[amsat-bb] Signalink Modification for 9600 baud

Hi Christy,

Correct, pin 4 on the 6 pin mini-din to Signalink SPKR pin.
With the IC-9100, for example, it must be set to FMD (FM Data). Looks 
like the FT-847 needs menu #23 (Pkt-Rate) set to 9600.

The cable I'm using is the SL-CAB6PM.  This has all 6 wires connected.  
I was using it with a FT-847 when I had one.  Plugs straight into the 
IC-9100.  Just need to change the Signalink jumper from 5 to 4.

I'm still yet to try TX.  Will get there though :)
