Sorry - Why?
7700 is emergency, 7600 is a radio failure. The two are totally separate.
Therefore - radio failure only, 7600 only.
For a flight conducted VFR wholly in class 'G' the question you really want to ask yourself is - "when do you squawk 7600?". Might be worth having a read of
this thread to read various viewpoints.
