Building the instrument required solving a host of engineering problems, ranging from dealing with a remote, barely accessible site, shielding the dish from radio frequency interference that would drown out the signals from cosmic objects, and developing a first - of - its - kind method to pull a portion of the spherical dish into a gradually moving paraboloid to aim at and track astronomical targets as Earth rotates.

For wireless speakers, we also test range, connection stability, and interference in areas with a lot of radio frequency interference (i.e. the Digital Trends offices). (digitaltrends.com)
One other thing you might check is for radio frequency interference to the TPMS from a Bluetooth - equipped device in use in the vehicle. (mechanics.stackexchange.com)
