Some small electronic devices react to PMR446 adversely temporarily, when exposed to a PMR446 transmitter, during the transmission.
- Portable DVD player: Green horizontal stripes on screen. Increasing if I hold the PMR446 transmitter near.
- Portable CD player (discman): Laser lens loses track, CD spins up very fast; also indicating low battery.
- Boombox CD player: Skips and noise hearable if too near to laser lens + fart sound at speakers.
- Standalone DVD recorder: Nothing, surprisingly.
- DECT unit: Display brightness decreases temporarily.
- USB Multimeter: Display lower current than actually flowing (e.g. 1.2A instead of 1.6a). Sometimes, voltage jumps up to 9.99V (highest displayable amount).
- CD boombox: Fart sound from speaker.
- Toy robot: Do random moves.
- Toy phone benign girl: Decreased speaker volume; ability to be enabled by the PMR446 signal.
- Portable standalone LED torch gets dimmed.
How can these interferences be explained technically?
