EchoLink
From Wildsong
EchoLink is a closed source Windows program that allows communication over 2 meter radio by connecting radios and the Internet.
Why is there no source code for the clunky old Windows program?

SvxLink is a project that develops software targeting the ham radio community. It started out as an EchoLink application for Linux back in 2003 but has now evolved to be something much more advanced.
There is an EchoLib library
Mac
There is source code for the Mac version "EchoMac" https://sourceforge.net/projects/echomac/
It's old too.
Hardware
I think a couple of my rigs contain the hardware.
