I'm having some trouble with the "integrated 3.0 Km omnidirectional always on" antennas that are supposed to be built into the probe cores. This antenna doesn't seem to function properly in my game. For example of how they are supposed to work- in this video https://youtu.be/0sUjsI9SpB4?t=297 He builds a simple probe rocket with no added antenna, launches it, and then loses signal after a short distance. It's a demonstration for why you need an additional antenna to get further than 3km. However, If I try to launch this exact same rocket in my own game(just probe core+SRB), my probe has no connection at the launchpad and I can not stage or do anything. My issue is, I'm building a space station, and I wanted to use little probe RCS tugs to re-arrange and dock all the different modules. They should always be within 3 km of the space station, which will always have a connection to KSC, so I shouldn't need anything other than the integrated probe core antenna. However, they are not working as they should- just like how the probe SRB doesn't work for me. Do I really have to add DP-10 antennas to my orbital construction RCS tugs? Edit: Nevermind, looks like you need the "Remote Tech" node unlocked for the integrated antenna to work. Didn't realize.
