I'm still playing with the 3.27 NR, but I like it alot. I operate CW only and have been using the F1-x filter section mostly because it seems that F2 through F4 are minor variations on the F1 theme, so to speak; but I will try them later. With CW signals of course there is not as much subtlety involved as SSB-- you mostly either hear them or you don't. So for SSB maybe there is a bigger difference between F1-x and F4-x.
In general... I haven't found any signals yet that the NR loses when it is turned on, so that is good. True, I also haven't heard any unreadable signals that the NR makes readable, but I am probably pretty good at ignoring the distraction of noise and QRM myself. The NR (especially F1-4) gives the impression of a very narrow filter, but used with a wide bandwidth (2.5 KHz typical for me) you can hear the widely separated signals-- it is an eerie and pleasant effect. I am beginning to trust the NR so I can leave it on and tune across the quieted band knowing it will not miss any signals. Anyhow, here are the settings I am using. You can try them for a start. YMMV, as they say... AGC Slow AGC Threshold 8 AGC Slope 1 AFX Delay 2 RX Eq Flat 0db CW Pitch 520 Hz (typical) BW 2.5 KHz (typical) Cheap Sony MDR-210 headphones (probably should get something better) BTW, someone else mentioned being able to copy signal pitch down to 50 HZ in the previous beta; I can copy comfortably down to about 110 Hz with the above setup. I am used to using a receiver with AGC turned off, AF Gain at max, and adjusting the volume with the RF Gain. But the NR+AGC is a lot more convenient (don't have to keep riding the RF Gain control) and, so far, just as effective as far as I can tell. Can't really compare the NR to the earlier versions because I didn't use it all that much. 73, Drew AF2Z On Fri, 28 Aug 2009 00:29:09 -0500, you wrote: >Where can I buy the book? > >Let's start with SSB on 3.27 (for me at this time).
