Back in December of last year we posted about the Indiegogo campaign for the HackRF Blue, a lower cost clone of the HackRF One software defined radio. They were able to achieve a lower cost by better component sourcing and manufacturing choices, thus reducing the cost from $299 to $200. The HackRF Blue Indiegogo campaign was successful and most of the HackRF Blue’s have now been shipped and delivered to backers. If you need help getting started with the HackRF Blue see http://hackrfblue.com/getting-started/. To get started on Windows, simply use Zadig like with the RTL-SDR, and use SDR# which has built in HackRF support.
The specs of the official HackRF One (and by extension the HackRF Blue) have also recently been changed. They now officially acknowledge that the HackRF One is capable of operating at a frequency down to about 1 MHz. They write:
Now that we’ve seen consistent low frequency performance across multiple manufacturing runs, we’re comfortable changing the official specification: HackRF One operates from 1 MHz to 6 GHz. Try attaching a long wire antenna to listen to shortwave radio!
Recently some people have been considering which mid priced SDR to upgrade to from their RTL-SDR. Our opinion is this: The HackRF has pretty poor RX performance, probably the same as, or even worse than the RTL-SDR, so we suggest you buy it only if you want TX capabilities or need operation above 1.7 – 2 GHz. If you only need RX then we suggest you choose the Airspy or SDRPlay as they have much better RX performance. See our list of SDRs for more possible options.
