[Elecraft] KAT100 signal question

[BobConvers at aol.com]

In troubleshooting a relay problem on my KAT100, Gary advised me to check the 
signal /8R, generated by Q3.   I think Q3 may be faulty, since (using a Fluke 
DMM) signal /8R alternates between zero and only 4.99v as the KPA100 is 
cycled between receive and TUNE.   Signal 8R alternates between 7.91v and zero, as 
I would expect.

Before, I disassemble, de-solder, and install a new Q3, however, could 
someone verify that 4.99 v is indeed lower than it should be and Q3 is probably bad. 
  Thanks.
