Hi Mike, I had to perform the temp compensation a few times. A couple of those times necessitated a retry due to operator error in the setup :-) I eventually achieved a level of proficiency in preparing to apply the heat source. Initially, I used a hair dryer the first couple of times. But the drift was still present. I then used an incandescent light bulb (60W I believe) in a small articulated desk lamp. This worked much better as the temp rise was more consistent over a longer period of time. After that successful calibration, I have yet to see any drift or be called out for having drift by another ham.
The KX3 temp compensation is brilliant for a fanless rig once it is calibrated correctly. regards, Brian VE3IBW On Thu, Feb 28, 2019 at 9:07 AM Mike Parkes <mspma...@gmail.com> wrote: > The other day I finally got up the nerve to perform the temp compensation > procedure on my KX3.
