    Returned to old signle-pol receiver (RCP duplicates the LCP signal)

    Strong parallel-hand fringes, no or weak cross-hand fringes. SNR of RR fringe is somewhat larger than the one for LL fringe.

    The amplitude vs channels plots of both LL and RR exhibit a strange "bowl" shape, with amplitudes in edge channels up to 4 times higher than the amplitude in the central ones.

    After the return back to the old signle-pol receiver the problem persists.
