Yes, SO-50 requires a 67 Hz PL tone.  Note that the satellite receiver is 
turned on by a 74 Hz PL tone and stays on for 10 minutes.  After turning it 
on, if it is not already on, switch back to the 67 Hz tone to talk.  Be 
aware that if you are talking through the bird and no longer hear the 
downlink, the 10 minutes since the last time it was activated may have 
expired.  If so, just turn it on again.
