Assuming the transmitter still works on
40, and the RX ANT switch is in the right position, the only thing
that seems to make sense is that the control signal for the RX ANT
relay is somehow in the wrong state on 40.
What happens if you hook the antenna to
the RX antenna jack?

After a couple of days complaining about lousy conditions on

big gun stations, but about s1/s2 level. Turned on my KX2 and
the band was full of strong signals. K3S is still great on 80
Any ideas on what is causing this monoband deafness?
i will probably ship it back to Elecraft when things get back to
normal. My tech skills were never much and poor vision does not
