Should the power levels fluctuate up and down a couple of db when looking at a channel? 

How bad should the AC hum be on a system? When in demod mode listing to the spectrum I can hear a AC hum in there that is changing frequencies and audio level.
It sounds like a bad AC power supply to me but that may be normal on a system that is using AC powred amps. I'm more at home in a DC environment. I am going to measure the output with the meter and see what the hum level is. What percentage hum is acceptable?
