+Change furi_hal_subghz_is_frequency_valid and furi_hal_subghz_set_frequency_and_path
+
+Reminder, the unofficially supported freq are 281-361 MHz, 378-481 MHz, and 749-962 MHz
+
+281000000 - 361000000
+378000000 - 481000000
+749000000 - 962000000
+
+```

+
+Don't forget to add your new freq to the user settings file (and change ignore_default_tx_region: false to true)
