The SDRplay RSP software defined radio<\/p><\/div>\n

Many thanks to Jon Hudson with SDRplay<\/a>, who shares\u00a0the following announcement:<\/p>\n

We are pleased to announce release 1.8.0 of the API for the RSP. This is a major upgrade to the API with new features and an improved gain map which should result in improved performance over a key portion of the gain control range. Currently this API is available for Windows only, but versions for Linux and Mac OS and Android will follow shortly.<\/p>\n

The API now incorporates automatic post tuner DC offset correction and I\/Q compensation. This will almost completely eliminate the DC centre spike that was previously present in zero IF mode and also correct for amplitude and phase errors in the I\/Q signal paths that can lead to in-band images when strong signals are present.<\/p>\n

There is a new gain map for the RSP which should help improve the receiver noise floor for gain reduction settings in the range of 59-78 dB. To achieve this, the IF gain control range has been increased from 59 to 78 dB. In addition, the user can now turn the LNA on or off at any point within the IF gain control range. This means that the LNA can remain on for gain reduction settings of up to 78 dB, whereas previously the maximum gain reduction that could be attained whilst the LNA was on was only 59 dB. Being able to leave the LNA on will result in improvements in the receiver noise performance for gain reductions in the range of 59 to 78 dB. The upper 19 dB of the IF gain control range have now been disabled. In practice this part of the gain control range was useless as trying to operate within this region always lead to receiver overload even when signals were very weak.<\/p>\n

To fully exploit the features of this new API release, we have also issued release 3.5 of the ExtIO plugin. This plugin will work with HDSDR, SDR sharp (releases 1361 or earlier) and Studio 1. Automatic I\/Q compensation and DC offset correction will work with later versions of SDR sharp, but we will need to update the native plugin for users of these later versions to be access the new gain map.<\/p>\n

Similarly, users of SDR Console will gain the benefit of automatic DC offset compensation and I\/Q correction, but will not yet be able to access the new gain map. We hope that a version of SDR console that unlocks this feature will become available in the near future.<\/p>\n

Until a new release of SDR-Console is available, you can copy the API into the SDR-Console installation directory…<\/p>\n

from C:\\Program Files\\MiricsSDR\\API\\x64\\mir_sdr_api.dll to C:\\Program Files\\SDR-RADIO-PRO.com\\mir_sdr_api.dll<\/em><\/p>\n

The API installer has also contains an extra certificate to be more user friendly for Windows XP, Vista and Windows 7 users.<\/p>\n

The new API and ExtIO plugin can be downloaded from our website at: www.sdrplay.com\/windows.html<\/a><\/strong><\/p><\/blockquote>\n

Many thanks for sharing this, John! \u00a0I’ll update my RSP today.<\/p>\n
