K3 Test Mode Problem

The test mode doesn't operate like it did with previous firmware revs. I'm using an MH-2 mic with K3 s/n 2231 with firmware 2.78. When I key up, vfo B shows 'ERR TXF' and I can hear myself in the speaker. When I unkey I can't key the mic again without pressing any key pad on the front panel to reset the error on vfo B first. Am I doing something wrong? I used to be able to key the mic repeatedly in the test mode without any error hangups.

Re: K3 Test Mode Problem

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.
