SDRplay Launches the RSP1B

SDRplay, a manufacturer of popular low cost software defined radio devices have just launched their "RSP1B" model. This is a refresh of their popular lowest price model, the RSP1A. The changes include a new steel enclosure, significantly improved noise performance under 1 MHz and in the  50 - 60 MHz region, noticeable noise improvements in the 3.5 - 5.5 MHz and 250 - 320 MHz range, and improved signal handling at HF frequencies.

The RSP1A remains for sale at US$117 + shipping, and the new RSP1B sells for US$132.25 + shipping.

SDRplay introduces the RSP1B SDR receiver

Their press release reads:

SDRplay Limited is announcing the launch of a new Software Defined Radio receiver product – the RSP1B. The RSP1B is an enhanced version of the popular RSP1A powerful wideband full featured 14-bit SDR which covers the RF spectrum from 1kHz to 2GHz. The RSP1B comes in a rugged black painted steel case and has significantly improved noise performance. All it needs is a computer and an antenna to provide excellent communications receiver functionality. It comes with a choice of SDRunoTM for Windows and multiplatform SDRconnect (TM) SDR software for Windows, MacOS and Linux (supplied free of charge by SDRplay). It allows users to monitor up to 10MHz of spectrum at a time. A documented API allows developers to create new demodulators or applications around the platform.

The RSP1B has the following additional benefits compared to our lowest cost device, the RSP1A:

  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.

As is the case for the other RSP family members, SDRplay will work with the developers of the popular third party SDR receiver software packages to maximise compatibility. SDRplay will also provide multiplatform driver and API support which includes Windows, Linux, Mac, Android and Raspberry Pi.

The RSP1B is available to purchase direct from SDRplay or from SDRplay’s authorised resellers where it is expected to retail at approximately £106 GBP or $133 USD (excluding taxes or shipping). A list of SDRplay’s authorised resellers can be found at
