The Weather and SubGhzD apps are supposed to decode AM modulated common signals, like weather stations or rf remotes.
You can check the currently supported protocols here: [baseband/fprotos](https://github.com/portapack-mayhem/mayhem-firmware/tree/next/firmware/baseband/fprotos)
**This program is sensitive to signal strength**, so if you set values too high or too low, it will not be able to decode.
Ideal values are around: AMP 0, LNA 32, VGA 20. If still nothing, play with these values, try to reduce or increment.
Common frequencies:
- 433.92 MHz (EU)
- 315 MHz (US, Japan)
- 868 MHz (EU + others)
