NR for Dummys

[hf4me]

Where can I buy the book?

Let's start with SSB on 3.27 (for me at this time).  Will somebody send me the "non-factory" settings you have changed and what you have them set to that give you the what you see as the best setting (at any particular instant).  I know this will change by conditions, antenna, location, etc. BUT, I would like somewhere to start AND have an idea which settings you change that help you in addition to the NR settings.

Is this impossible?

Huge thanks,

73, de Jim KG0KP

Gary,Jim and Robin,I am pretty satisfied with 3.27 NR and I will answer all your questions off the group and also I will send you guys a MP3's for CW and SSB  showing how well my K3 works when engaged the NR but right now I a not at home,I am at my work office,tonight when I be back I will answer all your questions about settings,meantime enjoy your friday,73

I think a lot of folks would be interested in your findings and those of
others, so, you would do us all a favour if you could put those answers and
clips in a place we can all view: perhaps the Elecraft site?

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.
