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.

Cobra 148 GTL, Firestik II 2' tunable tip, Firestik K 74 lip trunk mount. I can't get a good match. SWR is in the red.


did you try sand paper. where the mount meets the metal you should sand off the paint to get a good ground. If that doesn't work try a longer antenna.

RED SWR ALERT LIGHT COMES ON WHEN I KEY UP


In most cases if the mic works the common cause is the transmitter in the mother board is shorting out or not soldered to the board properly. another cause could be that your antenna is too close to the CB and will disrupt the signal.

Self adjusting SWR does not work on 959 Galaxy


the swr on the radio is not what you are thinking it is. You have to set the SWR to anything below a 2.0 and the meter will let you know when and if your swr gets to high.

Galaxy DX 959. SSB doesn't seem to work. The power meter needle moves in AM but not in SSB. I tried adjusting the bias between test points 7 & 9 to 50 mA via VR12, but can only get it down to 90...


on ssyou are some what familiar with working on radio's. just make sure before you pull your hair out aligning the radio that you made sure it definitely is not tx on ssb. b the.Mic gain will increase the modulation. it could just be a meter issue. confirm this by having some one on another radio on ssb the same channel listen for you. if he cannot hear you then the ssb is blown out.sounds likelike

Can't talk about 2 miles ,swr is good


If your talking at least 2 then it sounds like it is the antenna. Any antenna should talk 10-12 miles on a good day, no matter what radio you're using. So I'd get a second look at that system.

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.
