I took it out of the cabinet and moved it to the workbench during which time 
it cooled off.  When I first turned it on, 80 meters was normal for about a 
minute or so. The antenna trimmer worked as did the calibration signal at 
3.500 and I was able to copy a bunch of CW folks but soon it reverted back 
to the failure mode as described in my earlier email..
