Talks from the 2020 HamSCI Convention (Held Online)

HamSCI is an organization dedicated citizen radio science and specifically the "publicity and promotion of projects that advance scientific research and understanding through amateur radio activities". Recently they held their HamSCI 2020 workshop online, and the videos are now available on the Ham Radio 2.0 YouTube channel. Several of the projects mentioned in the talks involve the use of software defined radios.

Come join HamSCI at its third annual workshop! Due to restrictions caused by the COVID-19 Coronavirus, this year's workshop will he held as a virtual, eletronic workshop. The meeting will take place March 20-21, 2020 using Zoom Webinar Services hosted by The University of Scranton in Scranton, PA . The primary objective of the HamSCI workshop is to bring together the amateur radio community and professional scientists. The theme of the 2020 HamSCI Workshop is "The Auroral Connection: How does the aurora affect amateur radio, and what can we learn about the aurora from radio techniques?" Invited speakers include Dr. Elizabeth MacDonald, NASA Scientist and founder of Aurorasaurus, Dr. James LaBelle, Dartmouth Space Scientist and expert on radio aurora, and Dave Hallidy K2DH, an expert in ham radio auroral communication.

One talk discusses the HamSCI personal weather station project, which is an SDR and Raspberry Pi based solution that monitors HF signals like WSPR, as well as characterizing HF noise, detecting lightning and ionospheric disturbances.

Another talk discusses the TangerineSDR, which is an open source SDR currently in development by TAPR. The goal of the TangerineSDR is to be a sub $500 SDR with a focus on space science, academic research as well as general amateur use.

New Accessibility Plugin for SDR#

In the past we've seen several SDR# plugins released by Eddie MacDonald, and now thanks to recent updates to the core of SDR#, he's been able to work on and release a new accessibility plugin for SDR#. Eddie writes -

I have created a new plugin which provides keyboard shortcuts, an on screen display and a new improved toolbar for the new native toolbar area that Prog has provided to plugin developers.

There are many new and improved toolbar buttons available.

Many, many keyboard shortcuts including the ability to directly enter the frequency easily from the keyboard.

I am currently working on incorporating a screen reader into the plugin to aid the blind in using SDR#.

The plugin is available from his website at

SDR# Tuner Knob, Night Mode and FFT Grabber Plugins have a new home

Recently we've posted about Eddie MacDonald's several releases of new plugins for the popular SDR# software. Recently he's released a tuner knob plugin which provides a visual frequency tuning knob that is useful for those running on touchscreen hardware, a 'dark mode' plugin which reduces the brightness of SDR# and compresses the UI a little, and an FFT grabber plugin which allows for easy screenshots of the FFT and waterfall spectrum's to be taken.

Eddie notes that all his plugins now have an actual home website at This is where he will release updates and new plugins from now on.

If you are interested in discovering more SDR# plugins, we have a large list available here.

SDR# Plugin: FFT Window Screen Grabber

Recently Eddie MacDonald has been pumping out simple but useful plugins for SDR# including the SDR# Dark Mode and Visual Tuner Knob plugins. Recently he released a new plugin called "FFT Window Screen Grabber". This plugin simply helps you to easily take a screenshot of the FFT and waterfall displays in SDR#. It could be a useful plugin if you are constantly finding interesting signals that you want to document, or upload to

The plugin can be downloaded from his thread in our forums. Note: Updated plugins now available at

SDR# Dark Mode Plugin

A few days ago Eddie MacDonald released his Tuner Knob plugin for SDR#. Today he's released a new plugin called "SDR# Dark Mode" over on our forums. This plugin is very simple in that is just makes the SDR# interface black, which should be better on the eyes those using the app at night. The plugin also adds two other options which allow you move the tuning toolbar to the bottom of the screen and remove all padding to save some screen space. The three options in the plugin are:

"Night Mode" or "Regular Mode" - allowing the app to be black or not
"Bottom Tool Bar" - allows you to place the radio control tool bar on the top or bottom of the app
"Remove Padding" - remove the 10px border around all the controls giving you a tiny amount of more workable space.

The plugin can be downloaded from the file uploaded on the third post on the announcement thread. Note: Updated plugins now available at

Dark Mode + Remove Padding

Visual Tuner Knob Plugin for SDR#

Thank you to Eddie MacDonald for submitting his new SDR# plugin to us via our forums. Eddie's plugin is called the 'Tuner Knob Plugin', and simply enables a visual tuner knob on the screen for adjusting the frequency. This plugin could be useful especially for those running SDR# on touchscreen tablets or laptops. To install the plugin copy the .dll file to the SDR# directory and copy and paste the magicline.txt into the plugins.xml file. We tested the plugin on our PC and found it to run well.

We have uploaded the plugin here for all to download. Note: Updated plugins now available at

Eddie writes about the plugin:

Programming the plugins is not so easy considering their is very little documentation and few examples on the net. There may be a few bugs I have not caught (but i hope i have caught them all.)

This DLL was compiled and tested on a Windows 7 x64 machine and the DLL is compiled for both x86 and x64 platforms. I have tested it on SDR# Version v1.0.0.1635

I am not certain which previous versions it may or may not run on. However, being built on the 4.6 .Net framework it should work with Win7 on.

I built this plugin because i got tired of holding down buttons and waiting for the frequency changes. I figured this was a simpler method (even though some people hate rotary style controls on windows) It works exceptionally well with a touch screen.

As previously mentioned in the forum post I created the 'remote' to test my programming for future plugins for DSP

While some may not find a use for the remote I made it this way for my wife who like to cruise the dial and just see what she can pick up.
