The 180mW cards have better RX levels then the Orinocos as we are not
using the Prism ref design, the RF sub system is better then others
Prism cards on the market.

But this would be a good test to see what happens.  Hmm just to make
sure there is only one card in the AP-1000 correct? Some times if there
are two cards there is not enough power for the 180mW card it all
depends on which AP-1000 you have no two seem to be alike :)
