[Elecraft] k3 problem

[Don Wilhelm]

Bob,

The list of error codes start on page 68 of the
K3 manual.
ERR EFX does not exist, but ERR TXF is valid - it says the filter 
configured for transmit is not valid.
That is relatively easy to see with K3 Utility - Configuration tab, 
Configure Xtal Filters.
The filter for CW, DATA, SSB must be the 2.7 or 2.8 kHz filter.
For ESSB it needs to be the 6Khz filter and AM can use either the 6kHz 
or 13kHz filter
And for FM it must be the 13kHz filter.

Is there any chance he has turned on ESSB mode in the menu and does not 
have the 6kHz filter installed?

73,
Don W3FPR
