Thanks.  Since just about all 1200 baud packet uses pre-emphasis on 
the TX side, I wonder what is the degradation in packet success rate, 
if any, by not using de-emphasis on the RX side.  I guess the TNC 
could provide de-emphasis.  I have always thought that perhaps 1200 
baud packet should be run flat.
