Warnings:

This is not the Sputnik-1 signal. There are a number of authentic recordings of the signal that can be found on Sputnik 1 in the external links. Please don't link this into the article on Sputnik-1. It is not Sputnik-2 or 3 either, so nobody really knows what it is. It does appear to be some kind of PDM signal, maybe from a Soviet spacecraft.
