Shift Control Problem

[Earl N5ZM]

I just received my K3 S/N 3223 (FW 3.30/DSP 2.26) back from Aptos and
I now seem to have a problem with the Shift FC not correct for
DATA/FSK-D mode. Crystal Filters:2.7-5Pole, 1.8-8 Pole and 250-8 pole.

The center star is at *1.36 and it needs to be at *2.21.
When I narrow the BW the signal disappears, but I can get it back by
manually moving the Shift Control to 2.20.

I have compared all my CONFIG and MAIN settings with a local with a K3
and they pretty well match up.

Any ideas??

Earl N5ZM..

Found it!! The Mark/Space on the Pitch setting was wrong. Was set to
1275/170 instead of 2125/170.

Still new to the radio and had forgot about that setting..

All is OK now..

Earl,

There is a Mark/Shift and Pitch Selection - See the manual page 31.
Set to your data mode (I assume AFSK or FSK-D), then hold the PITCH
button - rotate the VFO A knob to tell the K3 what mark frequency and
shift that you are using.  If you are using a computer application, the
mark frequency and the shift must match in both the K3 and the application.
