[Elecraft] [K3] DC Power cable

[Don Wilhelm]

Brett,

You are correct, I read the wrong item on the data sheet.
But still, there are two of them on the K3 cable, and I just tested a 
pair.  It took oveer 8 pounds of weight to dislodge the connection.   
The weight of a fully loaded K3 is 8.5 pounds, so you could not quite 
hold the K3 up with the power cord, but the basic K3/10 should be able 
to dangle on the power cord without breaking the connection (but, I am 
certainly not going to try that with MY K3 :-) ).

73,
Don W3FPR
