[Elecraft] K3 FW3.25 Auto-Notch Filter problem.

[Mike Harris]

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
