  A spectroscopic support survey of 103 objects observed by the MOST satellite
is presented; 96 are variable stars with 83 of them being new MOST
variable-star detections or stars with variability types verified and/or
modified on the basis of the MOST data. Analysis of 241 medium-resolution
spectra using the broadening-functions formalism yielded radial velocities,
projected rotational velocities (for 31 targets for which it was possible) and
spectral type estimates. Seven new spectroscopic binaries were discovered;
orbital solutions are given for two of them (HD73709, and GSC 0814-0323). The
visual binary HD46180 was found to be composed of two close binary stars
(eclipsing and non-eclipsing one) very probably forming a physical quadruple
system.
