Kevin, Awesome mod!! While working on my PID control algorithm I really wanted some telemetry. So I added a LOG function which appends a message to a file on the archive volume (if it is within range). This will be very useful for debugging and making graphs. If you are not in range of KSP, then the messages are lost to the depths of space. Glad to have a use for those antenna. I sent a pull request on github for you. Let me know if you'd like me to change it to better fit your vision or throw it away if you don't like it. Just thought others might enjoy. Example delete speedlog from volume archive. until altitude > 50000 { LOG speedlog "Alt:" + altitude + " Spd:" + surfacespeed. wait 1. }. Cheers
