Re: K3 FW3.25 Auto-Notch Filter problem.

Yes, I am finding the same here - AGH !

The Manual notch is fine, however, although there is a slight
notching action in Auto it is virtually useless.

Some'at wrong with the DSP code...

Re: K3 FW3.25 Auto-Notch Filter problem.

Interesting.. Mine seems to be working as it did before. I just tied
it on a few AM stations near 40. Got in the area in LSB got it setup
with the carrier in my window hit the button and poof gone.

I then found another tone that seemed to be drifting back and forth a
little bit and hit the auto notch on that. It seemed to notch it but
was following it a bit slowly so it was just off of it every so often
but it was updating and keeping things quieter.

I also QSYed quickly when the notch was doing its thing and you hear the
tone come back for a short bit then you hear the filter slide over and
keep the carrier covered up.

Are you sure you're in a mode that supports the auto notch? Its not
supported in DATA or CW.

Re: K3 FW3.25 Auto-Notch Filter problem.

As you say Brett ... Interesting.
I will try it again, and look for any new Menu settings that may have crept in unnoticed.
This was on SSB, a mode which I use almost 100% of the time.

Tried it again using my XG2 as a signal source, and it's working OK.

Gremlins at work !

G'day,

Broken here also. I have a multi tone QRM (digital junk) signal at
about 14213kHz and previously auto notch would take them all out in
a couple of seconds, now it doesn't touch them.

I tried notching an Ethernet signal at 14030kHz in SSB mode and only
when it was single signal, BW reduced to 150Hz did it try feebly to
do anything. More than one signal and it doesn't bother.

Manual notch is OK but as others have suggested, it could be
sharper.

All this observed on Spectrogram 16.

Regards,

Mike VP8NO

I'll add to the list as well. On WWV in SSB mode Auto notch will not mute/find the tones. Manual mode works fine. Bet it will be fixed in short order!
