In the present paper we consider the Type-2.x and Type-3.x extraterrestrial von- Neumann probes and study the problem of their detectability by the world's largest single-dish radio telescope: the Five-hundred-meter Aperture Spherical Radio Telescope (FAST). For this purpose we estimate the radio spectral parameters and analyse the obtained results in the context of technical characteristics of FAST. As a result, it is shown that FAST can detect both the galactic and extragalactic self-replicating probes with high precision.
