MCMC comparison of projected PBH correlation functions with z≈6 quasar angular auto-correlation data yields posterior constraints f_PBH∼10^{-3}, m_PBH∼10^{12}M_⊙ for Poisson models and ξ_eff≃2.1, r_cl≃76 Mpc for clustered models.
LOFAR2.0, FAST Core Array and BINGO are forecast to bound f_PBH < 0.16 (M>1 Msun), <0.39 (M>10 Msun) and <0.39 (M>0.1 Msun) respectively from null FRB lensing.
