[Elecraft] Simulated stereo

[Victor Rosenthal 4X6GP]

The K3 (and I think the KX3 and K4) has a simulated stereo function 
which allows you delay the audio to one channel slightly, which makes 
signals seem to stand out from the noise. I believe that the radios 
newer than the K3 also have the ability to create stereo separation by 
pitch, which helps in picking out CW signals in QRM.

My question is: is there some kind of device that you can get that will 
take the monaural audio from a non-Elecraft radio or a K2 and produce 
similar effects?
