IC-7100 FT8 transmit timing problem.
When transmitting the timing (DT) is off by up to 3 sec. (varies). Receiving is no problem.
Not an RFI issue. Both stations running low power into dummy load.
Both computers are on exact time. Change of PC does not help. Same problem with both WSJt-X and JTDX.
IC-7100 TX delay is set to off.
