What does Delta Tune do on a CB?

Your Citizens Band radio includes an array of controls for receiving, adjusting and listening to audio from other CB radio users. The radio’s delta tune knob, also known as the clarifier control, reduces the amount of static present on the radio when communicating with another person.

How do you squelch on a CB radio?

The higher you turn the squelch, the stronger the incoming signal will have to be in order for you to hear it. This has no affect on the receive as indicated by the meter. Turn it higher (to the right) to only hear strong signals. Turn it down (to the left) to hear weaker signals as well.

What makes a CB Mic squeal?

An audio feedback (squeal) is caused when the speaker is located to close to the mike and the talkback function is set to loud. The more sensitive the mike the worse the audio feedback. … It is normally caused from the radios own signal re-entering the radio and effecting the mike amp circuit or the transmitter circuit.

How far will 25 watts transmit?

For example, a 25-watt marine radio will roughly have a maximum range of 60 nautical miles (111 km) between antennas mounted on tall ships, but that same radio will only have a range of 5 nautical miles (9 km) between antennas mounted on small boats at sea level.

What does Cal mean on a CB radio?

antenna testingSR/F for normal operation, SWR/CAL for antenna testing.

What does the RF gain do on a CB?

Noise interferes with signals and it comes from the atmosphere, other nearby channels that overlap slightly, and environmental surroundings. To counteract noise, RF gain acts as a sensitivity filter. It reduces noise in the receiver without reducing reception power as a CB radio squelch does.

What is HI cut on a CB radio?

Hi-cut removes high frequencies to improve audio quality with SWR calibration of antenna system for maximum performance. Antenna warning indicator and receive/transmit indicator with automatic noise limiter reduces vehicle interference.

What does SWR mean on a CB radio?

standing wave ratioThe term “SWR” means standing wave ratio. A “SWR” meter is used to measure how well the transmit power signal emitted from a transceiver (radio) is traveling through the antenna system into the atmosphere. Checking and setting the antenna is critical to overall performance of transceiver (radio).

What does a CB Power MIC do?

CB Microphone Features Power – Power, or pre-amplified, microphones require a battery and amplify the audio before it gets to the radio. This is useful for those who speak softly, or may have a weaker signal.
