KRX3

[VE3WDM]

Good morning all,
I have successfully installed the KRX3 in my K3 I now beginning the calibration procedures.  First it is the synthesizer, I entered CONFIG:VCO MD the only two parameters I can find are Nor 41 and RF 127. Any more rotation of the vfo knob changes the RF setting. I believe I am not able to find the CAL parameter as I have not set TECH MD to ON. But in rotating the VFO and changing some settings in either NOR or RF are these saved or does the rig have to be in TECH MD ON first? If they are saved does this mean I have to redo the synthesizer cal procedure for the K3 again?

  Mike,

Yes, you will have to set TECH MD to ON as indicated in the manual.  Set
the VCO MD to CAL and SUB and exit the menu, the operation is
automatic.  The values you see are the result of the calibration.
You may turn TECH MD off after you finish the calibrations.

Don'
 Have I changed any of the synthesizer settings when I rotated the VFO knob earlier and changed the RF settings. I was not sure if I also changed the NOR setting in this menu either? But I hope with the MD setting to off nothing was changed.

  Mike,

Read the manual menu chart of menu explanations and you will discover
better than I can tell you.
If you set it back to NOR 127, then exit the menu and change bands, it
will be restored to the prior settings.

Since the calibration is more or less automatic, I see no problem in
re-doing the calibration, so (in TECH MODE) set it to CAL and exit the
menu - it will be done.

I wonder if Mike was having trouble finding the "rf cal" position.  That
should be found by turning the VFO A knob CLOCKWISE from the NOR setting
that you find it on when you select VCO MD in the config menu.    73, Guy.

Don and Guy, Thanks very much for the help I re-did the synthesizer cal for the main receiver and then did the sub receiver. I then went into the K3 utility and did the RF gain calibration for both main and sub receivers.Oh and also entered the filter data for the sub as well. All is going FB and I am just in the process of discovering the sub receiver.  
Thanks again for your time and help.
