K3 APF Problem???

[radioshoppe]

Hi Folks,

After watching the progress of APF for a few months I decided it was time to upgrade to the latest firmware (4.25) and give it a try.  When pressing the DUAL PB there is a LOUD clip and the CW is gone.  Turning the SHIFT control products one LOUD clip for each 50 Hz step.  I went to CONFIG and could not find DUEL PB to ascertain APF was selected.  Now this gets complicated so follow closely.  There is no DUEL PB in the VFO B space between DIGOUT1 and EXT ALC as the latest manual (D9 - Pg 55) indicates there should be.  However, when EXT ALC is selected APF is show in VFO A.  It appears that in my K3 all values in the second column of the manual (displayed in VFO A) beginning with EXT ALC is shifted up one entry from the first column of the manual (displayed in VFO B).  BTW, turning VFO A knob does change the VFO A display from APF to DUEL PB and back again when in EXT ALC.

I have taken a picture and will be happy to display it someplace if anyone is interested in seeing it. 

I've read the verbiage on page 35 about APF and there is nothing there that seems to help.  Anyone have any ideas or can tell me what I'm doing wrong.

Take pride in the USA. 73

Make sure that the front panel code is also updated. The proper version for 4.25 is 1.14.
Also make sure the proper DSP table is present when you update; it should be DTBL0014.HEX.
If all the versions aren't synchronized you can have problems like you describe.
