Experimental data on signal and noise characteristics of high--Tc RF SQUIDs with large inductance of quantization loop are presented. The SQUIDs were produced by a thick--film HTS--technique of painting on the Y2BaCuO5 substrate. For the first time, a steady quantum interference was observed in RF SQUID with the inductance as large as LS=6.6 nH, that is, 60 times higher than the fluctuation inductance LF≃10-10H at the liquid nitrogen temperature T=77 K. A new method is offered to evaluate the sensitivity of RF SQUID with optimum inductance of the quantization loop.
