We report on an attempt of detecting radio emissions (similar to Jupiter S-bursts) from 20 candidate exoplanets located within ~25 parsecs distance from the Earth. The combination of the world largest decameter radio telescope UTR-2, located near Kharkov, Ukraine, broad-band multichannel acousto-optical spectrometer with digitized output, and special post-processing software for eliminating man-made interference resulted in high sensitivity (down to ~50 mJy at ~5 min. integration time, ~8 MHz bandwidth) observational data of the total duration about 100 hours obtained within a period of 1999-2002. After preprocessing mainly consisting in interference rejection from the data, the search for frequency-drifting spectral patterns have been performed with a method similar to de-dispersion technique used in pulsar signal analysis. Several positive detections have been proven to be spurious, originated from non-ideal interference removal. A marginal detection (still remains to be confirmed with additional observations) is found in the source Lalande 211185 (HD 117176).
