[CQ-Contest] WPX categories, ie: TS category

[N6CW at aol.com]

Guys,

I submitted my WPX CW score as SOAB (TS) HP because I saw other scores 
claimed under this category (assuming it meant Tribander/single element), and 
because this is what I operated. The robot rejected my log as not being submitted in 
a valid category, and listed a bunch of categories that did not include TS. 
Since a bunch of logs have been submitted in the TS category, even single band, 
is this a valid choice or not? 

I chucked my CQ magazine with the rules, so I really don't know the answer.

Any help?
