Asymmetrical frequency usage

[Capkirk123]

For some reason, the frequency used for an uplink and downlink is not the same. The uplink consumes the expected amount of bandwidth (1 bit/Hz for BPSK with no encoder), but the downlink only consumes 38% of the expected bandwidth.

The RA planner and debugger both correctly report that the uplink and downlink speed are the same or close to the same.

I would expect the uplink and downlink to consume the same bandwidth for stations of the same modulation and encoding properties. My best guess as to what is happening is that Skopos is incorrectly using the encoding/modulation settings of the transmitter rather than of the worst member of the pair, and therefore applying higher-order modulation schemes for the satellite antenna to the downlink.

Decreasing the antenna tech level through save-file editing, the spectrum usage increases back to the expected value. I strongly suspect Skopos is choosing the transmitting antenna rather than the worst antenna when calculating spectrum usage.

This doesn't appear to be happening with new satellites, my screwing around with encoders may have fixed it. I'm leaving it open until I can test further
