Scientific paper

The 85-90-GHz receiving system with a maser was successfully tested as a front end at the 22-m radio telescope of the Crimean Astrophysical Observatory. The detector noise temperature is 60 +/-10 K and the maser bandwidth is about 40 MHz. HCN, H(C-13)N, and H(C-13)O(+) lines with a 100-kHz resolution were observed in some molecular clouds. Examples of the measured spectra are presented.
