Agreed, it has to be antenna. If the new truck has shock-mounted mirrors there may be no bond to ground if that is where the antenna mounts. the coax needs to bond to metal at the mount or the SWR will be way out. SWR affects receive just as much as transmit.

Turn up the RF gain all the way and leave it.

RF gain is basically how open your receive is. There is really no reason ever to have it down unless you are trying to hear only close stations to you.

If you RF gain is up, your mic pins my be oxidized, or mic bad.
Try a different mic, and or clean the contacts in the connectors.

Hi and welcome to FixYa,

Initially, the speaker of course has been checked?

Offhand, would partial schematic of the mic and speaker section help?

Galaxy dx959 will not receive. Speaker is working. S meter is showing incoming signal.


the over power doides may be blown. you should start there .they should be marked D-1 and D-2. you may want to replace them with diodes of a higher rating.

Radio transmits fine but the receive volume is way down. Can hardly hear it with volume turned up full.


If you have talk back in this radio.( you hear your self through the radio when you transmit) then its a good bet that the RX wire in the mic plug has broken off.

The mic switch is responsible for putting the radio into receive mode when you release the key. If the RX wire is broken, the radio will not go into receive.

Normally when this happens you have no receive at all no matter what, but you will have very low sound if you have talk back installed in the radio.

Because of this, if you have talk back in your radio, and the volume is faint even at full blast, its a good bet that its a broken RX wire in the mic cord or plug.

You can attempt to see if the break is at the mic plug. if it is, you can re solder it and it will solve your problem. If you have no clue, then you can just go buy new 4 pin mic.

Cb is Keying Down instead of keying up when trying to talk


if you are transmitting fine Don't worry about the meter. Get an external SWR meter, they are better anyway.

Also, make sure the the switch next to the meter is all the way up on s/rf setting. thats for signal power and receive strength.

We have 6 sx600's we use in our store. 4 of the 6 when you push the talk button just makes a beep sound and you cant talk or anything! Why?


Beeping when pressing the PTT can be a sign of low or bad batteries. To check to see if this is the problem, move a battery from one of the working radios over into one of the problem radios and see if it solves the problem. It takes more energy to Transmit than to receive, so your radio may receive transmissions, but not be able to transmit. If this is the problem, replace your rechargeable NiMH battery packs. Charge the radio completely (always with the radio shut off. Batteries have an 18-24 month life expectancy.

If this does not solve the problem, check your chargers. Clean the battery contacts and charger contacts with a pencil eraser. Replace any non-working chargers.

They should allow you to trade your radio in for a used rebuilt unit if you call Delphi directly.

One radio makes loud tone when other radio transmits


You may have a defective radio that has a bad push to talk switch which doesn't mute the receiver and feeds back audio to itself or this could be a bad solder connection or a broken wire inside.
Not much you can do except replace it or have a tech look at it.
