[Elecraft] KX3 and the Sigmalink USB

[Terry Basom]

The SLMODKX3 jumper module for using the Signalink USB with a KX3 or KX2,
has a DC blocking capacitor built in.

Can anyone tell me where it is in the circuit and a value? It eliminates
turning off the mike bias in the menu when using the Signalink USB. I am
just using jumpers and would like to put in the capacitor to eliminate
having to turn off mike bias and having to remember to turn it back on.
