Today, we released version 1.1 of SDRuno. New features include a calibrated power measurement facility, an SNR meter and automatic S-meter calibration. There are many additional improvements and fixes. To find out more about all the additional features, documentation can be found on http://www.sdrplay.com/docs/SDRplay_SDRuno_Release_Notes.pdf and the software is available to download from http://www.sdrplay.com/windows.html – For non RSP users (e.g. RTL-SDR and other EXTIO-based SDRs), the bandwidth limit has been increased to 2.5MHz.

Paul Jones and Mike Ladd have worked tirelessly to get the new features documented in an updated version of the SDRuno Cookbook: http://www.nn4f.com/SDRuno-cookbook.pdf

There’s always a lot of debate about Dynamic Range and the performance of the various SDRs out there – Mike Kokotov, Z33T has written an excellent article explaining Dynamic Range and how decimation can improve dynamic range. The article can be found on http://www.qsl.net/z33t/dynamic_range_eng.html
