The title says it all. I am using a Flex 6300 with the latest software version and the latest version from WSJT. I also installed Meinberg's time interface as per Ria, N2RJ's instructions. I believe I have the setup done correctly as I can see WSJT receiving as well as I am able to transmit. The WSJT program's receive meter shows about half scale (40db), so I don't think I'm over driving anything. The receive window in WSJT just stays blank. Any help would be greatly appreciated. I have been trying for 3 days and can't figure it out.
