[amsat-bb] Decoding 9600 Baud Satellites With Yaesu 991a

My Yaesu FT-991a seems to have difficulty decoding certain 9600 baud
satellites. I've been able to decode GO-32 KISS frames, but have not
been able to decode other birds such as LO-74 which tend to transmit
shorter bursts compared to GO-32.
I'm not sure if this can be attributed to the course Doppler tuning that
occurs when using HRD's Satellite Tracking program or possibly a modem
parameter that needs to be set.
I've used UZ7HO's Soundmodem as well as an SCS PTC-III and oddly enough,
the SCS modem decodes GO-32 without a problem, but I haven't been able
to do so with the Soundmodem.
Any ideas? Thanks
