[RTTY] Decoder performance on crowded bands

[WW3S]

What I think usually happens is the skimmer cannot tell the difference between who is who.....so since most people now append their CQ message with CQ, it goes like this....
CQ AA5AU AA5AU CQ
and then I answer
DE WW3S WW3S 
ends up looking to the skimmers as 
CQ AA5AU AA5AU CQ DE WW3S WW3S
and I get spotted on Dons run frequency....
just a semi educated guess, from a semi educated man....
