[RTTY] The magic of TU

[Vladimir Sidarau]

OK, the TU message is nice and polite, but there might be another aspect of 
that. For whatever reason in the recent CQ WW I think I have noticed that 
the TU combo breaks through the screen garbage better than anything else. If 
there is a final message from a weak station, his call or my call can be 
completely unreadable in the garbage, let alone other messages like CQ, but 
the TU is clearly visible in most of cases. I can only speculate that it 
might be caused by structure of the 2 characters thus decoded easier than 
others, but I am not an expert in ASCII codes and cannot prove it at all.
Can anybody confirm this observation? Or was it just a considence in my 
case?

Anyway, I'll change my QSL message content from QSL (initially I tought, it 
is larger and therefore more explicit than TU) to TU.

73,

Vlad VE3IAE
