It is my opinion that the K3s rates the use of a proper quality
frequency counter.
I bought a used, "lab grade" counter with an OXCO, and supply it with an
external GPSDO signal.
Is it required? No, not really
I initially calibrated the K3s with one of the government time
beacons... not
You can also use CHU for frequency standard calibration check depending on
propagation.

John,
You do not need a frequency counter to calibrate the K3S, use Method 2
with WWV, it is just as accurate.
Actually it is likely more accurate than you would get with a <$100
frequency counter, unless you calibrate the frequency counter
beforehand. I suspect any frequency counter costing
I think you would do much better getting something like a used Racal-Dana 1992
or the like of of ebay with the crystal oven.

Frequency counters will also need to be calibrated. I have been
quite happy using WWV with my K3, and you can't beat the price.

What? I didn’t know that Elecraft offered frequency counters. Or, do you mean
something like the XG2, a signal source for testing rigs?

I am considering buying a frequency counter to calibrate my K3S. I see that
Amazon has several for <$100. Has anyone had any experience with these?
Are they just a waste of money?
Thanks,

Don,
Thanks for the info regarding the XG2/Freq Ctr. Could you recommend a
make/model freq ctr for kit building? Iv'e looked on the MFJ web site, but if
you have better ideas it would be of great help. Preferably one that is not too
expensive!!

Dennis,
I would not recommend ANY kit frequency counter if one will be using it
for calibration purposes - unless you have some means of calibrating it.
I can recommend a recently calibrated HP or Fluke frequency counter -
you can sometimes find them used at auction sites, but they may not
I have a little portable counter (ancient - late 70's technology) that uses
a 4 MHz crystal. It was nothing fancy. It didn't even have a way to adjust
the crystal frequency. I had to add a small piston trimmer cap to the
design. I used it commercially to confirm that shipboard transmitters were
I can recommend the M3 FPM1 Frequency Counter and Power Meter..

It's a great kit but the calibration problem still remains. For
calibration, M3 sells the RF Calibrator which is NOT a kit, but does
come calibrated by M3.

Thanks for your assistance, I found the problem and the Freq. counter is

I've been busy building my K2. I have completed the control and front panel
boards with all checks reading as they should. Have just completed Part I of
the RF board and everything checks out fine except when I test the frequency
counter probe on the left side of C22 the display
Terry,
Is there a possibility that you have the pins in the housing reversed? The
shield should be closest to the side panel.
There is just not much to the frequency probe - a piece of coax with a 10 pf
capacitor in series with the center conductor, so not really much to go
wrong.
To test the
I am doing the 4 MHz oscillator check and I can't seem to get a reading on the
probe. Should I make note of this now or wait until I get into the 4 MHz
counter calibration later in the build? Is there any other alternative to
checking the calibration without using the probe that was supplied
Can someone recommend a general purpose frequency counter
suitable for setting C22 in a K2 and for other ham shack uses?

Glenn,
The qualities of a frequency counter capable of setting the K2 reference
accurately is that it be capable of counting down to 1 Hz and have adequate
accuracy - which means that it must be properly calibrated. The calibration
is more important than having any particular counter. Most any
