If your radio suffers from an unnaturally high background noise floor even with no antenna attached, your internal RF gain baseline is set too aggressively. Navigate to . Note your default number (usually ~86).

Before changing any value, write down the default number.

Adjusted to ensure the radio outputs the factory-specified wattage (typically 12W AM carrier, 30W FM) into the dummy load.
