KX2 Drift During Field Day

Ian, NV4C
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
enough would come from to cause an issue.

Thanks and 73,

Ian, NV4C

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

Thanks and 73,

Re: KX2 Drift During Field Day

 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 an one hour warmup.

How soon we forget!

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 I knocked the dial before. Oops.

Re: KX2 Drift During Field Day

Ian, NV4C
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.

Thanks and 73,

Ian, NV4C
