[Elecraft] loss of RX sensitivity

[Don Wilhelm]

Drew and all,

I beg to differ, unless you meant something different than I read.
The threads on a PL-259 connector are the only thing that connects the 
coax shield to the SO-239 jack.

That is why hand tightening of PL-259 connectors is not sufficient.  Use 
pliers to snug them up just a bit more to assure a good connection.

BNC and N connectors do not have a similar requirement.  They will make 
positive contact without being tightened.
