Appologies if this is a bit of a daft question with an obvious answer, but why do Coventry ATC change frequencies? For example, in the week (day), Tower is 124.8 & Radar/app 119.25 then at night/weekends, Tower/app is combined in 119.25 and Radar becomes 122.0. Why don't they stick to the same freq's all the time?
