For anyone getting into the world of Software Defined Radio, the first purchase should be an RTL-SDR TV tuner. With a cheap, $20 USB TV tuner, you can listen to just about anything between 50 and 1750 MHz. You can’t send, the sample rate isn’t that great, but this USB dongle gives you everything you need to begin your explorations of the radio spectrum.
Your second Software Defined Radio purchase is a matter of contention. There are a lot of options out there for expanding a rig, and the HackRF is a serious contender to expand an SDR rig. You get 10 MHz to 6 Gigahertz operating frequency, 20 million samples per second, and the ability to transmit. You have your license, right?
Unfortunately the HackRF is a little expensive and is unavailable everywhere. [Gareth] is leading the charge and producing the HackRF Blue, a cost-reduced version of the HackRF designed by [Michael Ossmann].
The HackRF Blue’s feature set is virtually identical, and the RF performance is basically the same: both the Blue and the HackRF One can get data from 125kHz RFID cards. All software and firmware is interchangeable. If you were waiting on another run of the HackRF, here ‘ya go.
[Gareth] and the HackRF Blue team are doing something rather interesting with their crowdfunding campaign: they’re giving away Blues to underprivileged hackerspaces, with hackerspaces from Togo, Bosnia, Iran, India, and Detroit slated to get a HackRF Blue if the campaign succeeds.
Thanks [Praetorian] and [Brendan] for sending this in.
