Third, slip the transformer's wedge wires beneath the wooden pins, one wire per bolt.In fact, an ATU will pre-select the range of frequencies you want to hear and by default reject the rest. This can improve signal-to-noise ratio, so improving your perception of the signal you want to hear. A modern radio passes a band of frequencies (band pass tuning or filtering) for processing. In that band, signals large and small appear.
