Yeah, that's BS for sure. Sounds like someone has a big amp and is trying to be a bully. I love those types as most of the time in person they are some piss ant that is scared to death to have any face to face contact!! I use power from time to time and don't bleed over any channels. Clean in equals clean out. A splatter box indeed it is!! He is bleeding over more than just 11 meters I promise that!! If wanted he could easily Be found, maybe that's why he shut up lol. Anyway have a blessed day an enjoy the dx'ing while you can!!
