	Suppose we want to listen to 900 MHz, like all the other cool hipster hacker kids who are doing HamProxy SDR projects. ~~Okay~~, we~~'re gonna listen to~~ 920 MHz. We're reading ~~at about~~ 2 ~~billion~~ samples ~~per~~ second ~~(take a minute~~ to ~~contemplate that: that~~'s ~~absolutely astounding~~). We can specify a number of samples, ~~this obviously~~ doesn't correspond to the number of samples ~~it's~~ taking per second because the two don't match up at all:		Suppose we want to listen to 900 MHz, like all the other cool hipster hacker kids who are doing HamProxy SDR projects. Since radio operators are the hipsters of the airwaves, always wanting to find a new, hip frequency to use that no one else is using, we will do that, and use 920 MHz.

			We'll be reading somewhere around 2-3 million samples pre second. Give that time to sink in - it's mind-boggling. In the time it takes you to drink a cup of coffee, it probably generates more information than all the bureaucrats of royal France did over the course of a century. (It could have been bureaucrats from anywhere, really, but I picked French because the word bureaucrat is from French.)

			We can specify a number of samples, which doesn't correspond to the number of samples the RTL-SDR device is taking per second because the two don't match up at all:

			We've got our basic "Hello SDR World" program up and running. We can grab raw data. We can feed the raw data to an audio player. So far, so AWESOME.

			But here's what comes next:
			* Gnu Radio
			* Ham It Up for better antennas
			* Adapters
