The RSP1B is an enhanced version of the RSP1A our popular lowest cost receiver—it is a powerful wideband full featured 14 bit SDR and perfect as an all round general coverage communications receiver plus much much more.  

The key advantages over the RSP1A are that it comes in strong black painted steel case instead of plastic, and (compared to the RSP1A) has significantly improved noise performance below 1MHz (i.e for 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. It also has it has improved signal handling at HF frequencies compared to the RSP1A.

RSP1B Pricing – £106 GBP or $133USD excluding tax and shipping  – INCLUDES unlimited copies of SDRuno (Windows) and SDRconnect (Windows, MacOS, Linux/Raspberry Pi) software. Windows users, please note that right now, due to recent Microsoft kernel driver signing rule changes, the RSP1B will only work with Windows 10 and later. We are investigating this issue.

The RSP1B covers the complete radio spectrum from 1kHz (VLF) to 2GHz (Microwaves) with up to a massive 10MHz visible bandwidth and the companion SDRuno software has all the popular ham bands and shortwave broadcast bands as “presets” for instant set-up.
