You've answered the question. Keep it short. Just announcing that
you're listening on a repeater takes a few seconds. Many CQ calls can
take a full 30 seconds or more..! Well the ones I hear can, anyway..!


I do suppose a lot of it has to do with what is common practice in each
area. Some repeater crowds are more formal, whereas some are less formal,
and will allow more "variety". CQ is rarely heard on repeaters or simplex
for that matter (on UHF and VHF); but when it does occur, no one has any
issues.
