You can't monitor 9600 baud through the normal audio channels.  They do not
have enough bandwidth, and have too much filtering.  Many rigs do have
dedicated I/O for the purpose.  Likewise, standard packet/PSK31 interfaces
will also fail due to lack of bandwidth.  You will either need one of the
hardware TNCs which do have 9600 baud capability, or you can work with
programs like MixW which support it.  In either case, you will need direct
connections rather than the usual audio transformers.  If you don't have the
existing capability, it might not be cost/time effective.  Sigh.

I am packet-illiterate. But HRO locally does not have the Yaesu mic cable in
stock to interface any of the West Mountain RigBlaster products I could
purchase for my Yaesu FT-8800.

How else can I attempt to monitor this? HRO is open four more hours today
