However, I agree with Frank that you could easily make one (probably much
cheaper, too) from parts available at RS.

"Make one." OK Stinger, talk to me here. How could I easily make one. I
know I don't want to get the Rat Shack troops plugging and messin' with my
receiver, then I'd have to force em' to send it back and *tune it up.* ;-)

Give me an idea what you're talking about here.
