[RTTY] Decoder performance on crowded bands

I think the CQ on the end serves two purposes. First, if a S&P station tunes across a signal and misses the opening CQ he has no way of telling if this station is calling CQ or just finishing working someone else. The CQ at the end removes that doubt. Second, I think it so a skimmer can find you sooner. Same reason as above.

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.
