AB  - [100]-tilt YBa 2 Cu 3 O 7-x bicrystal Josephson junctions with the resistances R n from 0.4 up to 400 Ohm have been fabricated and studied with Josephson admittance spectroscopy. In these junctions intrinsic ac shunting has been found, that is characterized by broadband admittance Y 1 of the order of R n -1 and low-level resonant contributions with the admittances ReY 2 (f k ) of two signs. Two different types of resonances have been observed and ascribed to the excitation of transverse and longitudinal IR-active phonons in YBa 2 Cu 3 O 7-x material by Josephson oscillations.
