Re: [Elecraft] [K3] The Way We Rank Receivers (long)
The main commercial interests in subjective audio noise reduction, particularly for speech, are probably the hearing aid industry. It is subjective because noise reduction only really removes noise that isn't interfering. That is still useful, as whilst the human brain can also do that, it gets tired in the process.

It would take some real effort to quantify the world of noise sources and their signatures and then find some algorithms to deal with them. Impossible? The world of big data isn't so big any more. Such an catalog might be doable. Algorithms are another issue. My hope is that NR/NB could be made adaptive to recognize the signature(s) and generate appropriate algorithms on the fly. There are a lot of smart people out there who could perhaps address these issues. Unfortunately commercial interests have to see some payoff. They haven't as of yet. The fact that AM broadcasters are being burned by RFI and becoming proactive is a plus. __ 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 Message delivered to arch...@mail-archive.com

Re: [Elecraft] [K3] The Way We Rank Receivers (long)
OK, I can't resist. I turned on my KX3 at about 0018z on Oct 26. It was set up for 20M PSK tuned to 14.070 with a DSP bandwidth of 2.5KHz. I showed one bar (S1) of S meter with occasional flashing of the second bar (S3). The preamp was off and it was in DATA A mode. The antenna is a 2 element wire beam at about 20 feet. There were no obvious signals on the PX3 -- the band was closed. I am at the family house in Peterborough NH, about 1.5 miles from the village and some 500-1000 feet from the nearest other houses. We do have some CFL and LED bulbs in the house, some of which are turned on. 73 Bill AE6JV On 10/25/16 at 2:43 PM, wun...@wunderwood.org (Walter Underwood) wrote: Good point. Looking at the photo of my KX3 on top of Mount Willson in Henry Coe, I see two bars on the S-meter on 20 meters. That is miles from Silicon Valley. It was quiet and lovely, I could hear everybody. The filters were wide open, preamp on, and NR off. Zoom in and you can see for yourself. --- Bill Frantz|"After all, if the conventional wisdom was working, the 408-356-8506 | rate of systems being compromised would be going down, www.pwpconsult.com | wouldn't it?" -- Marcus Ranum __ 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 Message delivered to arch...@mail-archive.com
