[Mikrotik] SR9 Scan

[ccrum]

I have set up some 900 MHz APs running 5 MHz channels on 3.9. Wen I scan 
from my CPE, also running 3.9, I get 3 of each AP on 3 different 2.4 
channels. The strongest is always the channel I'm supposed to be on, but 
ther eare still 2 others listed. Does anyone know why?
