Where should I set my fr gain on my 949 just got tuned and peaked doesn't seem to be working correctly


Dustin turn the rf gain knob all the way to the right also make sure the much gain is atleast half way. If.your still not hearing anything than you need to have the antenna tuned. Swr. Is very important do not use the radios meter to set this it is done with an external swr meter.

How do you calibrate a uniden pc68xl which has a built in swr meter but no calibration button?


That is not a built in SWR meter. The meter on that unit only measures S which is signal strength and relative transmit power.

What is Dead Key on a CB Radio?


Deadkey is slang it is CW or Carrier wave which is RF power produced before modulation/audio is mixed in which stimulates PEP wattage slang being SWING WATTS. A Watt Meter is used to measure it which is often a combination device Wattage/SWR/Modulation meter.

Red lights come on tx n rx and antenna come on when I key up the cb radio and the swr meter doesn't move


if a mod has been done to the cobra 29 (all 29,s)the light will come on just find vr6 audio the radio as it comes on adjust vr6 untill it goes away,,,,always trust your watt meter(s.w.r scale)over the flashing light its really easy to do it beats paying a shop $10-$15

How to set swr galaxy dx 949


you do not "set" swr.you cannot set it on the radio. the radio can tell you what yourswr is. it can take an swr measurement. swr has to do with the antenna system. in order for the radio waves to radiate from the antenna properly, the physical length of the antenna must match the length of the radio waves. if the antenna is too long or too short you will have a higher swr ratio. the higher the ratio the less energy will leave the antenna. but that energy needs to go somewhere, so it goes back into the radio which causes damage and can ruin a radio.

first turn the channel to 20. then switch the meter switch to CAL. then key the radio. while keyed, turn the CAL knob up until the needle in the meter gets right to the CAL Mark. next flip the meter switch and key the radio. where ever he needle is, is what your swr is.if it is more the 1.5 that's getting high. if its over 2 you are in the danger zone. if its over 3 you are damaging your radio. you must repeat the calibration proceedure for every channel.to figure out weather your antenna is too long or short, you compare the swr readings from channel 1 and ch 40. if the swr is higher in 1 then on 40 the entenna is too short. if its higher on 40 then 1 its to long.

My ANT light comes on when ever i push the mic button but my SWR isnt that high


The meter will be more accurate and an external meter will be even better. If they show good disregard the ant light it is adjustable. It may have been set to sensitive from factory. These erroneous SWR reading can be the side effects of a PEAK & TUNE if the coils have been spread but that should also show on meter.
SWR meter calibrations
  • Switch (S/RF SWR CAL) to the CAL position.
  • Push and hold mic button
  • While holding mic button adjust the SWR CAL knob so the meter needle swings to the CAL mark on the meter
  • While still holding down the mic button, set the (S/RF SWR CAL) switch to the SWR position, to read the SWR reading. Note: When switched to SWR position the meter needle should ideally be as far to the left as possible. Anything over 3 is not acceptable.

I want to know the correct method on how to do a SWR test with the Galaxy 959.I have a 5 foot self adjustable firestik and have mounted it to a 4mm thick aluminum plate 30 cm square and will have it higher...


The best way is with an antenna analyzer but that is too expensive unless you do SWRs for a living. The meter on the radio should suffice for your needs.
Adjust the screw on the antenna until it is about 1/2 inch out.
Place the srf/swr switch to swr.
Go to channel 1 and note the SWR reading on the meter.
Go to channel 40 and do the same.
If channel 1 SWR is higher than channel 40, then screw the tuning screw out a turn or 2.
If channel 40 SWR is higher than channel 1, then screw the tuning screw in a turn or 2.
Repeat until the SWR on channel 1 is the same as 40. Channel 19 will be the lowest.

If you are not comfortable using the built in SWR meter, you will have to invest around $20 for a small SWR meter.

I don't understand how to adjust the SWR or how the built in meter works for my DX949.


Here is a basic instruction on how to adjust the SWR. When you adjust the SWR, you are not changing anything on the radio. You are actually tuning the antenna for best SWR. The lower the better. SWR stands for "Standing Wave Ratio" Or in layman's terms, SWR is energy that is reflected back into the radio. The higher your SWR reading, the more RF energy that is not leaving the antenna, and getting reflected back into the radio. This can cause damage to the transmit section of the radio. The length of the antenna is what will change this. The length of the antenna must match the length of the radio wave. The following instruction will explain how to take an SWR reading, and how to use that reading to ascertain weather the antenna is too long or too short.

Here is a quick explanation of the meter. There are 3 settings for the meter. SWR, MOD, and PWR. When you are not keying the radio the meter will show you your receive signal. How strong some ones signal is. When you have the switch on MOD and key, when you talk it shows you modulation. How much audio you are putting through the radio. When its on power, and you key the radio, it shows you your dead key wattage.

Tuning your antenna:

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 SWR
3. Key the radio. (Important. Do not talk while keying the radio.)

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.

Dont know how to use the swr meter on my radio


With radio turned on

1. Switch the first switch (S/RF SWR CAL) to CAL setting
2. Key mic up &
3. Turn SWR CAL knob while still keying mic until the needle is on the red CAL arrow at the far end of the meter scale. Unkey mic.
4. Switch the first switch back to SWR setting.
5. Key mic up again and record SWR reading and adjust as needed.
6. When done adjusting put switch back in the S/RF setting for normal operation.

Do not flip the switch with the mic keyed up.

My Meter Won't Move


weather can effect your meter .Those meters are not very accurate just a base line get a good swr meter and then check it.If your getting good radio checks it could be the potentoimeter is dirty . Radio shack sells contact cleaner and lube try cleaning it . That might help
