Abstract:
    We present HI observations of the galaxies in the first list of the
    Karachentsev catalog of previously unknown nearby dwarf galaxies
    (Karachentseva & Karachentsev, 1998, Cat. J/A+AS/127/409). This
    survey covers all known nearby galaxy groups within the Local Volume
    (i.e. within 10Mpc) and their environment, that is about 25% of the
    total sky. A total of 257 galaxies have been observed with a detection
    rate of 60%. We searched a frequency band corresponding to
    heliocentric radial velocities from -470km/s to ~+4000km/s.
    Non-detections are either due to limited coverage in radial velocity,
    confusion with Local HI (mainly in the velocity range -140km/s to
    +20km/s), or lack of sensitivity for very weak emission. 25% of the
    detected galaxies are located within the Local Volume. Those galaxies
    are dwarf galaxies judged by their optical linear diameter
    (1.4±0.2kpc on the average), their mean total HI mass
    (4.6x107M☉), and their observed linewidths (39km/s).
