Results are presented from a multifrequency radio continuum survey of Markarian galaxies (MRKs) and are supplemented by IRAS infrared data from the Faint Source Survey. Radio data are presented for 899 MRKs observed at {nu}=4.755GHz with the NRAO-Green Bank 300 foot (91m) telescope, including nearly 88% of those objects in Markarian list VI-XIV. In addition, 1.415GHz measurements of 258 MRKs, over 30% of the MRKs accessible from NAIC-Arecibo, are reported. Radio continuum observations of smaller numbers of MRKs were made at 10.63GHz and at 23.1GHz and are also presented.
