Then I'm assuming that you'd agree that a typical ham-installed connector 
should probably have the center pin soldered?

  Chuck,  I work for a National Telecom company here in Canada
  and we crimp everything used on DS-3 (BNC)  and above. For the center pin
  you need a 12 point circular crimper and for the sleeve you need a good
  quality hex crimper such as Tyco etc. These two items can run you several 
hundred dollars each.
  The SMB crimper that we use costs around $1100.00

  I've probably done a few thousand of them and never had a failure.
  So the trick is to have good tools and know the proper way of installing the 
  connector.

  Seems to me that someone once mentioned that you must use crimp connectors on 
aircraft...???
  ....not sure if that is true....

    To reduce PIM, the center conductor should be soldered. Whether there is a 
practical (measurable) difference would depend on how well the crimp was done, 
vs solder.

    From an Amphenol paper:
    "Cable Attachment: Mechanical stability of the cable/connector junction is 
of utmost importance. Small movements caused by flexing can be translated into 
significant PIM. Center conductors should be soldered, not crimped."
