I saw a post you made there. I guess since it's a general SWL group, they all have their own interests and don't dig what you do. I, for one, like it all, so keep it up.
It's no different in the ham groups on FB. Mention a mode that someone doesn't like, a brand of radio, hell, personal favorite frequency or band you like to operate on, and someone will come talking trash. I just scroll on past.
