I am also concerned about your statement about the "right" level
drive to the XV144. In the XV144 there is no provision to switch in
any fixed attenuation.
It's on the control board in the form of relay K7 and three 160 ohm
resistors.
Now that I've studied the schematic a bit more, I realize it's the
resistors switched in and out by JP3 and JP4, and the gain stage Q6,
that can be bypassed or not, as set by JP5 and JP6.
For the K3, instructions are to bypass the resistors, activate the gain
stage, and set the K3 for 1mW.
So I've got my answer, I think.
