[Elecraft] Is this normal behavior (CW filter or BFO setup)

[Andreas Hofmann]

Hi,

I just finished the A2B mods and don't recall this happening before. A
CW signal (CW normal, FL1, AF OFF, AGC ON, PRE ON) seems to come back
after I tune the VFO into its 0 Hz tone...  Example:

Tuning down...
1. 7,061.28 CW signal appears, very high AF frequency
2. 7,060.12 signal is in middle of passband (used SPOT to zero beat)
3. 7,059.50 audio signal is at 0 Hz
4. 7,059.39 audio signal starts to be readable again
5. 7,058.95 audio signal disappears

On frequency 4 and 5, I did not expect the signal to be audible.  This
makes it very difficult to tune into the right frequency. Something's
gotta be wrong here...  I did the filter setup using spectrogram.

Only FL1 without AF seems to be wide enough to make this issue appear.


Any help is appreciated.
