Galaxy dx 2547

Have you tried turning the mic gain up,and not knowing Texas star model numbers,is it a mobile linear,if so,do you have a sufficient power supply?Just some thoughts off top of my head.

They are soldered by wires. no snaps. and will not interchange with cobra they have different ohm values. they can be order though. they are only a few dollars..

do the lights dim when transmitting? if so probably needs replacing if not there's nothing you can really do as far as i know but replace it.

Some possible issues may be a miss aligned receive section or a possible bad component in the receive section.

From my experience, Galaxy radio's have a much quieter receive, as were the cobra 29 seems to be a bit more loud, with more background noise.

The cobra 29 still has one of the best receives out there. There may be louder static, but it picks up amazingly.

If this radio had a clarifier it would be easy to tell if the receive was off. You could just tune it as you are receiving, and if it got better as you tuned it off center you would know. Otherwise you would have to open the radio, and adjust the receive by ear, which is something where you may do more harm then good.

The proper way to align the radio requires the use of a watt meter and volt meter, which are easy to come by, but as well you will need an oscilloscope, which is a more expensive piece of equipment to own.

If the unit is new, then it's under warranty. Contact galaxy, see what they say. Their tech support is pretty good.

But ALL in ALL,

If the unit seems to be receiving on freq, (no muffled or distorted receive) and it is working well besides having a less sensitive receive, then I would say it's just that radio.

I have a galaxy base radio, and it has a real clean quiet receive, but my cobra 29's seem to have a more sensitive receive, but I like that galaxy because there is less noise.

Hi, my name is John. Check your power supply, should be about 13 volts. hope this was helpful...

This is a common problem with a lot of Galaxy, Cobra and similar radios. It usually occurs from one of two things the radio has been operated on a higher voltage than it was designed for ( Called Volting) and has damaged the LEDS or it can occur from poor connections to the display board either the 8 Volt line or the Grounds check for the proper voltage at the display. Note if you ground your meter somewhere besides the display ground you may get a correct voltage reading but still not have the correct voltage reaching the display so be sure to ground your meter at the display and read the voltage there as well.

Check the ground. Make sure its grounded well on bare metal. To see if the ground is bad, or not making good connection, disconnect the antenna and turn it on. if it does not power up, that means your ground is bad, and it was grounding only through the antenna.

Make sure not to key up with out the antenna connected.

Had fixed the same problem yesterday. My cobra worked when it wanted to, when it didn't it looked like you explained. I found out that on my cobra the blue wire on the mike connector was broken. When it disconnects, no sound. after soldering, everything works fine.

do you have boots powering up the signal that can do it

For the money,the Cobra 29 nw/st is just as good if not better than a Galaxy. Cobra is more durable by far. I have had 3 of these cobra's in the last 30 years. Only had to replace the last one because the tractor got hit by lightning.
Sure would not pay big money for a name.
