Peak and tune connex cb radio

SOURCE: connex 3300hp radio

First off, sorry to tell you, but you can not set your swr with your radio's swr cal knob. Trust me, I own a cb shop and know what I am talking about. I have been working on cb radios for years.

You must have an inline swr meter, which can be purchased online or from a truck stop. The ones at truck stops are cheap ones, but will do the trick for the most part.

You connect your antenna 18ft coax to the antenna plug of the swr meter, and a jumper coax (any length) to the transmitter plug of the swr meter and then to the radio.

Close all doors and make sure no one is messing around with the vehicle or antenna. You must be set up as you would normally be transmitting.

Now set your cb radio to channel 40 and your swr meter to fwd. Key up your microphone and at the same time turn the set knob on the swr meter until the needle is at the line that reads set. Unkey your mic and set the the swr meter to ref. Key up again and note what your reading is. Now leave the swr meter in ref and turn the cb to channel 1. Key up and take your reading. If the reading on ch 1 is higher than ch 40 you must raise the stinger on your antenna. If ch 1 is lower than 40, you lower your stinger. You are trying to get lower than a reading of 3 and as close to 1.5 as possible. If you lower your stinger as far into the antenna as it will go and you need it shorter, you cut the bottom of your stinger no more than 1/2" at a time, and recheck your swr reading after each cut.

Once you have gotten the best reading you can, connect your antenna directly back to the radio.

The setting your swrs is to make your antenna as efficient as possible, by trying to get it as close as you can to a 50ohm impedance. THE ONLY PART OF YOUR SYSTEM THAT CAN CHANGE YOUR SWR IS YOUR ANTENNA, not your coax and not your radio.

On the swr meter, the fwd/ref switch stands for forward (power that is being transmitted out) and reflected (power that is reflected back into the radio.

Just for information sake, the swr cal switch on your radio is used to set the meter to reflect the swr that your antenna is set at. The meter on your radio is like a dummy light on your car. ONCE AGAIN, YOU CAN NOT SET YOUR SWR ON YOUR RADIO, only the antenna!!

i have the same radio turn talk back off and there is enough power ull have talk back through you trucks radio speakers and it needs to be hooked up to the battery with at least 12ga wire

They probably still have more experience then you do! You should be okay as long as you tell them that you just want a basic peak and tune. Nothing crazy. If you ask for super mod of some kind then you will end up with a radio with problems.

You can also send it out to have it peaked and tuned.

50 watts isn't bad tho. I have never worked on a connex and don't know much about them so I couldn't tell you who to peak it out.

The Cobra 29 has always been a good talking radio and is preferred by truck driver mainly for that reason! The Connex is a great radio in it's own right but sometimes needs a little help. I would suggest a power mic and there are many to choose from but Astatic is a clear winner! My two cents for a suggestion!

The best way to set it is to get you a radio check, go to channel 19 and ask someone about three to five miles away to give you a radio check, start with your modulation all the way open and go from there.....hope this was helpful...
