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 .

SOURCE: CB transmission

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

SOURCE: refurbished dx 959 from galaxy no modulation? no transmitt?

If there is no transmit at all, it sounds like it wasn't fully refurbished. If it is just low modulation then just turn VR16 and VR14 all the way to the left.

If its not working at all, send it back. It hasn't been refurbished.

SOURCE: power meter on my dx-979 barely moves off of 0

Well,some meters are set different than others,to see what is going on,you need a good WATT-SWR meter,but that is not a bad reading of SWR, you can get one at Radio Shack. You can not go by the meter that is on the radio,it,s probably not set right. hope this helps..

SOURCE: I can't get the swr value close to 1 it's over 3 what am i mising

Several things are working against you.
1 Antenna location= Needs to be in CENTER of car or truck, and high. no grounded metal can be next to the element (the hot/positve part of the antenna)

2 the only way to really ground the antenna is by having a flat metal ground plane under the antenna. DC grounding does NOT do this, that is a misunderstanding.

3 make sure you use a tunable antenna. I have found the wilson's to be very easy to tune and performe very well, for a base loaded antenna.

4 in short a wilson or k40 magnet mount placed on the very top of the roof in the center will have a perfect ground plane. Then shorten or lengthen the steel whip to ajust your SWR's. You will get the best results this way. This is the ONLY way to achevie good performace.

5 I will say this the absoulte best antenna is the 102"steel whip, if you got the clearnce and dont mind it hitting tree limbs put it on a big magnet mount with a spring at the base and youll have a perfect antenna. But the wilson is shorter and easier to tune.

Measure out your coax in 3ft intervals. Like if you need 7ft use a 9ft length of coax. Also make sure your mirrors are grounded use a external swr meter as well, the internal swr on the galaxy could be off. .

you have no power because your radio is not tuned to your antenna.You get a new radio and put junky coax and a decent antenna and you expect it to work right. Get 75 ft of rg-213 and you will see a change.

When i unkey my mic, my swr lights come on. sometimes they flicker sometimes the dont, what is wierd is sometimes they stay on for a seccond or two and the meter show full


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,

I have a cobra ltd 29 bt hooking to a 102 inch whip and cannot get m swr readings down under 3 or it will go up higher then the calibrate triangle instead of down. my antenna is mounted with a gumdrop...


  • Sounds to me like you need to check the connectors and connections on that coax. A cobra29 and a 102" whip is a simple enough set up and should not produce that high of SWR unless the coax or the connectors on the coax are pretty messed up. Also i recommend putting an SWR meter in line.
  • The meters on them Cobras can be accurate sometimes but I trust an inline meter much more.
  • Ground it again to make sure.

I have a Midland 1001Z 40-Channels Base CB Radio and a Magnetic-mount CB antenna. 29" stainless steel whip and 6" spring. About 46" high overall. All bought from /www.thesource.ca in Alberta...


Try Grounding it better. Its supposed to equal 8.5 ft.(102 inches) but the coil may make that in all.You can clip like 1/8 inch off at time until it goes 2.1 Swr. Thats a good standard. 1.5 SWR is desired. If it don't have a coil with it that may be the problem. You could turn it into a 8.5 ft. antenna by buying a 102" inch whip to screw into the base of your antenna, it depends if it holds or not. You could build you a matcher like this with a solder gun+solder and 2 resistors. Get you a box with 2 female cb antenna inputs. Drill a hole for both Cb antenna inputs into box. Place them into holes screw nuts down snug. Run a copper wire inside to both grounds or a plate somewhat. Run a thick gauge copper wire from center cb ANT INPUT(2) to other input of ANT INPUT(1). Solder 2 100 ohms in parallel from input to Ground. If you could take apart your radio(eliminating the box idea). Just Solder 2 (100 ohm) resistors to your Antenna output then put it back together. 50 OHM MATCH HERE Is the main idea. I've used 75 OHM Tv coax and reduced SWR.

I have a galaxy dx 959 I had a connex board put in it sometimes it sounds great then the next time it sounds destoreded or a loud sweel


did they put both the power ground and the audio ground together when they installed it? some echo's can only have the one ground , not both.. either the power wires ground or the coax ground on the audio wires.

also check the swr's..

check SWR's check to make sure ALL coax connectors are tight. and if still doing it. may be loose connection in board. but the export style radios go crazy like that when coax is loose or have bad grounds. due to there floating ground circuit design. there not the same as a cobra were its case is ground.
