Radio Station Happiness

I understand that the Radio Station generates a level of Happiness for all the Vault Dwellers and high Charisma is helpful as well, but my question is when the Radio Station is successful in recruiting a new Dweller and the room is waiting for your to tap it, does the Radio Station continue to provide Happiness?
I don't always want to bring a new Survivor into the Vault but I do want the Happiness Boost from a fully upgraded and fully staffed (Charisma 10) Radio Station.

if you've seen ,what has happened with a new update,it was written there that radio is "passively" increasing happiness of all dwellers in the vault,but if you tap on the radio once,there is a chance to decide whether you want it to broadcast outside(+inside) or just inside therefore attract new dwellers(and increase happiness) or just increase happiness. According to my experience, if you have 3 merged rooms and all 6 people there with high charisma it is "happier" than 3 merged and ,say, 4 people there with same stats
