Have you got one steco? They have a bit of a rep for building cardboard handhelds

You'd hope the fixed stations would be better?

Had one in each of my last three boats.... never had a problem

I've got a dead Icom lying in the garage and another dead Icom in the garage.

What I have found useless is those little rubber aerials

As a general rule the electronics themselves work fine. They sell well because they are cheap. They probably do an OK job in the shelter of a yacht cabin. On an open boat where they get constant spray though the reputation (and my experience) is that the casings aren't build as well as the big names in the marine VHF market and so you will inevitably be replacing it at some point. Hopefully the damage comes at a convenient time...

My experience with the h/helds was so bad I didn't even consider them for my fixed station. I'm fairly sure that one of our other moderators tried a fixed station that leaked!

Your experience is relatively unusual from what people post here over the years. When people have had issues with SH and Icom they have usually find that they get sorted easily.

Can you trace fault to gubbed antenna? ICOM should be able to supply a replacement.
Miscellaneous - Icom UK

To clarify. The rubber antenna was one of the after-market things mounted on the "A" frame for a fixed unit. It worked but it's performance was just pi55 poor.

I suspect both the Icoms had a hard life but they were mounted inside cabins on boats I bought and were dead when I got them. One had front panel knob seized solid and the other just doesn't transmit.

I think a big part of reliability issues has to do with installation, and to be fair you won't get away with exposing the back of any fixed set to the elements. I do try to fit them where the front also gets a bit of protection and seal the mounting surface.

The Cobra hand-helds I have are really cheap and nasty but I've had them for years and they still work. I doubt they would survive a ducking but it's better it's than nothing.

Do you have ferrites on radio cables ?
Not sure how much it helps but mine SH have them in standard.
Mount them closest to the radio and secure by tape.
Without tape they will go down.

The interference comes to your radio 2 ways , either via the power cable or via the co ax cable
You first need to determine which is the source

switch on the radio with the engine running and with the interference noise on the radio, and disconnect the aerial coax. If the interference stops then the interference is coming via the co ax, if itís still there its via the power line.

You can eliminate the power line as a source by trying running the radio from a standalone battery separate from the boats battery


You will need to determine the route of the interference by using the above method before you try and eliminate it, otherwise you could be wasting your money going down the wrong route
