I'm getting ready to send the 9k6 signal to my sound card somehow, so 
this is of interest to me too, even though right now I do 1k2 packet 
with a KAMPlus I picked up as a hamfest bargain. 

The operating manual says on p17: "The FT-847's PKT jack connections 
are optimized for the data transmission and reception speed in use. In 
accordance with industry standards, the signal levels, impedances and 
bandwidths are significantly different on 9600 bps as opposed to 1200 
bps." 

Looking at the schematic in the Technical Supplement, the signals for 
pins 4 and 5 come from *way* different places inside the radio. The 
description for Menu 23 implies that how it's set selects one pin or 
the other for output too. Fortunately that menu setting is apparently 
stored in the channel memory for each channel.
