[Elecraft] W2

[David Herring]

Just to wrap up this question for the benefit of anyone else who is interested or may search for this later…

Jack’s response prompted me to go back and take a second look at the schematics for the couplers. Somehow I missed this the first time through, but it would appear that the coupler will provide a short to ground for a DC bias voltage by way of the secondary winding in T1.

So I’m going to take “no” for an answer here. ;-)  I don’t think the HF couplers will pass a DC bias voltage on through like I had hoped.
