With MON, you hear the slightly delayed audio from the monitor as well 
as your own voice.  This may be perceived by some as a slight echo.

The delay is due to how DSP works.

Tx audio is processed by the DSP (leveled, filtered and equalized), 
converted to a nominal 15 kHz IF, clipped (if compression is on) and 
then sampled, downconverted to audio, filtered again, and passed to the 
speaker or headphones (or, now, LINE OUT :-)

There is some delay associated with all of this processing.  This is 
most likely what you are hearing as a slight echo effect.

If you record MON and then play it back while you are not speaking, 
you'll hear no echo.

If you have the KDVR3 installed, listen to a voice message.  No echo.
