I have tried several times to work OM3LO on 20 meters RTTY. I get no response other than one time he said he could not copy the station calling. I have not noted a problem working any other station even in contests. Has anyone else had a problem with him using WL. Maybe it's on his end, maybe on mine or it may be his TU can not handle WL's stop bit as noted by someone else about a week ago. Don AF4Z
