That reminds me of "The Negative Frequency Effect"  If you reverse the TX crystal in its holder you generate negative frequency.  When operating in the negative mode you can put your ear to the mic and listen in on what the listeners are doing.  This also works with TV by looking into the camera lens and watching all the viewers. ;)
