Jason, I just successfully hooked up a a remote 915mhz RF circuit to accomplish GTI disconnect in a AC coupled system when the backup generator starts. I think this is the discussion you are referring to. I’m on the road right now but will post details including the source of the send/receive units when I get back to a computer. It’s been working for over two weeks now with no problems whatsoever.
