I'm building a K2 kit and I have a problem.  I'm starting the Alignment 
and Test, Part III on page 77-78.   I have no rf out.  I have followed 
the rf through the tx chain and have a good signal at (RF board) Q5 
collector (800mv P-P) using a 400Mhz scope.  I have a signal on Q6 base, 
but nothing on the collector.  The DC voltage (in TX) at Q6 is 12.0 
Collector, 1.8VDC base and 0 on emitter.  I don't see anything wrong DC 
wise, is it likley that Q6 is bad?  What else should I look for?  With 
the radio off the R at Q6 emitter to ground is 1.8ohms, that looks 
normal, so I don't have any current flow in Q6, it looks like.

Thanks,
