I was going to write a report about the first Melbourne radio ratings period following the 3AW/Magic frequency swap [1], and then I realised that the ratings periods in Melbourne overlap.
Ratings #3 (which I covered here [2]) went from February 12 to April 29, which places it before the frequency swap.
Ratings #4, which I was about to write a report for, went from March 26 to June 10, which puts the frequency swap in the middle of the ratings period.
Ratings #5 started on May 7 (six days after the frequency swap) and finished on July 29, I will write a report about this ratings period when the results are published, as this will provide a direct comparison of the time directly before, and directly after, the frequency swap.
