Currently Operating:
Current radiometers on the west 26-m telescope include the frequencies 1.4 GHz for HI measurements, and 6 and 12 GHz for methanol detection. Installation of a 340-MHz receiver is in place. The east 26-m telescope has a 1.4 GHz radiometer. The 12.2-m telescope has prime focus feeds supporting 6 cm (3.3-4.4 GHz) and 3 cm (10.9-12.75 GHz), and a removable cassegrain subreflector and feed assembly is available for 6-5 cm (6.6-7.7 GHz) operation. The precision surface of the 12.2-m antenna will support operation at 1, 0.8, 0.7, and 0.6 cm (21.7-24.1, 36.0-36.5, 41.0-45.0, and 48.0-49.0 GHz). The 4.6-m antenna is configured for 21 cm (1.42 GHz) reception, and feeds for 5, 4.5, and 2 cm (6.0, 6.6, and 12.0-15.6 GHz) are planned for this antenna.
