[Elecraft] KPA100 SO-239 Help

[Don Wilhelm]

  dw,

No worries -- There are two wires connected to the inside of the KPA100 
SO-239.  Yes, one goes straight out the back of the center pin, but the 
other is soldered at right angles to it - the wire soldered at right 
angles will stabilize any tendency for the center pin to turn after it 
is soldered..

I have seen and used many SO-239 connectors with a center pin that will 
rotate.  This is not a problem under normal conditions.  One simply 
slides the center pin of the PL-259 in, but does not turn the coax more 
than 1/8 turn in the process.  Yes, the shield connection is turned to 
tighten the connector, but not the center conductor.
