[Elecraft] K1 problem

[Randy Moore]

Thanks for suggestions from several, both on and off the list.

With an ohm-meter, I checked that K2, K4 and K6 were in the correct state
with 20 selected, and they were.  I did a triple visual check of all the
20m-specific component solder joints on the filter board and they looked
fine.  But I re-heated all those joints anyway and voila!  It works again!!
So I guess one of those joints was marginal.  We'll see if this occurs
again. 

By the way, I'm loving the K1, but not quite as much as my K2!
