    I cannot get the SWR on my Cobra 75WXST to an acceptable level (constantly in the red on my meter). I have checked & doublechecked all my connection and find no problem. When I power up my radio I get a ground into my antenna (a "partial"ground) reading from my antenna tip to vehicle ground. I have moved my radio and power source - from a fuse box and a ground straight to the battery, same problem. Where is this "partial ground" coming from?

Do you have an SWR meter? Are you sure that the connector that screws onto the radio is soldered properly? If the ground is touching the center wire then it will hear but not transmit very far.

How do I tune my Galaxy DX 55v cb?Im getting out and people say they hear me clearly but I cant pull nobody in.I need help setting my knobs where they need to be.The cb used to be


Get or have someone Set the SWR's on your antenna.That is the first thing you should always do before even talking on the radio.. Check the antenna.

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

My antenna light stays on even after I have realeased the mike


Try checking the SWR's on channel 1, 20, and 40. The SWR's will change from the low channels to the mid channels to the high channels. The key is to make sure that the SWR's are around 1 or less at all three points. If the light goes out when checking one of them, then the problem is most likely the SWR's. If the light stays on when checking these channels, the issue might still be the SWR's but I would look at the grounding on the antennas. When holding the talk button on the mic and switching from calibrate to swr, can give a false reading. This is due to the calibrate circuit remaining open until you release the talk button. Take the SWR reading by releasing the Talk button on the mic after calibrating then pressing the talk button again after switching back to SWR. This will be the most accurate reading. From everything you described, I would be looking for a grounding problem with the antennas or coax, possibly even a rub though on the coax somewhere in the dash.

My radio is recieving a signal from other cber's but i don't think they can hear me


Go on a channel where people are talking and when some one stops transmitting key up and say, "breaker breaker, can I have a radio check please?"

that is how you call for a radio check to see if people can hear you.

breaker breaker, or break break means kind of like, "excuse me, I would like to talk on the channel please."

If they hear you the will most likey say, "its working." or "Checks in the mail." You can then ask them after that how the radio sounds.

Also make sure your mic gain is up.

If you get no response then there may be another problem. Make sure you followed the instructions that came with the radio on how to tune your antenna for best SWR. This is important.

The ant light and the other light light up red when i key the kic


the tx/rx liight is green when your radio is recieving signals and turns red when you are sending signals. the ANT light is red when your SWR is too high (over 3)

1. turn the knob labeled swr cal all the way counter clockwise
2. set the rf swr cal switch to the CAL position
3 key up the mic and hold it while you rotate the swr cal knob until the needle reaches the swr cal postition
4. set the swr cal rf switch to the swr position
5. key up the mic while on chanel one (record the the number)
6. switch to chanel 40 key up the mic (record the number)
if the number on chanel one is lower than the number on chanel 40 then your antenna is too long.

1) push the button marked S/RF / SWR / CAL to CAL

2) Hold in the button on the mic

3) Turn the SWR CAL knob until the needle is over set to the far right of the meter

4) flick the switch (in step 1) to SWR

Your SWR reading will be displayed. The more to the left the better..

Can't pick up or receive at all


Na. Hes probably got the RF gain all the way down. If it were an SWR problem he would see the red light, and people most likely would not be able to hear him, and he would hear other people.

Turn you RF gain all the way up and leave it there. There is no need to turn it down unless you are trying to not hear any one far away at all or on a fox hunt.

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.
