Future challenges for radio astronomy

The challenge of maintaining quiet skies for radio astronomy continues to evolve rapidly, as it has done for the past 50 or more years. Increased emissions from electronics devices, increased power, ready embedding of digital and wireless electronics, and the increased power and frequency agility of many transmitters combine to make the successful scientific operation of any radio astronomy telescope challenging. This is compounded by the increasing desire to observe outside of the radio astronomy protected bands, e.g. to perform broadband pulsar observations, or to observe redshifted HI.
