You can generate the ticks by hand.  Try

	mytik = Range[-80, -3];
	mytik = {#, ToString[FortranForm[Exp[#]]], {.003, 0}} & /@ mytik;

	MultipleListPlot[Transpose[{dx, Log[dy]}], SymbolShape ->
{PlotSymbol[Box, 		2]}, Axes -> False, Frame -> True,
	    FrameTicks -> {Automatic, mytik, None, None}

Not sure that this is what you intended though.  You may want to try
different scalling to reduce the range.  Alternatively, you can plot every
n-th label in your tick function, but this is what your original is doing
