[RTTY] WHY put CQ at the end?

[David G3YYD]

In the recent CQWPXRTTY no skimmer spotted me... I suspect it is because my contest callsign is so short. 

My CQ call was: CQ M7T M7T CQ M7T

I find that there are still a lot of people around who do not realise that England has these minimum length callsigns even though they have been in use for more than a decade. So I have to send the M7T three times. The CQ in the latter half of the call is in case someone tunes in the signal and does not get the initial CQ and the M7T at the end is to avoid someone just hearing a CQ with no following callsign.
