We present the result of 27 ASCA observations of 26 radio-quiet quasars (RQQs) from the PG survey. All the RQQs were detected except 2 BALQSOs. We find the variability characteristics of the sources to be consistent with Seyf-1s. A powerlaw offers an acceptable description of the time-averaged spectra in the 2-10 keV (RQQ-frame) band for all but 1 dataset. The photon indices vary from object to object over the range 1.5~
