Thanks to all who responded. Checked and realigned all connectors, no
apparent errors, all male pins in place, connectors firmly seated.
Removed KRX3 and SUBIN/OUT module, reinstalled and reconnected. Similar
advice received both from group and from Elecraft support.

Solder lug/solder tag/tag washer all the same thing. :-)
Perhaps instead of dry joint I should have said "broken joint". The bond
between the solder lug and the connecting wire had become broken,
resulting in the effect of a dry joint. This could have been caused by
someone being over

"Two countries separated by a common language." I believe "tag washer"
is a "solder lug" on our side of the Atlantic. I think Alan might mean
the screw connection on that lug becoming intermittent due to oxidation
and/or inadequate tightening. Generally speaking, cold solder joints

I had this happen with the 2M module, too. What I do now with these is try to
support the little teflon insulator in the socket from the rear with a small
flat-blade screwdriver — at least the ones I get to that way.
Took a while to figure out what the problem was, since everything looks

Must underscore what Don said. Busted BNC connector/coax wiring is so
very common. If they were hand-done with soldering iron and NOT RG400
coax (teflon, won't melt) or were not crimped with specific tool
required for the specific connector and specific coax, they are more
likely to go bad over

I have a K3 approx 8 years old. Fully equipped with subrx, 100W PA, antenna

When I connect the subrx, the main rx sometimes loses signal and at the same
time power out goes to zero.
Looking at the diagrams, I suspect there is an intermittent contact problem
