[Elecraft] scopeing filters for eventual diversity receive.

[Dave, G4AON]

Inject a clean signal to the K3, around S5 - S7 in level, go into the 
CONFIG menu, adjust the filter offset (FLx FRQ) by rotating the main 
tuning knob until the signal drops one S point then adjust it to the 
other side until it again drops one S point. Set the offset to the 
middle of the two extremes.

My 400 Hz 8 pole filter appeared to have more insertion loss than my 250 
Hz 8 pole, setting the offset solved the apparent additional insertion 
loss. My settings are -0.07 for the 400 Hz and -0.05 for the 250 Hz.

How are you testing for offset? Sounds like I should check the offset on my
5 and 8 pole filters.
