Precise optical positions in the FKS system of a sample of 17 compact extragalactic radio sources in the northern hemisphere have been determined from plates taken with the 1.5-m L. Figl telescope of the Vienna Observatory to evaluate the astrometric accuracy of that telescope and provide pilot data for an extended astrometric program. Tabulated results include IAU and other designation, right ascension and declination with mean errors, and epoch. An average accuracy based on several plates for the source positions of 0.04 arcsecond has been obtained. There is a need for astrometry of many more faint objects.
