[RTTY] Decoder performance on crowded bands

[Don AA5AU]

We have this discussion every year but here goes again. The reason I put a CQ at the end of my CQ message is so that anyone tuning across the end of my CQ message knows I'm calling CQ when they see CQ at the end of the message and they don't have to wait for me to call CQ again to know whether I'm running or S&P. If I send just:
CQ AA5AU AA5AU AA5AU then someone tunes me in toward the latter part of that message the S&P station doesn't know. As a fan of S&P, I greatly appreciate operators who put CQ at the end of their CQ messages.
After years of experimenting, CQ AA5AU AA5AU CQ seems to be the perfect CQ macro for me, especially when I'm SO2R.

Why do RTTY ops even put a "cq" at the end of their cq message?

CW ops never put a CQ at the end (except for a few newbie 
converts from RTTY).  45 Baud RTTY is 60 wpm, a lot faster than 
contest CW, so it's not like we had to wait so long for the call 
sign that we forgot that it was a CQ.

Since RTTY Skimmers are increasingly powerful and popular, and 
are getting confused by the cq at the end, maybe it's time to 
just drop that final cq.
