If you're reading off SNR numbers off your set's diagnostic page, be aware that they should do perfectly well until you hit the 15-17 dB range. With the digital system, as long as the minimum ratio is maintained, reception won't be any difference between a "good enough" number and a very high value (30-35 dB SNR). The problem is that, if it drops just too low, it falls off the "digital cliff".
The SNR reading isn't really a signal power meter for measuring the signal levels.
