According to the NRAO, iRobot's wireless beacons could potentially interfere with sensitive radio telescopes it uses to study the stars. In this case, iRobot wants its lawn mowers to operate at frequencies in the range of 6240 to 6740 MHz. And the NRAO, for its part, uses a subset of that range to identify methanol in space "that is abundant in star-forming regions and serves as a galactic beacon of star-forming activity."

I don’t know about other searches, but the frequencies examined here are in a pretty narrow band around 1420 MHz.

Not only that - that frequency range is reserved for fixed satellite communications as the primary user (in the US)....
