[Elecraft] KPA100 SO-239 Help

[Jack Smith]

I've found the same problem with two batches of Teflon insulated, single 
hole mount SO-239 connectors manufactured in China and purchased from RF 
Connection. The center pin spins within the Teflon bushing and unless 
the user is extremely careful when connecting a PL-259, the wire 
connected to the center conductor will break off.

I returned one batch and received a second batch that were supposed to 
be correct and found the same problem. I rejected those as well.

I agree that a connector with this problem should not be used - too 
great a risk of damage to the internal wiring.
