Mine drifts too as you know - but it equates to a slight turn of the dial for me. It can go for about 10 minutes before I need to slightly adjust the dial. It's like I am chasing the signal. My 1957 Zenith FM radio I listen to all day 5-6 days a week in my office never drifts. I only have to touch the adjustment knob when I accidentally bump it.
The SX-43 FM drifts to the point it is disruptive for listening to while I work as I am getting up every 10 minutes of so to adjust it. The other bands (AM, long wave, SW) are all stable and pretty much stay put reasonably as well as my other fleet of SW radios.

The FM drift on my SX-43 officially is on my bucket list to solve.
