“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“
