[Elecraft] Frequency counters for Alignment

[Arie Lukkassen]

David,

You need a better reference the XG2 is a great small crystal based signal generator based. But what is the reference? It all comes down to your targeted accuracy. Also keep in mind when you connect the XG2 to your counter the "pull" effect can easily adjust a few Hz.

Zero Beat with a reliable broadcast station is still far better or ask a instrumentation shop to calibrate. An other alternative is to use a calibrated transceiver but my own experience with this that the large amount of RF energy can easily overload circuits and then your reference makes no sense.

I have a couple of frequency counters, and I know they are a little off. 
  When I went through the alignment the first time, they tell you how to 
adjust settings based on zero beating from another transceiver, but I 
wanted to calibrate one of these counters well enough to use one of them.

I have a XG2 that I haven't built yet, and I see that it has a +/- 1khz 
accuracy.  I was thinking of using that to at least get the counter (a 
Heathkit IM-2410) close enough so I don't have to use the other 
transceiver.  The XG2 will work ok for this won't it?
