[Elecraft] Test Data on the temperature compensated KX3

[Doug Millar]

Hello again, 
    I did a couple of runs on the Kx3 with 50 seconds on TX and then reading the frequency drift at 144.000MHz.  Here is what I found out. My question is whether it is good enough for JT mode on that frequency. Let me also sat that the stability at the HF bands is very good. This is for 2meters. 

•     Usingthe audio counter as a reference•     Itransmitted for 50 seconds and recorded the drift over the next two minutes. •     Between10 and 50seconds it drifted 60hz on rx•     After50sec. the drift went to less than 1hz/sec. tapering off to little or no driftafter 1min 10sec. •     Thiswas done in ambient air at about 23deg C.    Testing done at 2w and .5w and tests at 12 and 14v input voltage showed no effect on drift. 
  I would be curious what others have found.
