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, 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 which will contain radial velocity data for Northern-hemisphere, short-period eclipsing binaries, accessible to medium-resolution spectroscopic studies with 1.8-meter class telescopes.
