[VHFcontesting] Looking for audio box 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.
