1dB is a human-detectable change.
2dB could make the difference between a QSO and no QSO with marginal S/N ratio. 1 "standard" S-unit of 6dB can probably make the difference between marginal S/N and armchair copy. If copy is already armchair, Reg's totally right. No change. I like to make a lot of QSO's that are down in the noise, though. 73, Dan |
