Got lots of response for which I most appreciate.
I tried all the obvious things. Processor reset, etc. 
When this occurred I was sitting here listening to Dodger baseball on 
1150 AM... I had worked some PSK31 an hour or so earlier, but like 
most I limit my power to 35 watts or so in that mode.
Consensus here would indicate a bad PA transistor or something nearby.
I intend to get it off to Ten-Tec on Monday, so I will not know 
anything for a week or so.
As requested by several, I will advise as to the findings and fix.
I am going to ask them to check out the SWR thing too. I get more 
then 1.0:0 readings on the higher frequencies even when connected to 
a dummy load and with the SWR meter on the 989C tuner indicating a 
"one-to-one". I have always been told that you should rely first on 
the rigs SWR meter as opposed to something further down the feedline.
