[Elecraft] K60XV Alignment & Test Questions

[Don Wilhelm]

Ken,

The normal procedure uses receive to peak the bandpass filter 
approximately correct.  Then that is followed by using transmit to 
refine that peak - the fact remains that one can observe the real peak 
better by watching the transmitted output power than by listening with 
the ears.

So, you did not find a real peak on receive - the result is that the 
bandpass was not tuned close to optimum when you did the transmit 
adjustment.  No problem, but you can observe the peak better at 2 watts 
than at 15 watts, so as the power increases, just exit TUNE and enter it 
again so the power again levels out to 2 watts, tune for a somewhat 
higher power, and if it goes to more than 5 watts, exit and re-enter 
tune again.  Keep doing that until you find the actual peak within the 2 
to 5 watt range, and you are done.

BTW, you may want to peak up the inductors for 40 meters before 
adjusting the caps for 60 meters.

If you want me to set the power output to 2 watts then I assume I should tune to get about that, shouldn't I?  What do you really want me to do here?
