We show that hyperoctahedral Whittaker functions---diagonalizing an openquantum Toda chain with one-sided boundary potentials of Morse type---satisfy adual system of difference equations in the spectral variable. This extends awell-known bispectral duality between the nonperturbed open quantum Toda chainand a strong-coupling limit of the rational Macdonald-Ruijsenaars differenceoperators. It is manifest from the difference equations in question that thehyperoctahedral Whittaker function is entire as a function of the spectralvariable.
