Today I was QRV on 20m. And happened no decode problem. It as follows picture.
Therefore my decode sequence is not synchronize calling signal. So finish the time sequence but no decode.
Yesterday also, a few stations as same as problem had. The PC clock is most important matter of JT65 mode.
If JT65 mode operat start then before checking PC clock as normal.
However, some person don't understand the importance of PC clock.
If no adjust PC clock that never contact for nobody.
