The authors report measurements of the noise in a 2-hole r.f. SQUID fabricated from bulk YBCO by an erosion technique in the frequency range 30mHz to 1kHz. Above 100Hz the noise is essentially white with an rms value of 5.10/sup -4/..cap alpha..o/..sqrt..Hz and is dominated by noise from the electronics. Below 10Hz the noise power rises as l/f/sup 0.9/.
