21. The Model I could not meet FCC regulations on radio interference due to its plastic case and exterior cables. 22. The main factors were the topography ( set in the Western Maine Mountains ), and the radio interference signal level. 23. Cohen scorns proposals to build future radio observatories on the far side of the Moon to escape terrestrial radio interference . 24. Suitable sites for the SKA telescope must be in unpopulated areas with guaranteed very low levels of human-made radio interference . 25. Many of the scientists said they were worried that rapidly increasing radio interference could hobble astronomy at Arecibo and other radiotelescopes. 26. SKA is a radio telescope and must be based in an area where there is very little man made radio interference . 27. However, the actual range can be limited by radio interferences , high-ocean states and ground conditions in the vicinity of the antennas. 28. In some applications the insulating layers must be grounded, so they cannot build up a charge and arc, causing radio interference . 29. The joint malfunctioned a few weeks ago; the brakes would not release, possibly because of an electrical short or radio interference . 30. The only problems McIlvaine anticipated for the PalmVue concern the paging systems, which may have to be upgraded to avoid radio interference .
