The way I handle it is to use the channel-hopping function.
Adding an asterisk (*) at the start of a label designates a channel-hopping
memory (pg. 40).

Just for your information. Because I was concerned about metal parts being
attracted to the speaker through the chassis holes in the KX3, I applied a

Not so at all - whilst the low level SSB generated by the K3's DSP may
be close to theoretically perfect, intermodulation products produced by
the K3's IPA and final amplifier stages are present in quantity and are
the limiting factor.

So I think what you are telling me is that the IPA is after the DSP and
