[Elecraft] K3 Test Mode Problem

[Don Wilhelm]

Harvey,

You may have inadvertently changed the transmit filter for CW or SSB 
around the time you updated the firmware.  Use either K3 Utility or the 
configuration menu to set the SSB transmit filter to your 2.7 or 2.8 kHz 
filter. 
ERR TXF is telling you that the wrong transmit filter bandwidth has been 
set.  See page 65 of the manual.

73,
