K144RFLK Offsets?

[KC5VF]

I just installed the K144RFLK in my K3.  I have the .5 ppm oven controlled crystal in my radio.

When I calculate the new offsets, I ended up with a 0.104 Hz offset for the 144-146 range and a 1.4 Hz offset for the 146-148 range.
Following the instructions and converting these amounts to KHz, I ended up with no offsets to enter into the radio, as the resulting amounts were smaller than the allowable significant digits for the XVn OFFSET settings.

I set the OFS to 0 for both of them.  Is this correct?

It would seem to me that if you have the more accurate reference oscillator crystal in the radio, that you could just change the manual to enter a zero for both offsets.

Hi Mark,

If your value of REFCAL is very close to 49,380,000 then the XVn offsets
will be very small, and may even be zero.

BTW, what is the value of REFCAL on your radio?

73,

Paul

My REF frequency is 49.380.000

Right on the money,  Since my radio reads out directly on the REF frequency, that is why I was suggesting putting a statement in the manual to just go ahead and set the Offsets to 0 for that case.

Mark,

I agree with you.  If your REFCAL is on the button, or fairly close (which I'll have to calculate) , the XVn values should then be set to zero.   I'll talk to our technical writer and address the changes to the manual.

Thanks,

paul
