Thanks Mick
I actually think the signal is dropping off causing the RED on the AGC%...if you remove the feed in the engineering page this is what happens, so it looks like the signal is intermittent, although its stays as GOOD on the page 4, but all the AGC values are on the problems page!!!
The thing is the values are close to what they should be, but appear to flutter into the bad values then back to the good ???
