HFSSTC potential damage to sensitive electronics .

[PowerTech]

It is safe to run 10MHz ~300W HFSSTC("plasma candle"), if distance to PC, router, camera and RPI3 is about 1.5-2m ?
This will be my first tesla coil, with no grounding(not available), and I don't want damage any devices nearby.

I'm not a expert. So please check and listen to others answers.

Some opinions. If saying about a self-oscillation plasma candle from maybe like aliexpress / ebay. I have one of that. The GND of that circuit is connected to power supply V-. I notice there are a cheap LED lamp in my room that is about 2m~3m away from this circuit was effected by EMI. It was blinking or out of control. I was confused because I think the radiation power of this ins't that strong compared with those huge tesla coils. But besides it I didn't find otherthings are broken or interrupted then. More safety suggestions you have to get from others.

300W continues noise will likely show up as noisy pixels on a camera, once you get too close. A PC would properly start to reboot.

I have not seen damages, only interrupted operation, to household electronics.

10 MHz is out of the range for some of the comparisons and within some other figures in my article on grounding and EMI for Tesla coils: https://kaizerpowerelectronics.dk/tesla-coils/drsstc-design-guide/grounding-circuit-protection-and-emi/
