K3 Calibration Problem

[Dave, G4AON]

*Joseph

1. In order to use the ATU and the PA, you need to firstly enable them
in the menu, then turn the power switch off and on again. The rig reads
in the accessories and will recognise them (I fell for that one with the
PA).

2. I also tried too hard to set the power levels... Basically once you
have calibrated the Wattmeter (and then only if you have an accurate
external Wattmeter), you then ignore the menu and external power meters.
Just follow the instructions in the manual, it's easy to fall into the
trap of trying to set levels manually, this is not how you calibrate the
power settings the K3 will automatically set the power for you when you
select 5 Watts (or 50W on high power) and press the "TUNE" button, this
needs to be done on all bands... If you have really fouled up, reset the
K3 to the initial start-up conditions by pressing and holding the
SHIFT/LO knob while powering up. Don't forget to calibrate the VCO
before going on to the power setting.

I am trying to perform the Ref Oscillator Calibration for my 1 ppm
device:


Method 3 (1 ppm TCXO Option):

* Locate the CONFIG:REF CAL menu entry.  Tap 1 to change the name to REF
xxC.

* Locate the calibration data sheet, which shows frequency vs.
temperature over a wide range.

* For each data point, tap 2 or 3 to select the calibration temperature,
then use VFO A to set the specified oscillator frequency in Hz.

 
and am getting nowhere fast.  In step 1, I see the 'REF CAL' menu
displayed by VFO B, but tapping '1' doesn't change the name off the
menu; it merely performs the usual 'tap' function of that switch:  A/B.


Thanks for any help from anyone!

The firmware has not been written yet for the 1PPM TCXO3-1 table
calibration, so use one of the other two methods for now.  It will still be
more stable than the standard TCXO3.  QRX for a future firmware release to
do the table entry.
