KWM2s had wired in open frame relays, and only the usual ham
bands 3.4-3.6-3.8-4, 7.0-7.2-7.4, 14.0-14.2-14.4, 14.8-15.0,
21.0-21.2-21.4-21.6 and 3, 200KHz chunks of the 10M band.

The KWM2A had the above bands, plus an equal number in the same ranges
that could be any frequencies you want. The KWM2A also had plug in
relays, to ease replacement, but the replacements are becoming rather
rare due to the high impedance HV windings.

In later times there was a retrofit kit for the KWM2 that added the
plugin relays, and the extra band segments. There were also a variety
of noise blanker, Q-multiplier, external VFO, and other modification
kits once available. It is an extremely well documented radio.

It is a very nice radio. I like mine.

What are the differences between the KWM-2 and the -2A?

Was there a -2B?

Thanks...
