I saw that in their latest on-line catalogue, Jim -- but I'm cheap!  I
found a September 1992 QST article (not initially found through the on-line
index) that discussed using an earlier Radio Shack RX, but it looked like a
lot of work -- had to put a shield box around the receiver, because it was
unshielded, and build an attenuator for the input to defeat the AGC and
prevent it from evening out the nulls when you get close.
