With your ears like the manual suggested. ;o)

> Can I use analog multimeter for best result? How?

Yes, you can. Connect an analog multimeter on the AF output and adjust R1 respectively R2
on the KAF2 module. A maximal signal must be your goal.

An alternative choice is to use the (freeware) software named "Spectrogram". You will find
the software via the Elecraft Homepage on Tom Hammond's (N0SS) or also on my website.
Connect a computer with a sound card inside on the AF output. Now you can adjust R1
respectively R2 on the KAF2 module exactly. I use the software also to match the in the
manual suggested birdie at 7000 kHz with my CW sidetone.

Alex,

Use your DVM to measure the voltage at the wiper of the reflected
potentiometer - adjust for a minimum.  If the minimum is high, then check
your work - the diode orientation, the winding of the bifilar transformer,
and other components in the circuit (look at the schematic to identify the
related components).

73,
Don W3FPR
