What does a power mic do on a CB radio?
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. These microphones can be identified by a volume knob on the microphone (usually on the back) and/or a battery compartment.
What is the power output of a CB radio?
The current specification is simply “4 watts output (AM) or 12 watts output (SSB)” as measured at the antenna connector on the back of the radio.
How do I increase CB power output?
There are several procedures for ensuring maximum output.
- TUNE THE RADIO. A CB radio is only as good as the coax and antenna connected to it.
- USE CB-SPECIFIC ANTENNAS.
- ESTABLISH A GROUND PLANE.
- CHECK THE VSWR.
- ELIMINATE RESISTANCE.
What is SWR on a CB radio?
The 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 Delta Tune do on a CB?
The delta tune is the CB name for a very similar function on amateur radios called RIT, or receive incremental tuner. The Delta Tune controls the frequency your radio’s receiver is operating on.
Why is CB limited to 4 watts?
The FCC allows a maximum of 4 watts of output power for CB radios to avoid signal interference with other devices, such as TV and emergency communication radios.
Are CB linear amplifiers illegal?
Although the commission has eliminated many citizens band rules, such as the requirement that CB operators be licensed, it still strictly enforces the ban on so-called linear amplifiers, which can increase the power of a CB signal from the authorized 4 watts to several hundred watts.
How do you test a CB with a multimeter?
How to Test for a Defective CB Antenna
- Using your multimeter, touch one of the probes to the metallic end of the antenna.
- Touch the other probe to the metallic threads at the end of the antenna.
- As you maintain contact with both probes, measure the circuit’s resistance.
Can high SWR damage a radio?
Sure, it’s possible. High SWR can reflect enough power back into the radio to create enough heat to cook the final RF transistor. It isn’t usually an immediate failure, it takes some time for that heat to build up and do damage.
Is low SWR good?
SWR Range Explanations. SWR 1.0-1.5: The ideal range! If your SWR is under 1.5, you’re in great shape. If you’re at 1.5 and really, really want to drop down to closer to 1 it’s likely possible to do with addition tuning, different equipment or a different mounting location.
What does S RF mean on CB?
S/RF is the signal length, and it indicates the strength of the outgoing signal. “S” is the received signal strength in units of S. “RF” means the radio signal power, usually in Watts.
