Hello,
I've traced the 2.8 kHz filter response with Mike's

I've a *.bmp file (~825 kB) or a *.txt file (~2kB).
How can i show this unexplained (for me!) anomaly?
I don't find a file upload procedure for this group.
Thank you for your help.

The anomaly is not really an anomaly, it is just the other side of the down
conversion oscillator. For a filter to pass an SSB audio signal the passband
needs to go down to 300Hz or so. For this to happen the attenuation for 0Hz
and image frequencies can't be that far down. That is all it is

Mike,
Thank you for the explanation; i understand now that this
false anomaly is present with the 2k7 and 2k8 filters.
May i abuse of your knowledge to explain to me the following
behavior
:
During receive, the 2k7 and 2k8 filter seem to give a ~ 300 Hz at -10dB
frequency; it's ok for my use;
As I understand it, the K3 switches to a different input bandpass filter
at 10.000 MHz which I believe is the source of the artifact. You will
get a cleaner response with K3 Filter if the test signal is not at 10 MHz.
That's unfortunate, as it's easy to find a clean strong 10 MHz reference
I am not sure that VFO CTS is working properly in 2.78. One complete
revolution of the VFO knob changes the frequency 2KHz in CW mode for
me. This appears to be the VFO CTS value of 200. However, I see no
difference if I have the value at 100, 200, or 400. Am I missing
something here?
I have found that a change to VFO CTS does not take effect until power
is cycled - try that.
