I tried to run Telemachus on linux (Kubuntu 13.04, KSP version 0.21.1.0). The antennae do exist and they do show the menu when right-clicked, but Open Link doesn't do anything! KSP Debug Console never shows anything related to Telemachus. I put the mod to the GameData folder. I also tried putting the contents of Telemachus Parts and Plugins folders to the KSP Parts and Plugins folders, but it didn't make a difference. I'm going to have a LAN-party with my friends on the 10th of August and Telemachus would be really nice. I can make do with MechJeb if I must. Anyways, thank you Rich for creating such an awesome mod!
