Just a wee little bit of power.

 

also might want to check out "XERF" the station with twice the power, made by the same group of engineers essentially doubled up everything.

 

Growing up in Texas we had an assortment of 'border blaster' X stations. http://en.wikipedia.org/wiki/XHRF-FM

The most RF power I've every seen in person was at NWC in OZ.
