I recently bought a used 6500. I am seeing 0.3 seconds delay on every FT8 signal. My test setup: Kenwood TS590, Win 7 PC, V1.9 of WSJT-X, Flex6500. I set the time on the PC and recorded a number of stations using the TS590. Most stations were right around zero DT. I then connected the Flex to the same PC (& same antenna) and most signals had DT of 0.3. I also compared my TS990 on a second PC running WSJT-X. In every case, the DT (delta in time) with the Flex6500 was 0.3 seconds later, regardless of the actual DT number. I expected some delay with a Flex, but 300ms seems high. I did a master reset but it did not change anything. I notice the same delay when changing something simple - like AF volume on my Maestro. I want to know if the 300ms delay is typical in Flex or is there something wrong with my radio.
