Re: [Elecraft] Frequency display on P3?

+1, yup!  Mine is spot on, as calibrated... as in less than 1 Hz error rate.

If I feed an accurate signal from a waveform generator into my K3S, on
the P3 it appears right about 120 Hz higher than the actual frequency.
This seems to be independent of the mode the K3S is in. What causes that?

I noticed this when I had my K3S/P3 running while working the ARRL
Frequency Measurement Test with other gear, and was curious about it.

Thanks much,

Re: [Elecraft] Frequency display on P3?

[Alan Bloom]

The P3 has a menu entry to calibrate its frequency  MENU:Ref Cal 

The calibration prodedure is on page 37 of the manual.  I like to use an
AM broadcast station (preferably near the top of the band) for
calibration because these frequencies are highly accurate and AM mode
puts the carrier right at the center of the P3 display.

It sounds like you need to do the frequency calibration as documented on
page 39 of the manual

[Elecraft] Frequency display on P3?

[Frank O'Donnell]

Here's what I'm sure is a beginner question.

If I feed an accurate signal from a waveform generator into my K3S, on 
the P3 it appears right about 120 Hz higher than the actual frequency. 
This seems to be independent of the mode the K3S is in. What causes that?


I noticed this when I had my K3S/P3 running while working the ARRL 
Frequency Measurement Test with other gear, and was curious about it.


Thanks much,

Frank K6FOD
