I have always thought of "MCW" as an AM signal - used so that receivers
with only AM capability could copy them.
OTOH, if a SSB signal with sufficient carrier and opposite sideband

just as good as a CW signal. Unfortunat

At one time a lot of fellows tried to work all the serial numbers for a

The W2 is great, but of marginal use for someone who has a rig with an ATU
built in.
Indeed, one of the reoccurring mistakes Hams make is to put the external W2
between the rig and the antenna and then wonder why it shows a high SWR when
the internal ATU reports 1:1.

Most modern commercial transceivers effectively generate CW as SSS MCW.
I think the K3 does it at about 15kHz or less, which is within the
