F/A-18C TACAN channel & Datalink Functionality

NFM-000, 24.4
In MIDS-equipped aircraft, TACAN functionality is embedded in the MIDS terminal (...). Because the upper antenna filter is fixed, it filters A/A TACAN frequencies on channels 1-36 and 64-99 (X and Y). A/A TACAN channels should be chosen outside of these ranges. The upper filter makes the top antenna unusable for T/R (Air to Ground) TACAN channels 1-29 X and Y, 47X to 63X and 64Y to 92Y. For TACAN channels in these ranges, the bottom antenna is the only antenna for TACAN. [This] causes reduced ranges for DME at channels within the range of the filter when flying directly away from the TACAN station.
in other words, white squares good, other colored squares bad. TACAN channel 1 is also good per Wags:
Per the previous post, we have changed the Link-16 frequency to 1092.5 MHz. As such, TCN channels 68 and 69 both X and Y should be avoided.

This will be for the next update and will allow the default TCN channel 1 to not interfere with Link-16.
