Its been like 5 hours, i have a lvl 2 radio room with a guy that has full charisma and another with 7/10.

0 dwellers have come to my vault since i built it.

I'm not in a need of dwellers because i have a pretty big baby cycle going, but its annoying cause my best guy is in there and literally no one is showing up.

plus, the dwellers usually have better stats than the babies.

That's odd. I've had two show up since opening up my radio room this afternoon. One every 2 hours or so. I have two in there. It's one room only. The two dwellers in there are by no means oratorical geniuses.

Do you see a countdown when selecting the radio room? You should have a countdown showing you how much time is left until a new dweller shows up. If you have the countdown and are still not getting any dwellers then it's odd.

The way I understand it, when the timer ends each time, there is a 'chance' to call in a new wanderer from the wasteland.

Rk is right every 2 or so hours there is a chance that a new dweller can arrive.. upgrading the radio room increases the chance that a dweller will arrive.

Have you tried upgrading your radio room?

My bad. I've had dwellers arrive each time the timer ran out, so I just assumed that's how it was rather than it being by chance.

In any case, as others have said, upgrading the radio room again may help + merging it to expand it. Rooms have to be the same level to merge, though.

I have a level 2 radio room that has been merged once. But prior to that, it was level 1 and just a single room. I don't know, you should be getting dwellers at least some of the time.

Many hours more for me, just had my first visitor. radio room not upgraded though.

I thought mine wasn't working either at first, I didn't know it was by "chance" at the end of each timer.
