Question about Connex 3300 240-Channels Base CB Radio

2 Answers

Static restricting RF signal while rolling down the road but stops when i apply the brake or when i slow down to stop or when I am sitting still. I drive a truck for a living which is an international, i have tried running a ground wire from frame to antenna, running power strait to batteries still no luck. This static pegs the needle on the meter half way across. I also installed an 1500w antenna oil cooled coils.

Are you using the factory coax. A lot of Internationals have a terrible setup from the factory, they run the coax into a junction box and run your cb coax and your fm radio out of it. You could be getting bad rf feedback through from the FM radio. I would next try a regular antenna mounting bracket setup with a good stranded center coax with at least a 95% braided shielding. You have been on the right track, most problems like this is a process of elimination. If this doesn't fix the problem, or you already have this setup, please reply on here or email me at:

I would be more than happy to assist you with your problem.

You're getting RFI coming from the Trucks main control module or one of the auxiliary system's control modules coming into the radio THROUGH through the antenna. This one is going to be tough.

08 Buick lucerne cxl. Third brake light works as well as front signal lights. No rear brake lights or turn signals. Tail lights and headlights and third brake lights works. Bulbs good. Help


Stop Lamps
The brake pedal position sensor is used to sense the action of the driver application of the brake pedal. The body control module (BCM) provides a 5-volt reference voltage and low reference to the brake pedal position sensor. The position sensor provides an analog voltage signal back to the BCM that will increase as the brake pedal is applied. When the brake is applied, the BCM will then apply battery voltage to the left and right stop/turn signal lamp supply voltage circuits and the center high mounted stop lamp (CHMSL) supply voltage circuit illuminating the stop lamps. At the same time the BCM applies battery voltage through the signal circuit to the transmission control module (TCM) and the engine control module (ECM) indicating that the brakes are applied.
Ground for the stop lamps is supplied as follows:
• G402 provides ground for the left rear stop/tail/turn signal lamps
• G403 provides ground for the right rear stop/tail/turn signal lamps
• G301 provides ground for the CHMSL
The stop lamps on this vehicle will not illuminate unless the ignition is in the accessory, run, or crank positions. When the ignition is in the OFF position the stop lamps will not illuminate when the brake pedal is applied.
Battery voltage from the LT TRN/SIG and RT TRN/SIG fuses located in the rear fuse block is also used by the body control module (BCM) for stop lamp operation.

Turn Signal Lamps
Battery voltage supplied to the body control module (BCM) from the fuses listed below is used for turn signal and hazard lamp operation.
• LT TRN/SIG fuse for the left turn signals
• CTSY/RF TRN fuse for the right front turn signal
• RR TRN/SIG fuse for the right rear turn signal
When the turn signal switch is place in either the LEFT or RIGHT position, ground from G300 is applied through the turn signal switch signal circuit to the BCM indicating the turn signal request. In response to this signal, the BCM applies a pulsating voltage to the front and rear turn signal lamps supply voltage circuits cycling the lamps ON and OFF. At the same time the BCM sends a GMLAN serial data message to the instrument panel cluster (IPC) to cycle the appropriate turn signal indicator ON and OFF.
Ground for the turn signal lamps is supplied as follows:
• G104 provides ground for the left and right front turn signal lamps
• G402 provides ground for the left rear stop/tail/turn signal lamps
• G403 provides ground for the right rear stop/tail/turn signal lamps

Where should I have my rf gain selector hi or lo


rf gain is about local coms if you want your cb to RX far away stuff set it too high but local stuff like friends family that are local then you want too set rf gain to low then only local signal can trigger the squelch ... so the radio will ignore the static and only trigger you when needed ? see what i mean rf gain ye a DX guy will set it high or too listen to people like over 50K away
and let then break the squelch...min

How do i stop the intermittent static?!


Static can be caused by a poorly charged or bad battery. Try cleaning your battery contacts with a pencil eraser, on the battery, radio, and charger. Then recharge the batteries and see if the problem still exists. If so, try a battery from a known good unit and see if it stops the static.

If the battery is not the issue, you could simply have environmental noise. RF (radio frequency wave) in the environment is a common problem in urban areas. If you are using the radios in or around computers and other electronic devices, coil the cords to these devices and make them tidy. RF noise can be emitted through the cord like it is an antenna of sorts. Coiling will reduce this effect.

If your radios have PL capability, aka private line code, interference eliminator, turn it on, or change the setting. This should block out unwanted noise and interference.

Best regards.

When i try to stop in the snow or rain my brakes kick back and make a funny noise and i can't stop at all. only when i use booth feet


Those are your anti-lock brakes. Either there is a malfunction, or you are applying to much brake for the road conditions, which is causing the anti-lock brakes to activate. If the road conditions are slick and hazardous, slow down and start stopping sooner.

Windows wont roll up and down and hazard continues to click even when not on.


These are two separate issues.The most common cause of the clicking is the hazard switch located above the radio.Replacing this generally takes care of that issue occassionally it is a malfunction in the turn signal switch but most likely the hazard switch. If all windows are affected would check fuses first.If the windows roll down from the corresponding switches example rf allows rf to roll down. If not suspect an electrical issue such as fuse or relay.If they do roll down from the switches on the doors but not the drivers door possible a master switch issue.Drivers door contains a master switch that controls all windows.Do the windows work at all?

URC-9910 remote: The RF part for this remote stopped working.


I have the same remote as yours and occasionally the RF remote is not working due the interference signal from outside or next door at certain hours.
My suggestions:
(1) To relocate the receiver and reposition the anntena for better reception of the RF signal from the remote unit.
(2) Replaced the battery.

Hope these help!
