Check the Swr on the antenna system. N

Just type in GOOGLE (search) "STANDARD HORIZON GX3500" it has owners manual in PDF format.

hello unfortunetly not as these radios are resonating on the marine band which is vhf high band cb band is resonating on 27mhz ,marine band 157mhz so will not work .

Did your speaker wire detach somehow? You could have blown the voice chip. Do you have any transmit or receive at all? You may have blown the final transistors in it as well. Check the antenna and make sure your SWR is 1-1:5 and no higher than 2. Good luck.

I have a GX1255S (black) that has a blown voice chip. Everything else works fine. Sounds like you might have a stuck up or down button on top of your mic. If you would like me to send the whole radio to you, I will. You can reimburse me for shipping and a few bucks for my troubles if it works for you to switch the mic or put some of your guts into this radio. Just a thought. I was planning on taking it to the electronic recycling event in April. [email protected]

Open circuit on the PC board, open resistor on the board, fuse or possible bad on / off switch.

There were four coaxial cable connections. One turned out to be bad. Once redone, the signal picked up loud and clear

you will have to solder a female plug to those wires then you will be able to plug in a 1/4th male plug from your speaker wires

you can get this at any radio shack store you will have to order them but they can get them for you.

HI...

Yes you can fix this issue your self..

trouble shooting steps as follows

If it possible open the Radio..

then find out the contacts of Volume button..

Just solder two small wires then refix the Radio

Once you have fixed turn ON and short circuit the wires to increase the volume..

if you have any clarification let me know..

there are too many posibilities to your question the best thing to do is to have it checked out by your local two-way radio service center.

This radio has stand up if boards. These boards see to creat cold solder joints in them and the come loose from the main board. I suggest you resolder all the connections on the stand up boards and I'de guess the problem would be corrected. Good Luck
