[RTTY] Decoder performance on crowded bands

I even put a CQ at the end of my TU message. TU VE7CC CQ

Dave, 

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.
