K3 Firmware 2.19

I think I am about ready to go back to 2.16. I find the receive audio to be too weak with NR and attenuation engaged. Roy Morris W4WFB

Re: K3 Firmware 2.19

Hi Roy,

Try AGC THR = 5 and AGC SLP = 8....and or experiment with varying
those two parameters as you monitor a signal.
My AF gain is at the 9 o'clock position, AFX on, BIN option.

I use a couple of small RCA/Radio Shack speakers.

To my ears, the difference between NR on/off is really close to the
same audio level.

But as Lyle says, experiment, it is quite revealing!!

Best of luck!

Re: K3 Firmware 2.19

Also with my K3 there is a significant reduction in the audio level
when NR is on. I don't see how the AGC would affect the NR. It's just a
function of the filtering that reduces the volume when the NR is
activated. Or is there something I am missing.

Re: K3 Firmware 2.19

Gee, I don't know .... To only say "the audio went up, or down, when I
loaded X.xx" doesn't tell me anything!
What was the AGC SLP? AGC THR? NR settings?
With out that information, yes - it can go up or it can go down when you
turn NR on!

I just loaded 2.20.
The audio went way up when I turned on NR - I was using the XG2, 50 uV on
80M.
SLP= 4, THR= 8 NR= F2-2 and I had really liked the way the radio sounded
with the 2.1x's, but with FW 2.20, NR would hurt it was so loud. Almost
triple while monitoring AFv.

Changing SLP = 14, THR = 5 got the audio real close ..... but the radio
sounds like crap. OK ..... that's a personal observation of what it sounds
like to me on 80 CW!

I'm not sure I understand everything I have read about SLP and THR! Nor do
I want to. I want a radio that sounds close to or better than the K2!

So there's what I think.

Re: K3 Firmware 2.19

In reply to this post by srife

Hi Mike. I have 2.20 loaded and my comments below are what I am
experiencing. I don't see how it's possible to have the same level of
audio with the NR engaged. The filtering will naturally reduce the audio
level, unless the K3 has a gain adjustment for the filtered audio like
the K2 has.

If turn NR on, I have to turn the AF gain up some.

Re: K3 Firmware 2.19

I guess I should also say that this has always been my experience
with the K3 NR. I really didn't think it was a problem though. I just
thought I would add my comments because other folks started saying that
they had the same level of audio with the NR on or off. Maybe their NR
is not working....who knows.
