[Linux-aus] FLOSS-and-Linux-friendly weather stations?

[Kim Oldfield]

Hi Mikey,

rtl-433 looks nice, but it isn't clear what hardware it works with.

Are you suggesting that most rtl-sdr devices will work? Is searching 
ebay or aliexpress for "usb rtl-sdr" a good way to find a reasonably 
priced device to use with rtl-433?

Regards,
Kim
