Our radio footprint might be rapidly decreasing, but our IR signature, roughly proportional to our total energy use, has always been much greater than our radio signiture, and has been rapidly increasing. Admittedly, IR signiture isn't nearly as conspicuous against ambient natural background of our planet and sun as radio frequency, but with sufficient resolving power, an advanced technic civilization ought to be able to pin point us simply by our inevitable thermal dynamic leakage as we use more and more energy.
