Expeditioners that do lots of portable setups have repeatedly preached 
that when anything goes wrong in a radio system to ALWAYS suspect a bad 
piece of coax, and usually a bad or poorly installed connector.

Back in the days when I was doing lots of live recording and sound 
reinforcement gigs, it was mic cables. A standard test was to plug a mic 
into the mixer with the cable(s) to test, listen on headphones with the 
gain up, and "rattle" both ends and the cable itself to expose any 
faults. To test coax cables, I'd do something equivalent with low power 
into a dummy load and watching SWR at the rig.
