The FreeDV project, http://freedv.org/tiki-index.php is in the process
of integrating Hamlib to handle PTT initially. At the moment, FreeDV
has its own PTT implementation that does not handle CAT PTT. Of course,
they have some questions which I've been able to answer but I'm certain
more will be asked that will draw on the experience of those of you who
develop applications using Hamlib. Also, it's likely that more
questions regarding Hamlib internals will arise so anyone more familiar
with that area (Stephane?) can also contribute. Stuart Longland,
VK4MSL, is working on Hamlib integration.
As I see it, FreeDV is one of the most important bits of amateur radio
software to come along in a while. FreeDV builds upon the LGPL'ed
Codec2, http://www.rowetel.com/blog/?page_id=452 which is providing SSB
quality speech in about 1.6 kHz bandwidth. Codec2 is free of patents,
NDAs, and the like and promises to provide a viable alternative to the
AMBE codec used by Icom's D-Star, et. al. Codec2 is developed by David
I encourage partcipation in the digitalvoice Google Group (viewing is
limited to members), http://groups.google.com/group/digitalvoice to help
the developers continue their work.
