You are probably using Rx EQ and have your preferred
sidetone pitch peaked to something more than 0 dB. RxEQ
is not available at these two narrow bandwidths.
Note: It seems that many people believe that the Rx EQ is
an *additional* filter cascaded with the normal DSP
filter. It is not.
In general, if you want to apply RxEQ shaping in CW mode,
I recommend that you set your preferred sidetone pitch to
0 dB and use cuts on either side, or for whatever shaping
you prefer, and not use any peaking above 0 dB. That will
avoid this problem.
