[Elecraft] K2 Low Power Out / Hi Current

Jeremy and all,  the external wattmeter reading has to overcome the 
diode drop in the wattmeter before it will provide deflection.  At low 
power levels it may show no response until the power is great enough for 
the diodes to conduct.
The full scale reading of the wattmeter may be correct, but at low power 
levels there is a certain 'threshold' below which some meters will show 
no power output (regardless of the range).

I am glad to hear that you now have the bandpass filters peaked.
