[Elecraft] K2 Power Problem

[Don Wilhelm]

Larry,

It is difficult to judge what the output should be with the N-gen - 
there are just too many variables to draw any valid conclusions from 
that information.

I suggest that you back up a bit and align the bandpass filters in 
transmit at a power level of 1 to 2 watts.  Use the band order specified 
in the manual.

Once you have done that, check the maximum transmit power available on 
all bands.  If any bands are low AND draw excessive current, then check 
the low pass filter for that band.

Once you have good output power on all bands, then you can evaluate the 
receive knowing that the bandpass and the lowpass filters are OK.  (Do 
NOT readjust the bandpass - the transmit peaking is the final adjustment 
and if it is peaked for transmit, it will also be peaked for the receive 
condition).
I know this is a bit 'backwards' from the manual, but at the point where 
you are stuck, this is the best path forward.
