All the adjustments look to be within spec. I had a look at Q3007 (UPC1677C) I compared the readings against Q3011 and I am getting nothing on pin 5 of Q3007. I am getting just over 4V on the KEY line, pin 8.
Perhaps Q3007 is bad. Isn't this the same predriver ICOM used in the 746 and 756 series radios? Lots of them went south. I don't think you can get these anymore.
