[RTTY] Response to DX Station

[W3OA]

  I've just watched the CE0Y/I2DMI and 9X0TL videos.  While the multi 
channel decoders are very cool, what surprised me was the length of the 
responses from those who had broken the pileups.  With over 300 
confirmed on RTTY I thought I knew what I was doing.  Maybe not.

When the DX station comes back to me and I'm sure he has my call correct 
I send "599TU" and shut up.  In the videos a lot of the stations 
repeated their own calls, some repeated the DX station's call, and many 
added other "niceties".

Am I missing something?  Is there an advantage to a long response when 
the DX station comes back to you?
