    thank you for your help!! the coax is new just made up at the radio shop rg-8 with new connectors....only thing i did not have was a ground ******** the radio. i added the strap did not help....coax checks out with DVOM meter...... swr checks out on three different meters ..it does recieve doesnt seem great ,but talks like a monster!! on a bird meter at the radio shop turned all the way up, it would dead key 100 watts and swing 220...will i hurt the radio by using it?? can a regular old radio shop be able to adjust vr9 vr2 or vr15 correctly?? or should i send it to a reputable place to fix it? i havent tried the rf light trick but i will..just dont want some idiot with a golden screwdriver working on my radio....thanks again for your help!!

VR9, VR2 or VR15 may just be out of adjustment. This does assume you are transmitting signal and recieving.

It might not hurt to check with second SWR meter.

Depending on location, there is only a tiny possibility of residual capacitance causing this. However you might want to put a few neon bulbs around your base to monitor for stray RF. If there is stray RF, they will light up- no need to connect them to anything, you can tape them to convenient places you can see. If they do light up- check coax connectors- which you should really do as a routine anyway, and check coax for damage. Then add a flat braid strap ground to "earth bond" for the radio. Which you should have anyway,

    Tuning/completetly aligned. would help the reception. Whether it would help the key up flickering is debatable, but with the added information, it seems most probable at this point the issue is minor and likely in the radio itself, perhaps little more than humidity in the relay, or lint- the contacts may be arcing on key up. I would double check the quench rectifier, should be D7 and also check D5, D6, R16 and Q2 as they are in the relay coil circuit.

    Any decent shop should be able to handle the tune up. The bigger issue is the reception, but that may be influenced by where you have the predator set up and how it is pointing. and if the people in the shop know you, it helps a lot.

SOURCE: coax length

the shorter the better between radio and linear, all coax has to run in 3 ft, 18 foot is recommended for all antennas.

I have a galaxy dx 99v2 18 ft coax hooked directly to ball on my 102 wip and spring ,3ft jumper to swr meater all grounded to battery and power directly to battery tryed to set SWR and pegeing out


first of you have to set the SWR on the radio first . then some liniers require you to run low wattage and others high wattage . the SWR is what you have to control by keeping it low . You must take into consideration the length of the coax plus any jumpers you have . You say you have 18 ft of coax plus a 3 ft. jumper ,thats 21 ft..You should keep that jumper as short as possible ,like 12" . plus you should make sure the antenna is grounded good , like to a good spot under the vehicle . 102 " whips are supposed to be almost perfectly tuned for a good match .

I am having a problem with mt cb. I used all new coax, antenna, antenna stud and mount. New mic and radio. The problem is I hook up the swr meter, keyed and the meter swung hard right. I have changed


ok, you have a high SWR.. this is what you can do.. you're gonna need to check the Radio's coax connection to see if it's loose on the Radio itself.. you're gonna have to open the Radio cover on the speaker side.. now go look at the connections on the pc board itself and see if there is a possible broke connection.. one is pcb ground, and one for the center. also, you might want to get a phillips head screw driver and gently tighten all the screws on the pc board. becareful going in there.. after this said and done, check the antenna connector itself to see if it's loose. if so, then you're gonna have to a pair of pliers to turn the nut on the inside while you use wrench to hold it in place on the outside.. now you're ready to test the radio.. don't put the cover on just yet until you see the results. set up your SWR Meter to the Radio and then set up the dummy load and do a SWR Test. if the reading is good, then the Radio is all set.. now for the Antenna.. you said that it's all new, but regardless you need to test it too.. check both ends of the cable and do a condinuity test.. get a ohm meter that has an audio sound. this will help you.. set the meter to ohms/conditnuity.. then short out the probes to get a ZERO reading/audio sound.. now take one end of the of the cable and put the probes on the connector.. one probe for the outter ground shell and the other probe to the center pin connection. if you see a ZERO reading or an audio sound, that means you have a short in the cable.. another way is to do it end to end.. put one probe on one end of the cable, and the other probe on the other end.. test the ground side first.. if you get a sound or a ZERO reading, that means you may have a short in the cable itself and may requier to remove the connectors.. some cases you might have to replace them.. remember to calibrate your meter when testing let me know how it goes.. I'll continue to help you.. you can contact me on Facebook.. https://www.facebook.com/pages/ANR-Communications-Repair/136358796473669?ref=bookmarks Good Luck..

Got it peaked and tuned and hooked up a new coax and mirror bracket and my swr is at 4. Before I did all this I had the stock coax and swr was under 2. What do I need to do to get the swr down?


