While talking to a local friend on channel 29 in antioch illinois, we heard ssb on 29 and checked usb. There were a group of French speaking only dx chatter. We only heard the French voices and no other language and sounded like they were also trying to talk dx. One person replied back by saying "no english, Francis ". Only for about 10 minuets and they were gone. Happened late night Friday early Saturday on June 13.
