Ya' made me go look (again) Mike:
On mine, both auto and manual work, but the manual notch is much deeper than
the automatic notch.
Using the K2's internal metering while invoking the notch listening to a
clean input from a signal generator, I see a 38 dB drop in level using the
automatic notch and a 51 db drop using manual notch.

G'day,
To hopefully settle this, at least for my own case, I reloaded Beta
3r19 and did the following test:
14195kHz SSB, AGC F. S7 signal from my K2. With my line out
setting this gave a -46dB signal displayed in Spectrogram 16.
Applying auto notch reduced this to -87dB or better.
Reloaded Beta 3r25. With the same set up the signals displayed
were -46dB notch off, -72dB notch on.
I conclude that something significant has changed with auto notch.
Regards,
Mike VP8NO
