Default Crimp, Clamp or Solder?

I am new in ham radio and want to get set up to make the coax assemblies
I will inevitably be needing in the future. I am planing on using only
LMR style coax 240, 400, 600 and maybe some 900 if I get into the 1.2ghz
stuff. So is it better to use the crimp, clamp or solder on
connectors. In the case of the center conductor, there are some where
that is solder and the outer is crimp or clamp so is crimp and or clamp
ok for the outer conductor and solder better for the inner? I welcome
all points of view on this. Thanks for you input.


USA DOD and NASA [DOD STD 454 et al] specifications insist that both a
secure and stable mechanical connection, crimp or clamp, be used for
strength, temperature and fatigue stability; and, that solder or weld be
used, occassion appropriate, for electrical connectivity.

In the typical amateur usage that would include a strain relief [crimp
or clamp] for those connections where a mechanical stress [bend or
weight] and solder.
