Re: [Elecraft] Is NR effective on ssb?
Hi Oliver, i think there is a big misunderstanding how NR works. NR is not able to conjure a voice out of the dark. If a signal is not readable without NR, you won`t have luck with NR enabled. It only makes it more comfortable to listen to. 73 Michael -- View this message in context: http://n2.nabble.com/Is-NR-effective-on-ssb-tp4577614p4588304.html Sent from the [K3] mailing list archive at Nabble.com. __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

Hector -- THANKS for sharing your settings. In particular the NR F5-3 for SSB. It's a sweet spot! It makes a weak signal more comfortable to listen to (no, not a miracle) while stronger signals are not so distorted or harsh. I had overlooked this particular setting in my frustration with NR -- too many choices. Now I'll use it regularly.

Re: [Elecraft] Is NR effective on ssb?
Hi John - that product performs very similarly to the GAP ANEM at a much lower price. The technology is the same. In fact, the GAP ANEM performs significantly better than many other IF based DSPs including the one in the K3. I somewhat regret having sold the ANEM now, but with Lyle's modifications to the firmware, K3 DSP performance is getting a little better, but still quite far in terms of what I consider ideal. The downside to the ANEM and many other AF based units is that it will not work properly with CW. The algorithms used in the ANEM are only effective at isolating speech waveforms from noise signals. The link to the ANEM is here: http://www.gapantenna.com/hearit_nem.htm BTW, the GAP product is the same thing to the BHI units; just rebranded for sale in the US. 73 de James K2QI *Disclaimer: I don't work for GAP or BHI, but do know a good product when I see/hear it.

Re: [Elecraft] Is NR effective on ssb?
David, This is exactly how I would describe all the audio A-B examples I've seen/heard posted on the web, including Hector's and the ones with the LINGUA audio processor posted by Juergen. http://www.ing-michels.de/audio_demonstrations.html Maybe that is all we can ask. Oftentimes, when I'm tired and the band is disappointing, the noise begins to sound TO ME like speech. If a human can't tell the difference reliably, how can we expect a DSP to do so? For me, in my very high noise environment, even with the RF gain backed off, the noise interacts with the NR to give a hollow ringing cavern effect with the voices at the very back of the cavern. Unless the ssb signal is pretty strong in the first place, the NR does not improve my experience. But I'd still like to learn how to do it. If someone in a similar high-noise environment has found the magic settings, please post them for the rest of us to try. 73, Oliver W6ODJ On 16 Feb 2010, at 2:13 PM, David Woolley wrote: Research by the hearing aid industry suggests that noise reduction reduces listener fatigue but does not increase speech intelligibility.

Re: [Elecraft] Is NR effective on ssb?
I put the BHI DSP unit in the FT-817, and was amazed at how well it worked. It is the best audio dsp I have heard. As mentioned, it isn't great for CW, but somewhat usable on the lowest strength. I haven't had much of a chance to really try the K3 NR on SSB, but NR hasn't really pulled any signals out of the mud in my experience, but makes them a lot easier to listen to.

[Elecraft] Is NR effective on ssb?
Folks, I wonder if anyone has an A-B comparison audio recording that shows a SSB signal that is UNINTELLIGIBLE with NR off become INTELLIGIBLE with NR on? (Note NR, not NB which is a different animal altogether.) Maybe it is my ultra-high-noise urban environment, but I have not found any combination of settings of NR, RF gain, AGC, etc., etc. that lets me copy a SSB signal that I can't already copy without NR. And I use the good Yamaha headphones that have been discussed on the reflector. My theory is that S8 noise flummoxes the NR algorithm so much that it actually becomes a hindrance. Maybe it can't really distinguish high noise from voice. This is not to criticize Lyle or the K3.

Re: [Elecraft] Is NR effective on ssb?
Hi John, Yes, seems impressive. Uses a the envelope shape of the speech waveform to distinguish it from noise. The examples, however, do not meet the test I asked about: Is something UNINTELLIGIBLE without the device and then INTELLIGIBLE with it? Also, it is a bit pricey at some $300 to $400. Otherwise, I might be tempted to try it. Many thanks for the tip. I'll keep my eye on that product.

Maybe it is my ultra-high-noise urban environment, but I have not found any combination of settings of NR, RF gain, AGC, etc., etc. that lets me copy a SSB signal that I can't already copy without NR. And I use the good Yamaha headphones that have been discussed on the reflector. My theory is that S8 noise flummoxes the NR algorithm so much that it actually becomes a hindrance. Maybe it can't really distinguish high noise from voice. This is not to criticize Lyle or the K3. I imagine that these algorithms have their limits no matter what radio they are run on. 73, Oliver Johns W6ODJ __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html -- Robert G.
