Seem we're talking SSB - I have a question you guys can help me with!

 

A yacht I'm looking at buying has the main SSB box right next tot he Raymarine Course Computer. Would having them this close cause issues?

Should those wires be attached above so they don't flop around?

Yes, very likely, especially on transmit. SSB's "leak" a LOT of RF, and its pretty common for issues while transmitting. Often the  AP will go off course, the instrument panel lights (and sometimes NAV lights or others) will come on or blink while transmitting. Most issues can be dealt with with proper cabling, ferrites, and shielding.

Try it - call Taupo Maritime while on AP.....

Oh, and Kevin, Nope, no channel 16, not portable, much more complex than a vhf, requiring a ground plane and a decent antenna (often the backstay). They are not plug and play, and need some time, effort, and dedication to learn to use properly. Not worth it for the casual, coastal sailor. Oh, and when transmitting, they suck the power up too..

This happens frequently with SSB radios?  All Brands and models?

Yep what island time said.

There is some serious power that goes through HF radio sets ..and antenna matches.

To give you an idea  ...the HF radio should be direct connected to its battery..via a suitably large fuse...(you will see this in most manufacturers installation notes) ..unless you are running a 12 volt microwave an HF is probably going to pull more power than anything else on the boat (all be it for a short time)..

and most antenna matches have stickers inside saying "Do not open when transmitting as serious burns can occur"  !!

.

  and auto pilot black boxes are a bit sensitive.  Most manufactures of these bits of wonder ask that you not install with wiring running parallel to other electrical installations..

   You may get away with it ...till one day you get a bit of an earth problem or a corroded shield in some wiring... :eh:  :eh:

Then it becomes a nightmare to work out where the problem is coming from ..

 

Newer nav systems can be very tech heavy ( the last system I put in has a chart plotter connected to nmea 2000 and 0183, wifi and internet connection, that then uses the out puts to drive a large screen connected to a mini black box computer running opencpn. ...and even opencpn has a full radar overlay running on it......)

Best not tempt fate .

as the song goes...

"Ya gota keepem seperated......"

Thanks all, if we get to sea trial, I'll get on the SSB and call Taupo Maritime Radio while on AP and see what happens.

 

I think I'll plan on moving the SSB if we get the boat, as those are two important systems that you want to rely on when everything else is going wrong! I could just imagine trying to talk to Taupo Maritime Radio mid medical emergency and the boat turns 90 degrees every time you transmit! That wouldn't help the situation much.
