First off, sorry to tell you, but you can not set your swr with your radio's swr cal knob. Trust me, I own a cb shop and know what I am talking about. I have been working on cb radios for years.

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 microphone 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 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.

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!!

SOURCE: Fresh install SWR will not come down

I try to use the center channel of where I'm going to be talking the most to get my swr the lowest ( ch.20 for all 40),but sometimes you can't so try to remember this; if it's low on 1 and high on 40 it needs to be shortened if it's high on 1 and low on 40 it needs to be lenghthened.

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.

Your power output has blown, they are called your "finals" they can be replaced quite cheaply.

I have a connex cx-4300 hp cb it will receive but won't send how do I fix this problem


Is there any RF being transmitted, to a nearby radio. also does the TX/RX led change.

There are many scenarios on this..

Loose/cold solder joints on the board.
loose diode on solder side of the IF area..
Bad RF transistors from High SWR..

if you can provide more info.

WHEN I KEY THE MIKE THE NEEDLE ON THE RADIO GOES FROM 3 TO 1


every day? can you add more info.. the more noise on the RX end will make the needle higher then the TX setting so if this is a noisey day and you have 3-9 s-units on the rx yes a needle will drop. without having a watt meter to see if your power is dropping when you TX is different.. add a inline watt meter and make sure you have a decent power source. and TX and see what it is showing for wattage. if it drops then check power supply first make sure its giving enough amps. then next chk swr's and radio..

Could you please tell me what COLORS that i need to put where when wiring a Superstar DM 452 to a Galaxy Saturn base station radio?


Don't worry about colors. look a the mic switch connections. one wire will be a common ground for TX & RX the middle wire would be ground(pin1) the n/c side will be RX pin4 the N/O side will be TX.... the same for the audio element side, one will be ground and the other will be audio pin 2.. this works for any mic and any radio.


pin1 ground pin 2 audio, pin 3 TX, pin4 RX.. standard pin outs cobra / galaxy/connex exports

Put another **** on 29 ltd and lost key up and receive but it still lights up. What you thank is wrong. 5 different mics, all work in my other radios. I heard something chatter and it would not tx or rx...


Check to make sure that there is noting shorting out inside of the radio. some mic plugs can turn from overtighting the mic connector.. also check the pins they may be broke or compressed too much and won't make connection to any mic.. Pin 1 is ground and pin 4 is rx.. take a jumper wire across those and see if you get rx back. same for tx pin 3.. jumper pin 1 and 3 should have a key up. pin 2 is your of course audio. these should be first things to check. cobras unidens and galaxys, connex, genlee etc. are wired the same. midlands and radioshacks ge are different. so make sure your mic is wired for a cobra or galaxy also.. any mic will work on any radio. as long as is it wired to it correctly....

Poor sending and recieving


Make real sure that you have a good SWR for your antenna system. ( No higher than 2;0 to 1 ). To do this it will require an swr meter. A meter can be purchased at any CB Shop that sell finer products. If the SWR's are good, then you probably have a bad final or driver transistor in the Radio.
Good Luck
