I'm trying to send probes to Eve, and am having trouble being able to communicate with my landing probe once I separate from the stage that got me to Eve orbit.
The stage that remains in Eve orbit has 2 RA-2 Relay Antennas, and my Kerbin DSN Ground station has bee upgraded to L3.
I obviously want to have control over my probes during re-entry, so a big dish is out of the question, but when using a Communotron 16, or even the probe core (a Probodobodyne OKTO), as soon as I separate from the stage that has my relay antennas, I loose all control over the probe. I was expecting that the probe core, either via its internal antenna, or the Communotron 16, would relay via my stage and its RA-2's back to Kerbin, but no. The only antenna that give me any kind of connection is a DTS-M1, and that shows as communicating directly back to Kerbin, rather than through the relay. A DTS-M1 is not going to survive Eve re-entry.
I don't think its a range issue, as I loose control of my landing probe as soon as I separate, I have extended antennas, and even tried re-orienting the stage with relays just in case the stage body was occluding the signal from my probe to the relay antenna, but no luck.
The KSpedia show a table that gives ranges for different combinations of antennas - Class 0 (Probes) unto class 5, as well as the different upgrade levels of the Kerbin Ground Station, but I can't see in the parts guide what class a particular antenna would be.
I am using KSP 1.21.1604 on Mac.
Any thoughts/suggestions?
Thanks
Paul
