Abstract :
An 
-band ruby maser radiometer is discussed. In particular, recent developments in the equipment design are detailed. Observations of radio sources are discussed, and response curves with and without the maser preamplifier are given. The detection of 3.45 cm radiation from the planet Saturn is reported, and the equivalent blackbody disk temperature calculated. The future of the maser amplifier in radio astronomy is considered.
