- `set af <value>`
**Parameters:**
-- `value`: Airtime factor (0-9)
+- `value`: Airtime factor (0-9). After each transmission, the repeater enforces a silent period of approximately the on-air transmission time multiplied by the value. This results in a long-term duty cycle of roughly 1 divided by (1 plus the value). For example:
+ - `af = 1` → ~50% duty
+ - `af = 2` → ~33% duty
+ - `af = 3` → ~25% duty
+ - `af = 9` → ~10% duty
+ Yyou are responsible for choosing a value that is appropriate for your jurisdiction and channel plan (for example EU 868 Mhz 10% duty cycle regulation).
