Yes, I too have Phonak digital hearing aids the VA gave me. They are very effective, and have 4 or 5 "programs" which adapt on the fly. That said, the "noise" they work in does not really resemble on-the-air power line and similar noise. Mainly, they help me sort out someone talking to me from other voices in the background. They do suppress wind noise when driving, and will notch a fire truck or ambulance siren down to tolerable levels. They truly did change my life and my thanks to the US Taxpayers for that, I think they run about $6K a pair. If only I could get a cable that plugs into that tiny programming jack the audiology clinic uses and plug it into the radio :-) I've not found my K3 NR to be all that useful. On CW, it does raise the apparent S/N some, but the signal sounds "pinched" [best description I can come up with] and if there is QSB, it seems to accentuate it. APF is far more useful for me. I'm rarely on SSB, but when I am and use NR, the speech seems to become distorted and far less intelligible. After playing around with it for awhile, I think I think there are too many menu choices for my feeble mind. OFF, LOW, HIGH might be better, or perhaps ON and OFF? 73, Fred K6DGW - Northern California Contest Club - CU in the 2011 Cal QSO Party 1-2 Oct 2011 - www.cqp.org ______________________________________________________________ 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
