We will present recent results of observations of various astronomical objects with the radio telescopes UTR-2 below 32 MHz, and prospects for GURT below 70 MHz.

UTR-2 (Ukrainian T-shape Radiotelescope, v2) is operational since about 40 years but the recent implementation of digital receivers enhanced its capabilities. We will present results on sporadic solar radio emission (Type III, Type II, Type IV bursts, S-bursts, drift pairs, spikes), recombination radio lines, Jupiter radio emission (with 15 nanosecond time resolution), Saturn's lightning, the sounding of pulsar magnetosphere, a transient survey of the Northern sky, a survey of decametric sources and background, interplanetary and ionospheric scintillations, and flare stars.

Recently, the first sections of GURT (the Giant Ukrainian Radio Telescope) became operational. We will present first test observations and prospects.
