Yes I agree and I'm sure I had trouble getting it like the OP, before going unshielded. I do have beads on it at both ends which might help. But I did that from start so it might be fine without them too.

cheers,
Nick.

Re: SSB Advice

No it is not. The OEM cable is an OPC-566 and available from West Marine for a hefty price and includes the connector to plug into the radio pigtail connector. A shielded cable has an outer uninsulated conductor that completely (or nearly so) surrounds the inner conductors. It may be in the form of spirally wrapped strands or inter-woven braided strands. You would connect this conductor to the ground screw at the back of the radio.

OEM cable is available at Radioworld for $75. West Marine should meet that price.

Re: SSB Advice

I wonder if wrapping the trailer wire 3 or more times around a ferrite choke at each end would serve as well? Just a thought.

With the proper core this can be extremely effective. I (and others) have posted with ferrite advice, here's one of my recent posts: Weather Fax on SSB

Re: SSB Advice

http://i1-news.softpedia-static.com/...okes-are-2.jpg

google ferrite chokes their are 100's

So the wire harness joby does the job but is more expensive than doit yourself by people who know what they are talking about.

Got to buy a book! I get depressed when I see all the connection ports on the back. But definitely want to get weather information. One step at a time. 17 months 25 days to go.

Re: SSB Advice

The shield only needs to be connected on the radio end, leave the other side as it is.

The cable isn't shielded; I have used ferrite cores like described in this thread. Shielded cable would be better.

ciao!
Nick.

Re: SSB Advice

You can always use shielding braid that is sold separately and then slid over the cable. Not as tidy, but it works.

So Nick the control cable from the Icom 710 to the AT130 should be:

4 core shielded cable. Follow the wiring diagram that Icom provides. What gauge wire for this control wire? Something that can handle 2 amps?

link the shield to the ground on 1 end only. either end?

Run a ground wire from the radio to the ground on tuner as per Icom instructions.

Dont think I will find fancy solutions in our small hardware stores so the separate braid is probably not going to work.

Add kiss to At130 ground point.

Coaxial set up like any co axial set up.

I must be close now

Steve
