Jim,
In reverse order, you will need to change the DSP-2232 modem to the "1200 baud VHF." Modem 12 if you are using radio port 1, Modem 22 if you are using radio port 2.
Note that there are two transmitters which alternate, several bursts from A, then B. Mike, DK3WN, estimates the center frequency for COMM A = 437.3655 MHz and COMM B = 437.3664 MHz. Also, there is a slight frequency drift as the satellite cycles from eclipse to sunlight.
Finally, I have found that the data bursts are not quite as regular as advertised. Sometimes they come within seconds, usually every minute or so, and occasionally there may be only one or two in a 10 minute period.
