In plain language: Synchronize the computer clock for FT8 with a reliable network time service or disciplined local time source so transmit and receive periods align closely with other stations.
Why the station behaves this way
FT8 decoders tolerate only limited timing error. A clock can show the correct minute yet be offset enough in seconds to lose decodes, especially after sleep or without internet access.
A common wrong turn
Manually setting the clock by eye or assuming the operating system always resynchronizes in the field is unreliable.
What to do at the radio
Enable a trusted time client, verify the actual offset before operating, resync after sleep or network changes, carry a GPS or other offline source when needed, and never change time during a transmission.
Operating boundary
Use current equipment instructions, legal operating limits, the exact signal path, and observed conditions. A connector, software label, transformer ratio, or forecast value does not prove complete-system performance.
