[cma-l] Fwd: Re: Warm weather hazard

[Mike Davison]

I second Ian's warning as we had a problem the other day. During the 
early hours of monday morning there was a sudden drop in modulation 
level and a definite reduction in audio quality of the output of the 
station. Checking the 1.5GHz link output cleared the studio of any 
problem so a trip to the transmitter site was necessary fearing the 
worst of a major item failure. Whilst monitoring the relative components 
of the VHF output and swinging out the wall mounted cabinet everything 
returned to normal so we concluded it was a connection problem and 
checking around it was found the baseband feed from the link receiver to 
transmitter had an un-locked BNC plug which was duly secured. We can 
only guess that expansion/contraction of the loose plug had eventually 
produced the intermittency but it was a sobering experience.
