OK, this is what I did.

I set KPA3 to 'PAio nor'.  I then started at the beginning and did the 
Synthesizer calibration, then set the reference oscillator to RWM on 
9996 kHz.  I then ran the 5W calibration and then, after enabling the PA 
again, the 50W calibration.
The output seems much better now but i am going to have to get it on a 
decent calibrated wattmeter to be certain of actual output power.  TXGN 
HP Pr80 is now at 32, in line with other postings.
The question is, how did it change?  I had set all of this initially of 
course in the build.
In the manual, once you have finished the calibrations, it says to turn 
off TECH MD.  Could it have something to do with this?  I had not turned 
it off as I like to see things like PA temp etc and I believe you have 
to have it on to see the extended displays.
Sorry if I seem thick, I am just trying to get my head around this.
