Yeah, it's hard to know if people use the word "repeater" colloquially or technically, so I always repeat the Meshtastic warning about that role since it has a high likelihood of being detrimental to the mesh in the area.
Hope you find something suitable because it's a fun project. I only get a few hits each month (less in the winter it seems) but it's cool when you randomly pick up someone from miles away and have a chat.
