[Elecraft] Drifting Away...Does it matter?

[Dave]

Lee (and others)

In a perfect world, our transceivers would hardly drift in real terms.
Fitting a 0.5 ppm TCXO (e.g. Kenwood SO2) will reduce drift to negligable
amounts in a rig with a single master oscillator. My K2, with thermistor
mod, had a frequency drift of 13 Hz over one hour after a 30 minute warm up
on 29 MHz. That was in a steady ambient temperatur in the shack. That's darn
good for a rig with more than one oscillator that I built myself.

> I've been following the facinating discussion of Frequency Drift in the
K2.  A lot of work but some very bright fellows have gone into making the K2
a drift reduced rig.  I cannot say drift free, but as I understand it ... it
is close.

enough to make it matter.  I am a contester and do a lot of search and
pounce, hunt and peck, whatever.  There are times when I sit on a frequency
and run the dickens out the rig, but I am using the RIT and am constantly
changing the RIT to suit the signal to my old ears.  So, I've never had to
really work about drift.
