Look at pictures, the TX cw signal looks very wide with distortion. Looks like this in 6, 10 and 17m. Can anyone explain why it looks like this? 73 Jonas SA7AKE image

    One thing to be careful of...  I don't know how accurate this display is in showing transmitter spurs.  If you turn on FDX (full duplex) and transmit into a dummy load, you can see how the radio actually hears the transmitted signal.  On my 6400, I don't see any spurs at all even though I have a very similar display to yours when not in FDX.

    Yes the monitored transmit can look really dirty.  Best to use the dummy load method and full duplex.
