I've been watching this thread with interest. For a few years and several different radios, I've been repeating the same test: 1) Tune around with a bandwidth of about 400 Hz. Find a weak CW signal close to the noise which I can't copy 100%. 2) Try all the possible techniques to improve intelligibility, looking for the ones that improve the percentage of copy. Here is what I've learned: 1) If there is a kind of noise that a NB will reduce, that helps. 2) If there is not too much noise, reducing the bandwidth further helps. I sometimes go down to 50 Hz. on the K3. But on a noisy band this makes it worse. 3) AFX doesn't matter one way or the other. 4) Dual-diversity reception (polarization diversity) *REALLY* helps. IMHO this is one of the K3's greatest features. 5) NR doesn't help with the weakest signals. 6) I can't decide what pitch is best. Usually I use around 500 Hz. but that's because I like the sound of it. -- 73, Vic, K2VCO Fresno CA http://www.qsl.net/k2vco ______________________________________________________________ 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
