Example:
Applications for this feature include tape recording all repeater conversations,
in which case, the activity count would be set to zero. However, if a taped
message is to be played every 5th usage of the repeater, set the activity
counter/timer to 4.
The three related Select Repeater Activity-Triggered Macros commands allow
the programmer to execute macros based on repeater activity. For example, a
bulletin may be sent a few minutes after the last activity of the repeater. Since
the repeater was recently used, it is likely an audience still exists to hear the
message. Of course, the bulletin would be too repetitious to send every time
the repeater is used. In this light, the activity counter/ timer allows the
programmer to select how often to execute the macro.
The Repeater Start-of-Activity Macro is executed when a fresh key-up occurs.
This event starts an "activity cycle" which ends a certain time after the tail
finishes. If activity occurs before the activity counter/timer expires, the activity
cycle is simply extended. When the activity counter/timer finally expires, the
Repeater Post-Activity Macro is executed. The activity counter/timer, which
watches the number of activity cycles, is programmable in duration from 0–9.9
minutes and from 0–9 events.
Once the activity cycle has been completed, the start-of-activity macro is again
"armed" and ready to execute at the next key-up activity. This is true regardless
of whether the last repeater post-activity macro was actually executed (it may
have been waiting for the proper activity count).
Note: The Repeater Activity Counter/Timer starts when the dropout message is
sent.
