FW 4.51 CWT ( Another Perspective)

All you have to do to get good CWT copy is to turn the CWT Threshold to about 7.

I get good copy with CWT with the NB on of off at this setting.

I have the AGC threshold set to 14 and the SLP set to 000.

I have run the SLP up to a setting of 10 and still get good CWT print.

I am not sure we have a problem with CWT at all. Just the right setting of CWT threshold.

As far as the Auto Notch is concerned, I like the present reiteration of the Auto Notch.. It might be a second slower in notching, but it does notch. The reason I like it that it does work at my settings, and is not as aggressive which means less distortion of the receive audio when engaged. Less of the hollow sound or watery sound when engaged.

>From my perspective, I don't see the need for changes.

But understand others points of view.

So, I actually liek the less agressive auto notch.

Re: FW 4.51 CWT ( Another Perspective)

There is definitely an issue with cwt function in the latest beta firmware.
A clearly audible but weak cw signal failed to pulse the indicator properly
at manual 1.
Usually the noise is pulsing it around 1-3, but that is no longer the case.
It needs fixing. I noticed it quite a while ago, but kept quiet to see if
anyone
else picked it up. It is no longer sensitive to other than strong signals.

Re: FW 4.51 CWT ( Another Perspective)

Odd, because CWT is working just fine on my K3 with the 4.51 FW. In
fact, I just checked it and found that it was functioning properly. One
of the dangers of beta software, I guess- things may not work quite
right for everyone.

That's confirmed here too. I thought I'd (yet again) done something wrong
so it's nice to see someone else make the same observation.

On a weak yet copyable signal (some arctic flutter), there was no CWT
response (and therefore no decoding either). Altering THR or SLP did not
make any significant change. Setting "auto" didn't help; my normal 1-3
still had trouble. Dual passband mode didn't affect it either.

CWT worked GREAT in 4.48.

Ah-yup, that's the cost of beta-ware; two steps up, one sideways. :-) I
know you'll get a handle on it guys.
