This has also been my experience lately, when working SO-50 passes
with a true full-duplex-capable radio at home (IC-2720H mobile radio -
desense issues don't let me work full-duplex on my IC-W32A).  I tried to
send the 74.4 Hz tone during a pass, trying to restart the timer so I
wouldn't need to worry about it toward the end of the pass, but it didn't
seem to work.  Once SO-50's downlink stopped, I could restart it with the
74.4 Hz tone.

Thanks for all the comments on this thread.  73 from the hot desert.....
