Beta 2.22 and Noise Reduction problem

[n6wg]

Just finished installing the 2.22 beta.
Took the rig back to the shack and ran through the
various controls I use the most often.
No problem with the Noise Blanker but the
Noise Reduction does not work now.
I went through every menu I could find, and
KNB3 is ON and seems to work ok.  I couldn't
find any menu choices for the NR function though.
Whether I tap or hold the NR button, all I
get is N/A.

Have I missed something or is there a bug in
this beta?

Thanks and 73
Bob N6WG

Bob,

Are you possibly in DATA or FM mode?  The NR function is not available
in those modes, hence the N/A display.
I have 2.22 loaded and have no similar problem with the NR in CW, SSB or
AM modes.

NR does not work if AGC is OFF.

This is because there are some circumstances in which the DSP can be
made to oscillate with NR and no AGC.

Hi Don
As usual, it turned out to be very simple.
Just neglected to check the AGC ON.
Once I changed it, all was well.
Thanks and 73

I am on the list to receive a basic 10w K3 kit, soon.

Evidently, some are using an SDR radio on the IF
output for a bandscope?

Am I way off, here?

Brian....

The band scope is being done using LP-PAN form Telepost and some have been working on using a Softrock SDR device.  The Softrock works, but there are issues with buffering between the K3 and the Softrock SDR.  Some have made buffer amps available.

I have an SDR Radio tune to the output of the K3, but have yet to have time to get it together with the buffer amp.  Mowing the yard in this rainy summer has taken over my life.

Brian,

Take a look here: http://www.telepostinc.com/LP-PAN.html
Lots of fun so far - ever evolving. I had it working for a few hours today
and it holds for a lot of possibilities. Should be practical and cutting
edge at this point IMHO.
