[Elecraft] K3 Delta-f Indicator not working

[Dan Sherwood]

All,

I have a relatively new K3, firmware version 4.39.  When setting split
around 10.110 MHz CW, I noticed the amber delta-f indicator not lighting
when entering split mode.  The unit clearly showed split mode on LCD display
with the TX pointing to the secondary frequency, with TX frequency a few kHz
up the band.  I had been trying to dig an extremely weak signal out of the
noise, and had disabled the subreceiver briefly to try to pick up a little
extra gain.  I don¹t remember if the light had actually ever lit.

As a test, I enabled RIT and XIT.  The indicators around that encoder
worked, but still not delta-f below the power button.  I was able to restore
functionality to the delta-f indicator when power cycling the K3.  Having
been a former Kenwood user, I¹m used to having the display frequency change
on transmit in split mode, so not sure really split is working or not when
this indicator does not work.  Sometimes I forget to disable split when done
with it and embarrass myself, so I need all the help I can get!

Any ideas?  (No running PC attached to K3 at the time, so HRD or other
logging S/W not an issue this time around.  I do have P3 with latest F/W
attached.)

Thanks and 73,
