[NLRS] Bad BNC Jacks???

[Scott]

It appears I've been bitten by another bad BNC jack.  This time on my 
W1GHZ 222 transverter.  It exhibits the same problem as the one I 
replaced on my DEMI 10 GHz unit.  If I wiggle the coax connector body 
side to side, the transverter output power drops to a low level.  This 
makes me think there is some issue making contact between center pins.  
Are the center pin diameters different size between 50 ohm and 75 ohm 
connectors?  I would suspect they would be.  I am about ready to give up 
on BNC connctors.  I suppose N connectors would be the logical choice?  
Anybody else run into this problem?  Input?
