Abstract
A query on the behaviour of a 2.84 GHz ms-resolution receiver developed by Jinet al. at the Beijing Astronomical Observatory (BAO) in the early 1980s is raised in this paper. As an inappropriate use of an electrically controlled attenuator (ECA) and a A/D converter in the receiver, taking an attenuation by 12 db (i.e., a factor of 16) in the intermediate frequency (IF) flux for the equivalent of a data shift to the right by 4 bits, along with other design defects, could have made artificial errors creep into the observations, we throw doubt upon the 205 published solar ultrafast fine structure (UFFS) data taken with such a receiver.
