Joe and all, As I understand the changes, in the pre-3.27 NR situation, there were audio peaks in the response envelope - so it worked very well (similar to an APF) for some who used a CW pitch near the peaks, but there were others who used other sidetone pitches and they were not happy with the CW NR at all. The peaking in the response made SSB NR unusable for me, but now it enhances the signal while getting rid of the noise - Yes, I hear a bit of 'hollowness', but that is acceptable to me - at least I can hear and understand SSB signals down near the noise level.
The key to finding the right NR settings is to adjust them while listening to a signal - if there is no signal, any of the NR settings can reduce the noise, but it may not be a setting that is suitable for the band conditions, antenna, noise type or signal strength. With 3.27 on 20 meters at my location, I use F1-x through F2-4 on SSB, but the F3-x and F4-x give me some signal attenuation - many CW operators have reported that F3-x and F4-x work well for them on CW. Experiment with it a bit, but do it while listening to the weakest signal that you wish to hear, and you should be able to find what will work best for you under those band and noise conditions. 73, Don W3FPR Joe Planisky wrote: >> Some times you can't satisfy all the people all the time with one >> road. >> > > Truer words were never spoken! > > I'm a full time CW operator (well, 99.9% CW, 0.1% digital modes.)
