Hi Dudley and Rich,
Yes, I've used AGC-T and AF gain to improve reception. Adjust them accordingly
as needed, AGC-T usually between 60 and 80.
Have not had to deal with pulse type noises, so have not had a chance to
exercise the NB.
Tnx for your replies,

Guys,
Rather than use the NR, I use the AGC-t gain, much more effective than any
NR. The AGC-T control should be your most used control. Now if you are having
pulse noises, NB is more effective.

I agree Dudley and thats exactly what I do. AF gain sits at 50 and is
rarely ever adjusted. I adjust volume with the AGC-T control and except
for the case where the desired signal is very weak and in the noise the
noise level is greatly reduced or for stronger signals completely
eliminated.
Hi... wondering if some experts out there can verify...
In playing around with the Flex-3000 and Flex-1500, it appears that the Noise
Reduction (NR) algorithm becomes progressively less effective as the filter
bandwidth becomes narrower. That, in turn, indicates to me that the NR
algorithm is
Hi Dave,
No expert, but I have noticed the same issue here with the Flex 1500, since I
mainly operate CW, it is one of the few disappointments with the radio.
On SSB there is a noticeable improvement in noise reduction at my QTH(using 2.7
to 1.8 kHz bandwidths), but on CW, using narrow filter
Yes, I definitely notice some audio artifacting when the NR is engaged.
Running a 6-core AMD with Windows 7 64. Haven't *quite* it optimized per
the various instructions floating around, but the NR on 2.0.16 seemed
much smoother.
I filed away a post about tweaking some of the settings in the DSP
I seem to remember an email about the NR Function, I can't seem to find any
reply to the problem. My F5K has the problem of the NR having to be re
selected after a period of time maybe 1-2 minutes it slowly goes' to
nothing and has to be reselected. Any comments ? SDR is 2.06 SVN 3804.
Ron,
This in in the bug list to be fixed (DE94).

For starters try the following settings
Under Setup click on DSP, then under the NR try
Taps: 40
Delay: 30

On the ANF try these settings
Taps:68

Gain:70
Hope this gets you closer to what you would expect to be hearing
O yea also VERY IMPORTANT, be sure to

I have been fiddling and messing around with the NR button on PSDR since
July, and have never been able to get it to reduce noise at all.
I was told that it needed to listen and learn about the signals for a while,
so I went to experimenting with making a little change to one of the three

Mike, Which one of the Bhi Noise Away Modules are you using?
Thanks and 73's

What has happened to the NB/NR feature...my TS930S does a much better job.
This feature used to work very well! Tom

Hi everyone,
For some time, I've noticed that the Noise Reduction seems to have almost
no effect. At least no effect in CW mode. I'm running a SDR1K Beta
v1.10.4 SVN 1829. OTOH with v1.10.1 I get really effective Noise
Control with Block LMS and a gain

I incorrectly referred to the noise reduction as NB. I should have said NR.

The evolution of the SDR1K software has been stunning over the past
month...it may be a good time to sell the RX-330B !!
What are the issues with developing some nice noise reduction algorithms for
us SWL'ers? (or recycling something already used by the other modes)
