Q) Why have an RF Gain control?
- This switch is an on/off control for the RF Gain, which controls the receiver sensitivity.
In normal use, this switch should be set to DX (distance).
If switched to local, and if the RF gain control is turned down, you will only hear very local signals.
Q) Why have a Mic Gain control?
- In the "olden days" CB's had RF gain control so that if you were receiving interference from a strong signal on a nearby channel, you could turn the receiver sensitivity down and get rid of the interference, while still (hopefully) being able to hear the person you were speaking to.
Nowadays, there are fewer users on the CB (and double the number of channels there used to be), and modern CB's are much better filtered so the chance of getting such interference is much less, so the need for the RF gain control isn't really there anymore.
Q) What do the quick up and quick down buttons do?
Q) Where is the CB's speaker?
- In the "olden days" of CB, power microphones were very popular with users, in an effort to make their transmitted audio louder than standard.
With these mics, there was often the need to turn the transmitted volume down within the set (although the mics usually had/have a volume control also), in order to avoid "overmodulation" (distortion).
Nowadays, most CB's use a different type of microphone insert, and power mics don't make that much difference (except add distortion if turned up too far) so the need for the Mic Gain control is not so great.
99.9% of people will be best suited to having the Mic Gain control turned up fully.
Q) Can i still talk/listen on the CB when the CB is in PA mode?
- Like most CB's the speaker is on the underside.
Q) Does the PA facility have a volume control
- No, switching over to PA disables the receive and transmit functions of the CB, so instead of being transmitted, your voice comes out of the PA speaker at high volume!
Q) How do you change the Frequency Band to the UK band?
- Yes, the CB's main volume control acts as a volume control for the PA, allowing you to adjust it so that you avoid feedback but still get a good loud sound.
- 1 ... With the radio switched off, press and hold both the "AM/FM" and "SCAN" buttons whilst turning on the radio
2 ... After the radio switches on, let go of the held buttons (you have to take your fingers off the buttons as soon as you see all the segments in the display appear) - the current frequency band code will show on the display
3 ... Select the UK code by going up or down through the available codes with the channel knob
4 ... Press the "AM/FM" button to confirm and store the selected band code
If you go abroad, this is the procedure you should use to choose the apprpriate frequency band for where you are travelling.
