SDR called the RSPdx.
The RSPdx is a replacement for the highly successful RSP2 and RSP2pro SDR receivers, which have been extensively redesigned to provide enhanced performance with additional and improved pre-selection filters, improved intermodulation performance, the addition of a user selectable DAB notch filter and more software selectable attenuation steps. The RSPdx, when used in conjunction with SDRplay’s own SDRuno software, introduces a special HDR (High Dynamic Range) mode for reception within selected bands below 2MHz. HDR mode delivers improved intermodulation performance and fewer spurious responses for those challenging bands. This will be of particular interest to MW/ LW DXers and NDB hunters.
Having multiple antenna ports means that you can keep several antennas connected at once for comparison purposes. It also allows you to quickly move from one end of the radio spectrum to the other with say, a discone for VHF and above on one port, and a magnetic loop for lower frequencies on another. The introduction of a BNC connector for one of the antennas on the RSPdx is a result of the growing popularity of magnetic loops which typically come with a BNC termination.
Like all the RSPs from SDRplay, the RSPdx is optimised to work with SDRuno SDR software for Windows. SDRuno has evolved a lot over the years since it was adapted by SDRplay from the original “Studio1” SDR programme. Earlier this year, a powerful integrated scanner was added – this works with all the RSPs, including the original RSP1. Also added was a diversity tuning feature, for use with the dual-tuner RSPduo, for additional signal enhancement and noise cancellation.
