Yes.    The "1200 Baud out" is audio the same as at the speaker (except 
that the level is fixed) and is live on all modes (CW, SSB, AM, FM, 
etc).  On FM this output is usually de-emphasized and squelched.   

The "9600 Baud out" only functions in the FM mode, as it is the raw 
unsquelched, non-de-emphasized output of the FM discriminator only.

A PDF document with all the details on this connector (which is a 
general purpose audio input/output/PTT/squelch connection useful for 
APRS trackers, TNCs, sound card interfaces, phone patches, Echolink 
interfaces, etc)  is located on my website: . 


Look for the file    *MiniDIN6-Packet.pdf *
