I operate a lot on CW nets, with the b/w set to 700Hz, no EQ, AFX on, and use the NR to increase the apparent S/N ratio, and also to soften the effect of band noise on the ears. Before v3.25, this was frustrating because the NR took appreciable time to build the filter, and appeared to do so on each code element; the overall effect was to make the code sound "mushy" and harder to copy.
Then v3.25 came along, and it made a big improvement. The mushiness was gone and by experimenting with the various settings, I could find a "sweet point" where the filters were not too aggressive and yet an appreciable improvement in copy was obtained. With v3.27, the filtering became even more focussed and this morning I used a 3-3 setting to pull weaker stations out of the noise on 40m, which was having one of it's less stellar days. I think the guys at Aptos are definitely going in the right direction, especially for the CW side of things. I've tried the NR on a couple of SSB nets, but there the improvement was less easy to pick out -- though I think it IS an improvement when you find the correct setting. Not a scientific review, just very subjective $.02 worth. 73, Van W1WCG ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
