SDRuno 1.2 Release Notes (27th October 2017)

Summary: This release addresses a number of usability issues and bug fixes as well as implementing some new features.

The main change to the SP1 display has been to separate the resolution bandwidth (RBW) control from the zoom function. This gives the user the ability to trade off CPU load vs quality of the spectrum display. A number of defaults have also been changed to improve the quality of the main spectrum display.

Some other key changes are that the frequency entry can now be made in MHz as well as the default kHz entry.

Control + W now allows you to save the workspace to a specified slot.

Keypad buttons now not only take you to the specified band, but the sample rate and decimation are changed to enable “band framing” – allowing you to see all of the band within the display.

Another new feature is the ability to store input RF power level and signal to noise ratio (SNR) for a given signal as defined by the displayed VFO in a CSV file. This file is updated at a rate you select in the SP1 settings panel so you can see how the power level and SNR change over time. Note that this is accurate to around 1dB and is a calibrated measurement to the input of the RSP.
