Tony ..... Yeah, I couldn't have said it better about the NR as it is now - you nailed it. See what the next few DSP f/w's have!
I had an IC 746 (not PRO) - the NR on it was great .... and it was just that - Noise Reduction, pure and simple. We took it to V47 about 6 years ago and it was almost as good as the K2/100 w/o the KDSP2. Wish I'd have never sold the 746! 73 Hank K8DD N2TK wrote: > I do see a reduction in audio when turning on the NR with SSB.
