Re: [Elecraft] Frequency Counter for Calibrating K3S

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

Re: [Elecraft] Frequency Counter for Calibrating K3S

You can also use CHU for frequency standard calibration check depending on propagation. 3330.000, 7850.000, and 14670.000kHz   73, Mike AC5P On Saturday, February 11, 2017 12:20 PM, John Stengrevics wrote: Thanks all for the comments. I think I will stick

Re: [Elecraft] Frequency Counter for Calibrating K3S

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. From: stengrevics To: elecraft@mailman.qth.net Sent: Saturday, February 11, 2017 12:39 PM Subject: [Elecraft] Frequency Counter

Re: [Elecraft] Frequency Counter for Calibrating K3S

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. 73 Bill AE6JV On 2/11/17 at 9:39 AM, jstengrev...@comcast.net (stengrevics) wrote: I am considering buying a frequency counter to calibrate my K3S. I see that

What? I didn’t know that Elecraft offered frequency counters. Or, do you mean something like the XG2, a signal source for testing rigs? 73, phil, K7PEH > On Feb 11, 2017, at 9:39 AM, stengrevics wrote: > > I am considering buying a frequency counter to calibrate

Re: [Elecraft] Frequency Counter

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

RE: [Elecraft] Frequency Counter

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

Re: [Elecraft] Frequency Counter

I can recommend the M3 FPM1 Frequency Counter and Power Meter.. http://www.m3electronix.com/fpm1.html 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.

RE: [Elecraft] Frequency Counter Probe not working S/N 5567

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

RE: [Elecraft] Frequency Counter

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
