[Elecraft] K2: Debugging low transmit power

[Don Wilhelm]

  Brian,

Even though Owen's outward symptoms are similar to yours, the failure 
point is likely quite different.
That is why Transmit Signal Tracing is important.  There are 5 active 
devices in the transmit chain as well as the bandpass and low pass 
filters, and the oscillators (VFO and BFO) can cause low output as 
well.  The only way to know which one is the culprit is to move forward 
with the transmit signal tracing.  There is no one single answer, each 
case is different.

Every solder connection and each toroid lead is a potential failure 
point, not to mention those components that jump out of the correct 
holes and end up in the wrong places just before soldering.
