On real devices, signal strength is always a negative number when represented in dBm. A more interesting range is to use dBmV (which is what Kaffeine does, for example). The conversion from the two units are simple: dBmV = dBm - 108 Usually, signal strength ranges up to 100dBmV. Adjust the maximum value to be around 74 dBmV, when there's no frequency shift, which represents a good signal. With that, Kaffeine displays it a lot better.
