[Elecraft] K1-4 4 band version gone?

[Don Wilhelm]

I am aware of the "rubber band trick", but I find no difficulty at all 
in plugging the KAT1 even with loose standoffs.
First place the standoffs so they are close to the holes in the board.
Next (and most important) put the long screws through the KAT1 board - 
hold them down with your fingers or thumbs.
Now eyeball the top of the standoffs with the end of the screws and 
insert the screws a bit into the standoffs.
Since the screws contact the standoffs before the connector pins come 
close to their mates, you can now align the connectors and push them home.
Wiggle the screws a little bit to get them to drop into the holes on the 
KFL1 board and tighten them - job done.
