I have the Universal Remote Control RFX-250 Remote Antenna.The RF light is staying on constantly, and I can't figure out where this antenna is receiving RF from. I have removed the batteries from every Universal remote mx-350 I have, and the RF receive light still stays on. Some commands I send via RF from my MX-350 remotes to my three ir receivers in the basement do get through, but obviously the rogue RF the antenna is receiving is causing a big problem. There are emitters in the system that are staying on constantly due to this rogue RF. I have powered down every piece of equipment in the system including the Universal Remote Control RFX-250 Remote Antenna, but when I power the system back up I still keep receiving the rogue RF. This problem did not exist 24 hours ago. Any ideas on what is causing this rogue RF? Thanks for the help.
