I have used my FT-897 with an hardware TNC (TNC7Multi), and I have no trouble
receiving 9600 bps telemetry from AO-51 and packets from GO-32. My radio was in
PKT mode and I set the PKT Rate menu option to 9600.
It's important to follow the manual and connect to the 9600 bps pin on the Data
connector and not the 1200 bps pin. The 1200 bps signal is the processed audio
after filtering, where as the 9600 bps signal comes right off the radio's
discriminator. The audio filters are too narrow for the 9600 signal.
