Software Defined Radio. The way I am using with weewx is with a USB tuner built for DVB-T TV broadcasts in other countries (but not the U.S.) that use the RTL2832U chipset. People discovered that these tuners could cover a much larger range than DVB-T and have been using them for receiving all kinds of stuff, including the 433 MHz signals used by wireless weather sensors (and a lot of other stuff in the home).
rtl_sdr handles controlling the radio, and rtl_433 decodes packets from known devices. The weewx sdr driver uses rtl_433 to get the packets of information directly from the weather sensor. The radio receivers are available for $10-$20 all over the place online. Since they were intended for TV in other countries the antenna connection is often unusual, but that doesn't matter if you are using the antenna that comes with it. My antenna is a monopole, so it needs to be sitting on a piece of metal to work best. It's magnetic, so I've just got it stuck to the side panel of an old computer.
