Radial velocity data are presented for 10 W UMa-type systems–GZ And, V417 Aql, LS Del, EF Dra, V829 Her, FG Hya, AP Leo, UV Lyn, BB Peg, and AQ Psc–together with preliminary circular-orbit determinations of spectroscopic elements, with the main goal of obtaining mean radial velocities and mass ratios for these systems. This is the first part of a series that will contain radial velocity data for northern hemisphere, short-period eclipsing binaries, accessible to medium-resolution spectroscopic studies with 1.8 m-class telescopes.
