I am ready to interface my FCC-1 to the BITX20....Where do I
take the signal from ? From the DDS pads or somewhere else ?
Maybe from top of R27 ?

The one I have that I'm testing is hooked across the DDS pads and
it
seems to work fine.

One possible disadvantage of hooking on the DDS pads is the frequency
tends to vary a little as the wires are moved. That makes sense as
the capacitance will vary slightly as the wires are moved. The wires
should be routed so they can't move. For better frequency stability
the top of R27 might be a better spot.
