Abstract: The PT-symmetric photoconductivity has been detected for the first time in microwave-irradiated heterostructures based on thick Hg$_{1-x}$Cd$_x$Te films with the CdTe content x corresponding to the topological phase although the magnetic field symmetry ($T$ symmetry) and the symmetry in the positions of potential contact pairs ($P$ symmetry) are not conserved separately. The microwave photoconductivity in similar heterostructures based on the trivial Hg$_{1-x}$Cd$_x$Te phase is both $P$- and $T$-symmetric.
