I never understood the DBm scale, which my RX340 has in addition to the
usual S unit scale.
Can one of you radio eggheads explain exactly what "DBm" measures? I
think it means decibels per meter, but that still tells me nothing. Is
it "meter" as in wavelength?

Hopefully it's in minus units as it refers to decibels above a
milliWatt.

Thanks. Milliwatts makes sense. I must have been thinking of millivolts
per meter, which I think is how broadcast station signal coverage areas
are measured. Or maybe it's microvolts per meter.
