If the answer is the latter, it would be difficult if you've inserted 7600. Thanks to all in advance for offering your many insights.
fly safe,
As a very new pilot I had a radio failure in the Birmingham zone. Setting 7700 to declare a Mayday before setting 7600 for radio failure and then landing didn’t save me from receiving a very threatening letter from the CAA for not knowing the radio failure procedure for Birmingham.
From the difficulty they had trying to get the signal lamp out of the door I concluded that it had been a very long time since someone had landed at Birmingham with radio failure.
