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?

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
now working.
I used one of the 2n's from the RF board and replaced Q9. But, this
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
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
