reduced greatly by reducing the AGC-T gain.. Hope this helps. 73, Dudley WA5QPZ Anthony Martin wrote: I'll give that a shot, Do you find it makes the audio hollow and tinny?

Re: [Flexradio] DSP Settings
I tend to agree, no matter what I do to adjust mine, I can always do better by just adjusting the AGC-T and turning up the volume if needed to knock down noise, or thread the needle with it to pop out a weak one. I may just not have things right, but I have yet to find a situation that the NR works better with it on than off. I can't complain though, I'm not a programmer so I have to take what is given to me, and it's free so... what you can you do. ;) Jesse 73 N4BFD http://www.qrz.com/db/N4BFD On Sun, Oct 25, 2009 at 10:16 PM, Anthony Martin < anth...@consultexcel.com.au> wrote: > Yes I am referring to the Noise Reduction.

Re: [Flexradio] DSP Settings
Yes I am referring to the Noise Reduction. I have found that on old physical rigs such as the MP1000 or MP2000 or IC-7000 - anything with IF DSP seems to have better noise reduction. This surprises me because the SDR should kill it.. The version I am using is 1.18.3 I think, the current release on website. I also have 2.0 Alpha installed.

Re: [Flexradio] DSP Settings to Try for Lower Noise
My apologies if the manual does not deal with the Block LMS differences in an understandable fashion. I will look at that soon. Eric and now Joe have done a great job of changing my technical-ese into descriptions but I will look again to make sure it is not confusing. Taps and Delay have no meaning for the Block LMS. They are no-ops. Gain is the only setting. You should be able to set the NB2 threshold more deeply than you can NB threshold. That is its real purpose. If the pulses are so large they exceed the NB threshold, the likelihood is small that the simple neighborhood measurement and sample fix will work correctly. So the much larger pulses should be blanked. Those are exceed the lower NB2 threshold but not the larger, are more amenable on averge to neighborhood sampling and rank order mean subsitution. The third blanker in the stable will be release once we have the impulse response of the system determined. That might eventually replace NB2. With the wider console, there is no need to replace these buttons for now. For those doing CW, single digit gains are the only way Block LMS works correctly. Then it works in pretty spectacular fashion. I will be glad to have our version 2.0 of everything going as we will have unique profile settings for all modes, etc. You should be able to have a complete radio setup stored in your favorite profile to keep you having to set any buttons when you go from SSB to CW and I mean for ALL settings. This is an SDR after all. Bob N4HY Gerald Capodieci wrote: > Try the following settings under Setup/DSP: NR Taps=100, Delay=25, Gain=16, > Block LMS.

[Flexradio] DSP Settings to Try for Lower Noise
Try the following settings under Setup/DSP: NR Taps=100, Delay=25, Gain=16, Block LMS. Noise Blanker: Threshold=17, Noise Blanker2=Threshold=17. I'm in Los Angeles, a very noisy area and these settings make listening more pleasing. Jerry/kd6et -- next part -- An HTML attachment was scrubbed...
