The oxygen content dependence of 63Cu NQR at the Cu(l) site and proton NMR have been measured in the antiferromagnetic phase of powdered samples of hydrogen-doped YBa2Cu306+xHv (0.07 ≤ X ≤ 0.17 and V = 1) from 4.2 to 90 K. The spectrum of 1H NMR is a single line and the line width increases below 15 Kdue to magnetic interactions. The enhancements of [formula-ommited] and [formula-ommited] of 63Cu(l)NQR occur around 35 and 15 K, respectively. These enhancements increase with increasing oxygen concentration. The maximum values of [formula-ommited] and [formula-ommited] for the sample with X = 0.17 reach 200 sec-1 and more than 7 msec-1, respectively. The predominant source for the relaxation mechanism of 63Cu(l) NQR and the line broadening of 1H NMR are found to be the fluctuating magnetic field due to the staggered Cu2+ moments.
