[Elecraft] K2 Frequence Drift

[Don Wilhelm]

Jason,

The K2 specification for drift is less than 100 Hz from a cold start at 
25 degC.  50 Hz is well within that specification.

I would suggest you do the dial calibration procedure after the K2 has 
warmed up.
I highly recommend the procedure on my website www.w3fpr.com - article 
on K2 Dial Calibration.
I would suggest a 15 minute warm-up period is about right.

73,
Don W3FPR

As we continued our conversation I found that when I turned on the RIT and listened on 7.218.95 he sounded "on freq" again.  When I questioned him about it he told me that he thought I was off freq as well.  I turned off the RIT and tuned to 7.218.95 and he told me that I was right on freq again.  The drift was obvious and stopped exactly .05 down from where we started.  I switched radios and we continued our conversation on 7.219.00.  When I turned the K2 back on and transmitted with it the exact same thing happened as before. As the radio warmed up it drifted down .05.
