[Elecraft] KX3 Roofing Filter Question

[Mark Petiford]

 Re:  "If you do choose the roofing filter, be certain you do the calibration 
if it is a kit."


Don,

My kit build KX3 instruction manual says that I don't have to do the calibration if I ordered the filters WITH my KX3 kit:

"If you received the optional KXFL3 filter with your kit, you do not need to perform theReceiver Sideband alignment procedure referenced in the Owner’s manual and describedin detail in the KXFL3 option manual. That procedure was done for you at the factory."

That was back in 2013, so maybe things have changed.
