Setting this bit causes IQ packets to become corrupted in rx.

In protocol 1 this is Common Mercury Frequency and is used for diversity rx to lock RX1 and RX2 frequency. I propose the HL2 does not need to use this bit. See https://groups.google.com/d/msg/hermes-lite/FYS15G-tWhs/SnOt-8KDAwAJ

Behavior of this bit should either be documented or left such that setting this bit has no undesired effect?

Code in git main now ignores this bit. Will be in next gateware release.
