Jon Petter Skagmo has a nice blog detailing how he used rapsberry pi to remote control Yeasu FT-857 and uses talkkonnect as the push to talk IP radio link solution. Check his blog by Clicking here.
It always gives me inspiration the different ways talkkonnect is used. If you use talkkonnect be sure to let me know how you are using it and also send me some pictures so I can post them here for other interested people to see.
