For PSK and other similar text-based digital modes, I have developed a
protocol and a client and a server. My Java client is available open
source at http://wa5znu.org/rpsk and I have given the server back to the
gMFSK project. I also wrote a client for my GPRS handheld phone, and
have not completed it, but screenshots are available.
So far, I have focused only on the novel elements, the TX and RX, and
not rig control.
The protocol transfers only the character, phase, and spectrum data, and
has vastly reduced network bandwidth requirements over sending an audio
stream.
As a future project, I hope to regularize the underlying protocol using
XML and apply some recent research results in optimal XML compression
when the standards bodies issue their recommendations. This approach
will open the door to a truly cross-platform, cross-rig, extensible
protocol for remote operation.
If someone wants to try out RPSK, please let me know and I will leave
the RX part on for your scheduled receive time.

Leigh.

VNC is certainly an option, and I've used it to run MixW remotely, but
as Larry suggests it's quite sluggish, even with a decent connection. I
use it to administer my web server and it sometimes goes very slow even
though I've got ADSL at this end and the server is connected to a fat
pipe at a data center.
And you still need something to carry the audio. There's a program on
my site called AudioLink that will do this, but it's basically the
prototype for the audio streaming for K2Net and hasn't been updated to
the current level of K2Net, which is more resilient now and has lower
latency than earlier versions.
I'd recommend anyone wanting audio linking software to work with VNC to
download the demo package for the audio streaming components at
www.lakeofsoft.com and use one of the demo applications.
