[Elecraft] Re: K2 Remote/Server

[Leigh L. Klotz, Jr.]

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.
