[Elecraft] K3 Calibration in EU

[ON4WIX]

Hi all,

I just finished building my K3 and I'm now ready to start the Test and 
Calibration Phase (starting at page 57 in the assembly manual). At this time 
I have 2 questions.

1) I have installed a 2k7 filter in FL3 and a 200Hz filter in FL5. The other 
slots are empty. I assume I have to set the filter width of the unused slots 
to 0 with 0 offset and assign FL3 to transmitting duties in the TX FL menu?

2) The Reference Oscillator Calibration section says to zerobeat a strong 
local AM broadcast signal. What have the EU K3 builders used as a reference?

Thanks very much for taking the time to answer
