SDR# Version 1920 Released

A few days ago SDRSharp version 1920 was released. SDRSharp (SDR#) is a popular Windows program that is affiliated with Airspy SDR dongles, but is compatible with RTL-SDR and various other SDRs as well. The latest version gets rid of the relatively resource heavy Telerik UI library and replaces it with a much lighter weight library.

The author of SDR#, @lambdaprog, notes that v.1920 reduces memory usage by 85% and CPU utilization by 50%. The new version also improves scalability for high sample rates and number of spectrum slices and improves plugin compatibility. Several AOR brand SDRs are also now supported in v.1920.

On the note regarding improved plugin compatibility, we've noticed that in the v.1920 update the IF Average plugin has begun working again. The IF Average plugin is used for Hydrogen line radio astronomy experiments. In the past we had to use older versions of SDR# to make it work. We have updated our Hydrogen line tutorial to reflect this.

Been using SDR# for many years and am very satisfied with it along with the AirSpy HF Plus Discovery. Works great for ham, shortwave, CB and HF utility monitoring. Very thankful to those who were responsible for developing the software and hardware.

The author of SDR# is a total nutcase though.

i honestly regret ever buying any airspy hardware. its not like it performs amazing against the competition either…

Disagree. The Airspy products are some of the best budget SDRs in terms of quality and design. It rivals some of the higher-end scientific SDRs, especially when it comes to deep-space satellite RX.

Why would he be a nutcase? His software is pretty good and is the industry standard more or less. The Airspy products are proper SDR recievers and not just another repurposed TV tuner that has an exploited I/Q sample mode like the SDRPlay and RTL-SDR products. Not to mention the paywall behind the SDRPlay software.

I will have to tr (narrow band of qualityy it as well as read more about it. I may have a friend install it in a spare old machine I have. That has a version of SDR# 14.3 something I think. I have tried some other software and had problems with the display showing a narrrow image of the magnitude of the signals).
