Not on 205 but I get a carrier on 203.5. It is a power company SCADA channel. I get lots of carriers on my long wave panorama. Most are the power line SCADA channels. They usually don't cause interference but I do have one at 251 Khz and it could cause interference with Alger Chaine but it is not strong enough most of the time. I believe I have two or three of these systems in my area. Not sure yet. At least two. They sometimes turn them off and when turned on they will all vary in frequency for a while. When the power comp. shuts them down I get what I call the Binaca Blast. A large number of carriers about 1k apart and they will subside after 20 to 30 minutes. In that case it is major interference for a while. I believe each SCADA channel is PSK 30 or 31. About 30 Hz wide.
