[Elecraft] KX2 & FT8

[Andy Durbin]

You said you receive FT8 signals fine.  If that means you are decoding then time sync is not likely to be the cause of you problem.  If decoding ok your time error can be easily assessed by looking at the average time error of the signals you decode.  Almost any computer is capable of maintaining adequate time accuracy for short term FT8 operation if it is set within a second at the start of the operating session.   Many manage mobile operation with no time sync capability.  Some use a GPS receiver as a time source.

The most common problem for FT8 TX seems to be that the keying method is not compatible with the modulation signal source.   If data vox keying is available it is an easy way to bypass that problem.  No KX2 here so can't tell you how to configure for that rig but it should be easy to see if the KX2 is being modulated (no modulation = no power output).
