Dear,

I have been reading the wpx/rj rtty rules.

Is there a single band  low power categorie ?


The rules are not very clear : 

V. CATEGORIES   
1 Single Operator : (single band and all bands)
1a : single operator 
1b : low power  : same as 1a  pwr < 150w
1c  : rookie 

2. Multi .....


Is there a   categorie : single band  low power ? 
In the results of past  contests I see only    single band / single operator   
no power level is mentioned .
