1. In radio applications, intermodulation may be measured as adjacent channel  power ratio. 2. AM stations are never assigned adjacent channels  in the same service area. 3. WPRB and WKTU operate on adjacent channels  and are only 51 miles apart. 4. External levees can confine adjacent channel  belts to form levee-confined systems. 5. Emissions on further adjacent channels  must be reduced to almost zero. 6. Across an adjacent channel  is Shell Oil's largest U . S . refinery. 7. This prevents the simple concatenation of adjacent channels  to create a single broader channel. 8. Currently, imposing a second adjacent channel  restriction would impact less than 10 LPFM stations. 9. With little adjacent channel  interference, KOMA had a tremendous reach with its directional antenna array. 10. The advantage with this method is that it will capture more packets because adjacent channels  overlap.
