The world is full of software-defined radio (SDR), but HackRF One has a rather unique position – thanks to its vast maximum bandwidth of 20 MHz. With an up-converter, this combination covers more than 70 percent of the whole HF range from 3 to 30 MHz. Even better: with proper software you can record and play this enormous band!

However, this stunning bandwidth is achieved by a moderate resolution of 8 bit, resulting in a dynamic range of just nearly 50 dB. Or the half of SDRs like Elad’s FDM-S2.

Anyway. I wanted to know in practice what you can actually do with such a set at a budget price plus mostly free software. The results surprised even me: Properly used, this combination convinced as a quite decent performer on HF! The world map above shows some of the stations received with the set (see insert bottom left) to test its performance.

SdrDx, SwDb and VFO Suite for the PC require an Intel CPU, running Windows XP or (possibly) a later version of the OS. SdrDx requires an RFSPACE AFEDRI, Andrus , FUNcube Dongle SDR, or a Soundcard-based SDR, or pre-recorded RF files (see above for some of these) in order to do anything useful; in the specific cases of the SDR-IQ and SDR-14, you’ll also need a server application that puts the SDR-IQ on the network. SdrDx handles the RFSPACE SDRs and compatibles (and near-compatibles) via the network , it does not directly interface with them via USB. You must run these applications out of the folders they are supplied in, as they depend on files in those folders.
