AO-85 and Fox-1B/Cliff/D will start the transmitter "hang timer" when
they detect the CTCSS.  The tone must be again detected within 60
seconds in order to reset the hang timer else the downlink transmission
will stop.  By having your tone on your uplink signal all the time, each
time someone keys it resets the hang timer.
