Default Icom M45 VHF radio issues

My 2001 icom M45 seem to be giving me some issues. I hear a lot of engine noise when receiving now. Also the squelch has to be turned all the way up. At times its so bad I have to turn the radio off because I can not get the static to squelch at all.

I have not been able to find a warranty term in my paper work. Does anyone know if its still covered after 2 years? Also if its not, is it worth buying another ICOM M45 to replace it. Its flush mounted so if not another M45 it would have to be a bigger model to fill the hole.

Thanks
Steve

I honestly think that it is a problem with the installation and not the radio. Try using a grounding wire or shielding the wires going into it. Just my 2 cents

It may be a bad antenna connection or corrosion inside the antenna. Can you put an emergency antenna on the back of it and check it out before you dive into wiring or ship the radio out?

Thanks for the replys guys. I have a bit of technical sense and felt it was an antenna issue too. Although I have not cleaned it yet, I will do so next.

As far as installation, I bought my boat brand new and had the technician at the marina do the installation. Its been fine for the fist two years.

I find as the radio warms up, it gets worst. Thats why I am afraid its toast. I would think it should have lasted longer than 2 seasons.

I'll try cleaning all the connections.


Thanks again.

Still looking for a reply on ICOM's warranty though.

Try disconecting the antenna, and if the noise goes away the problem is in the antenna.

Next I would look closely at the power feeding the radio before I sent the radio off.

Could be a bad spark plug wire on the engine or alternator.
Is it a whining noise or popping noise?
With your engine off do you still hear it?

Take a small jumper cable and ground the outer shield on the antenna and see if the noise is still there.

If you take your antenna off and the noise goes away means that you must get rid of the noise at the source (probably engine) because you won't be able to suppress the noise out without hurting your received signals.

Have you checked the water in the batteries? Just a thought.

Have had the same problem with mine, even after rewiring the boat completely. never had the problem with my standard and seriously thinking about putting the old standard back in. Nitice if I turn on any electronics Bottom machine, radar etc, this happens. With just the motor running and no electronics on I dont have the problem. Thinking i need to put a filter on the radio wiring itself thinking it might correct the problem. If you do please post it. good luck-

I had a similar problem with my radio. (Icom, might be the M45 not sure) I had the problem from day one. Boat is a 25ft Pontoon brand new with a new radio and used antenna.

I tried a filter from Radio shack, did not change it.

I ran new wires to the help from the battery, was 16 gauge in the harness with in line fuses, and I put in 6 gauge, to a fuse block and ran everthing from the fuse block. I have not had a problem since.

If the problem is not in the antenna, try running new wire straight to the battery.
