We describe the results of observations with the 100m Robert C. Byrd Green Bank Telescope (GBT) in the HI line of 54 nearby dwarf galaxies found mainly in the DESI Legacy Imaging Surveys. Of these, we detected 35 galaxies with the following median parameters: the HI-flux of 0.53 Jy km/s, heliocentric velocity of 1123 km/s, and $W_{50}$ line width of 33 km/s. Most of them are isolated irregular objects, and some have turned out to be new probable satellites of nearby disc galaxies: NGC 2787, NGC 3556, NGC 4490, and NGC 5055. The detected galaxies are predominantly gas-rich systems with a median gaseous-mass-to-stellar-mass ratio of 2.41.
