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

All:

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
