Put the band switch on Lo, and the band dial to D/A, then you are in the CB band.

You may want to pic up a frequency counter for that radio. It will make it a lot easier to figure out where your at.

in older connex 3300's you cannot disable the talk back. Its part of the audio chain. If you disable the talk back you will loose your audio. There are 2 things you can do.

Hook a relay to the speaker so that when the radio key's id disconnects the speaker. (Big pain, not worth the trouble.)

The other will not disable the talk back but it will stop any squealing.

Use a noise canceling mic. An RK-56 will work great. You will get no squealing with that mic.

The proper setting depend on what you are doing with the radio at the time.

Hi, my name is John. Take the cover off the radio. You will need a soldering iron and solder. You can purchase at Radio Shack. Plug the solder iron in and let it get hot enough to melt the solder. Solder where you broke the ground, also check around the circuit to see that no more damage was done. replace the cover, remount using shorter screws, enjoy. Hope this was helpful..Rate this solution on the four thumbs-up. Good luck.....John

You can. Just wire a switch in between the resistor, and the solder point.

The center wire doesn't do anything. Its the outer wires. You can get a standard CB plug with 2 wires that will work just fine. If that plug fits, I it will work. My concern would be if the pos and neg are the correct sides. It should be, But I wouldn't know unless I looked at it.

DO NOT HOOK the radio up with the power wires backwards. Or you will blow the polarity protection diodes. They are there to blow if the radio is hooked up backwards.

If you look at the plug. There is a side the goes to a point, and the other side is square. The black wire, Ground, should be on the side that goes to a point. If it does, then that plug is standard.

It's fine to use and hook up in the usual way. Do not hook up the center wire. It does nothing in the radio. You can clip it, and put a bit of shrink tube on the end as so it does not have a chance to short on anything.

If you are not sure about hooking this power cord to your connex, just go on ebay, and get a regualr CB power wire. They are cheap. It should only have 2 wires.

Hi radams58

I have seen this one before and it can be aggravation I recommend replacing the the plug on the wire and in the radio so it will be less of an issue in the future. I have gotten where I almost hate an export power plug for this reason. I would be sure that the local cb shop can supply both of these items at a reasonable price.

Have your antenna checked at a place that knows what they're doing. If your antenna system is bad, ground problem,coax bad mount or maybe just a wrong or bad antenna. Then the sounds not getting out the antenna and its feeding back thur the radio.If your echo board was bad then your radio wouldn't transmitt at all.
If you unplug your external speaker will it squeal? If not do the antenna and if that reads fine just try a better speaker like a uniden 20watt speaker.I own a CB shop and this is easy to fix.

Connex 3300... | Answered on Jul 20, 2010

First off you can by any radio parts that you need and any good CB shop knows that.But if its only a little over a year old then you can send it back to factory and it'll be fixed free. There is a serial number on the back of the radio the first to digits is the year and the second two the month it was made so is a year or a little over a year old if so call 1-814-898-1046.

This radio are know as what's called 'export' radio. They are imported under the auspices of being a 10 Meter Amateur radio and then through a typically easy modification are made to allow the selection of US CB channels. usually the modification involves plugging in a loose connector inside the radio radio chassis and/or removing a jumper wire soldered to a circuit board. If there is a nearby CB Shop they will usually do this for a modest fee.

Keep in mind that a radio needs to be Type Accepted by the FCC to be legal to use on the CB band in the US and export radios typically are not. Be sure to check the rear label for an FCC ID number.

About the easiest way to install a fuse would be an inline AGC 5A fuse/holder from your fuse panel, or IDEALLY a direct connection to your battery. Your radio (Tx) outputs 7W, so a 5 amp fuse would be plenty.

In case you require it, here's the owner's manual for yur unit:


Hope this is helpful.
Good Luck!

If you're wanting to talk on your basic 40 channel then a/d and on high band. Always keep your mic gain and rf gain to the right echo I like both around 10 o'clock. nbl at the top.talk back is up to you if you want to hear yourself and run it on high power unless you're running a power box then switch to low power.
