    3same receiver 18/21 cm

    4there is no special X-band receiver, S/X only

    5depending on band number required and other requirements (Pcal), band change may take from 10 min to 8 hours:

    1) 10 min - automatic change between secondary focus receivers;

    2) 30 min - same as above plus required antenna to be pointed to Zenith and manual operations in the receiver cabin (e.g. Pcal change);

    3) 8 hours - only few recerivers (cryogenic units) could be cooled simultaneously, time needed to cool down additinal receiver.
