I've seen that happen, Roger. Luckily it was in the shack at the end of 
a long run of 9913. I wouldn't use an N connector unless the center pin 
was captured by the connector body, especially with 9913 which is 
probably the absolute worst choice for cable when using a non-captive 
center conductor.
