This is only the case with dBm where 0 dBm is indeed 1 mW across 600

dB with nothing behind expresses any kind of logarithmic ratio.

Thanks, all. I suspect that Walt may have the answer, that 0dB is the point at
which further power brings an increase in noise or distortion.

dB is a logarithmic scale of ratios. 10 deciBell is one Bell, or a factor of

I'm pretty sure they don't rate receivers and amplifiers at absolute
maximum output. Beyond "0 db" there's considerable degradation in the
signal-to-noise ratio, so they rate them at some point below that.
