Billy Boy, 60 HZ is AC (60 cycles per second), 300 MHZ is AC (300 million cycles per second). No no Billy Boy, infomation cannot be modulated on carriers that are DC (0HZ). It would be a mess, 135 channels in the same space would not work.It's not possible anyway since DC (0 HZ) will not propogate the airways, or glass, so what the hell eh? Yes you can read a DC (0 HZ) voltage for the light level. This is a referance voltage your reading calibrated so you can determine what the light level is into the node. Ex: ( your reading 1.5 volts) 1.5 log X10 = 1.76DBM. A basic understanding of electricity may help you during these evil times. BS can only take you far.
