If your CW filter shows multiple peaks with the bandwidth at 1000 Hz and

Andrew,
There isn't much space for a serious noise blanker in the KX1. You
might be able to make a module that fits in the same place as the KXB30
or KXB3080, but blankers take a lot of parts, so it would have to be
all SMT. There are very specific height constraints on any components
used
Wouldn't a K1 be a better choice for someone who wants a small CW only
rig as their main rig but needs NB? Or maybe a K2?
Funny thing is, where I live I have no need for a noise blanker.
