Good points Jim, but as a group we are a "lazy sort" and many purchase 
their BNC coax assemblies from those who offer pre-assembled cables.  In 
that case, there is no opportunity to specify the connectors - we have 
to trust that the cable vendors are using quality connectors in the 
cable assemblies that they sell. Unfortunately that may not always be 
the case.

I agree that we are hams and should have some element of technical 
expertise, and the simple matter of putting a BNC connector on a piece 
of RG-58 should not be a problem for us, but the reality is that hams 
are more and more becoming "appliance operators" with little skill in 
how to assemble things like BNC connectors.

I have done my best to get my grandson Josh KJ4NYI interested in 
homebrewing (or at least kit building), and so far the results have been 
successful.  He has built a K1 and a K2, as well as many of the QRPme 
kits, and is currently building a KPA100.  He takes pride in his work 
and does a really good job of it.  I am working with him on 
troubleshooting steps and techniques - progress is OK, he does not yet 
understand all the theory, but at least he is trying to "put it all 
together" which is more than I can say for some of the questions 
presented on the common ham radio reflectors which seem to ask - "I 
don't want to look in the manual, just tell me how to operate this thing".
