My Connex 3300 the Recieve is going out I can here will close but thats it.. Antenna, Coax, SWR's are fine..... Could it be the recieveing ship in it going out or what???

first thging to check is you swr get it as close 1.5 as you can if its to high this could be your problem could be as simple as tuning your antenna or installing good mini 8 coax 18ft long only run 1 antenna and make sure antenna is grounded good thats where i would start if that dont work take radio to a reliable shop like communications unlimited in hebron oh have them check it but a good reputable shop not joe blow hope this helps

check your swr

sounds like a bad ground try moving your antaneas maybe or if you have wippes or firesticks tries trimming then

You will need an SWR meter to check your antenna. FIRST.
I would find help at a local cb shop.. They SHOULDN"T CHARGE to help you SET the swr. only if you need a part or something ..
I don't charge to SET SWR"s .. only if the cust needs a insulating washer or another antenna, or new coax, so-239 etc... I would be glad to help you.. let me know if we can -- CB Shop Temple, TX

There is a good chance you could have blown your final transistor. It could also be something is no malfunctioning in your mic. Is it on frequency? Hook it up to a frequency counter and make sure channel 19 reads 27.185. If it is your final transistor it blew for a reason. Most likely it got hot from a high SWR. 1-1:5 is the goal and no higher than 2. If it he SWR is higher then 2 the check your coax cables and adjust your antenna. Good luck.

Hi jeremy, my name is John. Welcome to FixYa. I think you are saying you are trying two different antenna,s. With the big one, sounds like you have a high SWR. or a bad ground. Make sure that your antenna is grounded good and nothing is blocking it. You will need a SWR meter and a three foot jumper to check this. How to check this is take one end of the coax jumper and run it to the radio and the other end to the meter where it is marked radio. Now take the antenna and put it in the other fitting marked ANT. Set the dial on the meter to SWR SET then turn off all your modulation,MIC GAIN, POWER MIC, now key the MIC and adjust the needle where it says calibrate all the way to the edge of the scale, not going past the edge, with the MIC still keyed up, turn the switch to SWR. that reading you see on the scale is your SWR. If it reads a three (3) or over, it is to high. Depending on your antenna, there are adjustments. Thanks for choosing FixYa...John

What sort of antenna are you using? Wilson, K-40, etc? Also, is the antenna right near any metal or perhaps you have heated rear glass (which means you have thin strips of copper in close proximity to your antenna).

Any of these things can cause enough impedence mismatch to cause your VSWR to rocket skyward.

have you checked the coax connectors? It's gotta be a bad connector,damaged coax or a defective antenna. Careful--don't test "too much" or you'll burnout the final amp!

You are using an inline swr meter to set your swr right, not looking at the meter on the radio? Here is the process to set swr on an antenna:

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 of 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. Your radio and coax can give you false readings, but only the antenna can actually change the swr.

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.

Hi,

Based on your post/description:

1. how do i set the swr
Normally SWR are calibrated on your operating channel (where you usually stand-by). This is to maximize transmit power and receive sensitivity. To set SWR, switch to channel of your choice, switch SWR control to CAL, key or press PTT, while pressing PTT rotate ADJ knob until max deflection of needle on meter, release mic, switch control to SWR, key/press PTT, needle reading/deflection is SWR for that channel.

I would suspect that your SWR will vary from your current 1.4. This is because you have too big excursion of channels (240 channels).

2.reading a 1.4
This reading is good enough and should do. However as earlier stated, you seem to have 240 channels which would mean that your radio + antenna moves in a wide bandwidth and since the antenna tuning is affected by frequency, your SWR will also be affected by channel.

Best if you can further lower it down.

3. some cb cant get me
This is because the standard CB radio is only 40 channels. The next would be a 80 channel and then 120 channels.

4. is it my radio
Yes, you have a wide coverage radio almost an extended 10 meter rig.

5. do i have to set my radio on high or low to set my swr
I will assume you are referring to power output, set it to HIGH when doing SWR calibration

Hope this be of some help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.
