I've found that  hams are notorious for plugging in a multi pin 
connector and not securing the connector to be tight with the provided 
thumb screws.   The "I'll do it later, but I've got to get it on the air 
now" seems to always take precedence .     The connectors will wiggle 
and back out, often leaving an intermittent connection.

Likewise with PL-259 connectors.  Finger tight is simply not good enough 
for a reliable RF connection.  I use a pair of 4" Channel lock pliers to 
snug the PL-259 connectors.   And I solved many RFI issues for others 
just by tightening the PL-259's in the path.