The antenna needs to be tuned. The reason all of a sudden your SWR is a 4 when it used to be a 2 is, after a peak and tune, the radio is putting out more power, there for more RF energy is being reflected back into the radio. That is why the antenna has to be tuned.

It is important to tune your CB radio antenna to the proper length. The length must exactly match the wavelength of the frequency you transmit on. Or be really really close.

All Cb antenna's have a way to adjust the length of the antenna. If it's a mag mount, the metal whip can be slid in and out of a metal collar. Usually a set screw. If its a fiberglass whip, the way to tune it is on top. It either has a small metal rod with a set screw to adjust the length, or it threads in and out to adjust length.

Either type you have it will need to be adjusted for proper length. Here is how to tune the antenna to lowest SWR.

Some radios have a built in SWR meter. Some do not. If yours doesn't have an SWR meter, then you have to use an external SWR meter. Radio shack carries one, and you can find them cheap on ebay.

If you have a built in SWR meter or external, the procedure is the same:

1. Turn the radio to CH 20.(This is the center of the band.)
2. Switch the meter switch to CAL. (CAL stand for calibrate.
3. Key the radio. (Important. Do not talk while keying the radio.)
4. turn the CAL knob up until the meter hits the CAL mark.
5. Now while still keying the radio flip the meter switch to SWR.

Where the meter falls after that point is you SWR reading. If its above 3, that is real bad. 2 is not gonna kill your radio but its not the greatest. 1.5 and under is a good place to be, but the lower the better.

If your SWR is high, Here is how to find out if your antenna is too long or too short.

1. Turn to CH 1
2. Repeat SWR procedure. You must calibrate every time you do it.
3. Remember the SWR reading.
4. Turn to CH 40.
5. Again repeat SWR procedure.
6. Compare the reading between CH 1 and CH 40.

Now if the SWR is higher on channel 1 then channel 40 your antenna is too short. You must make it longer.

If the SWR is longer on channel 40 then on channel 1, then the antenna is too long, you need to make it shorter.

Make height adjustments about an eight inch at a time, and take reading each time.

once the SWR is significantly lower and the reading on channel 1 and 40 are about the same, you a about matched. At this point turn the radio to the center of the band, channel 20 and take an SWR reading.

You should now have a low SWR reading, 1.5 or under. If you are 1.5 or under, you are good to go.

If you cannot get the SWR to an appropriate level, there may be an antenna problem.

Cobra 18 wx st receives-wont transmit


Take the cover off, flip it over solder side up, check all solder joints for cracks, cold solder joints, check the safety diode where it comes in the radio, before I go further, can you pick up the weather channel?...Does the PA work?...need to check the pre-driver and finals,audio chip, hook up the power meter using a coax three foot jumper from the output from radio to the input of the watt meter, then the antenna, first check the SWR, on the scale on the meter to cal/swr mode,adjust it to spec, then while still keyed down turn the dial to SWR,if it is the safe range your ok,then turn the Dial to 10 or 20 watt scale and key the mic. Does it have any wattage? If not suspect the finals, they are located on the back rail, if it does have RF then its the audio chip, its located on the right side rail facing you,closest to you.remove it and replace it with same ....hope this helps....

Hello 64driver,

Make sure the radio is grounded properly and that the SWR is around 1.2:1, 1.3:1 is good but try to get it to 1.2:1. Also take a power output reading while keying the mic. To do this with your power meter put it in-line with the CB and your antenna and key the mic you should get about 4 to 5 watts PEP. If this is the case your unit is putting out the proper power level, if not have the power amplifier checked by a qualified repair shop.

I hope this helps

SWR calibration waaay off the chart


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 microphone1.gif 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.

Cb radio


When you asy that you have an swr meter, you are refering to an inline meter, not the one on the radio, correct? Have you set the SWR by the instructions of the inline meter (if that is what you have)? Have you made sure the antenna is mounted to the bracket with the white plastic washer in between the antenna and the top of the bracket? You have checked the antenna coax for a broken center conductor and for a center conductor shorted to shield with a multimeter? Check antenna bracket to ground with a multimeter?

double check your connections and your cable for shorted PL 259 connectors. Oil filled antenna! Humm Sham on you if you are using a liner! Oh and quit sniping the antenna remember the higher in frequincy the shorter the antenna and longer for lower in frequincy. So it could be just where the antenna is located some antennas work good there but a diferent one wont try another spot also make sure your in a clear area when checking SWR not your drive way next to the garage or house or other car and finaly use an external SWR meter the ones on the radio some times SUCK.
