Simon Brown (G4ELI) author of SDR-RADIO has recently started writing another program called Greyline for Windows, and is still moving it forward. We are now up to Version1 Build 222.
I wrote about this in early October http://g1kqh.blogspot.co.uk/2014/10/new-software.html
Since then the Great Circle map has been given a zoom option, and some minor bugs have been ironed out. I also notice there is now an interface for the Yaesu FT-3000 that has been added, not much reference to this at the moment, and as I do not own this radio I cannot test it out? However, I feel there are great things to come from this program, so it is well worth a download and keeping an eye on its website for future updates:
