Richard,
Drift was seen on the KX2 digital display, and indicated by concomitant
very mild audio distortion from being slightly off frequency.
I am perfectly willing to accept that I may have just been getting a small
bit of RFI, but was just curious if anyone else has seen this behavior
before.
Are you talking about the output frequency as measured on another device?
Or the numeric readout on the radio's own display?
I've seen shifts in some situations on 2m, which I think was RF getting
into it. If you turn off Mic Up/Down button control maybe it will help
there.
I've had issues where
That was my thought, too. Dang, that is excellent frequency stability! The spec
is "+/- 1 ppm typical at 25 C after 5-minute warm-up."

1 hz? My hallicrafters crystal controlled oscillator was rated less than 400
hz an hour drift after warm- up (it will do much better than that after 1 hour
of warmup), That was considered very stable in 1962. I still use it in short
qsos where I barely hear 10 hz of drift in 5 minutes, after
ONE Hertz??

Not directly. I was outside, but under a pop-up canopy.
Thanks and 73,

All,
I have KX2 s/n 2862. I noticed while operating Field Day that, about
every 15 minutes, it would drift down 1 Hz. Has anyone else ever seen
this in their KX2? I will admit it is possible this was just the effect
of RF getting back into the rig, but at 10W, I'm not really sure where
