[CQ-Contest] looking for article

[dave at egh.com]

        About 15 years ago, a W5 (or WA5) wrote an article which
        described a two-radio audio box, based on the Radio Shack
        "Stereo Audio Selector" box, part no. 42-2110.  This box
        has 3 push buttons on front and 8 audio plugs on the back.

        Does anyone have this article hanging around?  I googled quite
        a few combinations of words that might describe this, but
        could not find it on the internet.

        Thanks.
