Oliver Jowett 19082d92ea Measure signal power / noise power (at least in 2.4MHz mode). 
Switch signalLevel back to a power measurement, don't put SNR in there.
But make it a 0.0 - 1.0 double so we're not scaling everywhere.

Adjust for the amplitude offset when calculating power.

Adapt everything else to the new scheme.
