SDRPlay range expanded with two new SDR receivers

Finally, the long-awaited new SDRPlay receivers, the RSP1B and RSPdx-R2, have arrived. Let's see how these new devices differ from their predecessors and why the changes were necessary.

Due to problems with the global supply chain, the existing SDR products had to be slightly redesigned by the manufacturer to ensure a continuous supply to their partners.

Improvements have been incorporated into each new member of the RSP family, and the changes have given the manufacturer the opportunity to offer performance improvements in the new products while ensuring supply.


SDRPlay announced the release of the RSP1B in January 2024, which is an enhanced version of the RSP1A. With this, the manufacturer has also ended the production of RSP1A receivers.

The main additional advantages of the RSP1B over the RSP1A are:

  1. It is housed in a strong black painted steel case.
  2. It has significantly improved noise performance below 1MHz (i.e for MF, LF and below), and in the 50-60 MHz region. There are also noticeable noise improvements in the 3.5-5.5MHz and 250-320MHz spectrum.
  3. It has improved signal handling at HF frequencies.

SDRPlay RSPdx-R2

On May 10, 2024, SDRPlay introduced the new RSPdx-R2 receiver, an enhanced version of the RSPdx.

The RSPdx-R2 provides up to 10 MHz of spectrum visibility from 1kHZ to 2GHz, with no gaps. Compared to the RSPdx, improvements have been made for MF frequencies and below, improved noise performance below 1MHz, improved dynamic range below 2MHz in both tuner mode and HDR mode.

In other respects, it has almost the same additional features as the cheaper single-antenna SDR RSP1B, but with a few differences.

The RSPdx-R2 has 3 software selectable inputs, including a BNC input up to 200MHz, 500 kHz LPF for LF/VLF, HDR mode for enhanced performance below 2MHz (using free SDRuno or SDRconnect software), Notch filters on all inputs.
