So wait.... Now the least powerful Antenna, the Communotron mini thing, has super-powerful relay capability that takes precedence over anything else? And the high-gains can now no longer transmit science, only telemetry? Is that right? I have a crummy little lander on the Mun with a deployable low-gain and deployable high-gain. When I click relay to 'yes' on the low-gain (which should not be able to reach Kerbin), all of my satellites around Kerbin suddenly connect to the KSC through the Mun lander's mini antenna. When I stow it away and use only the high-gain, I can control the Mun lander but the data rate says 'none' and I can't transmit any science.
