Do it in the lazarette. The icom Atu is extremely well sealed and keeping the ground plate and antennae routing as short as possible Is a more important consideration

Steve,

 

I learned a lesson here with the speakers. I found some great sounding 4” DC Gold speakers with good bass but the speaker magnets were so powerful they threw off the compass and I sold them on eBay. I shopped for a long time and finally found a really great replacement pair with magnetic shielding that did not impact the compass. The best part is they sound awesome with a good range and are not too expensive. They will almost fit in the existing cutout from the original speakers. You will need to file the hole just a little bit bigger and drill more screw holes. You will need to fill the old holes with something like MagicEzy. MagicEzy - Cream is a really good color match. Other than that, the fit is pretty close even though they are round.

 

Here is a link:https://www.fusionentertainment.com/marine/products/speakers/ms-fr4021

 

I have had these for about 4 years and highly recommend them.

 

 

With best regards,

 

Mark

Dean, 
My only worry with using the engine starting battery for the Icom is the negative ground. 
The radio will be grounded  onto the plate located by the rudder and the power to the radio at the engine. 
Not sure what this implies.

Hi Nick,
That’s great information. I’ve always hated trying to get that smoke back inside the box!

There are some isolated DCDC converters available which would produce 30A each, so like your system, two would be needed. I don’t much care for the faililure mode you describe. As you say it’s the high voltage that would have blown up the caps (probably electrolytic or tants), and probably some IC’s would not take kindly to overvoltsge, so the fuse would do nothing.
If the same thing happened with a 24V bank being connected via failed DCDC Convertor, to a 12V battery, the first thing that would happen is high current flow, and the fuse would do its job.
The other thing I don’t like about running two DCDC converters go directly power the Icom is the possibility for conducted emission harmonics to interfere with the RF signal. The converters will run switching in the hundreds of kHz, so it doesn’t take many harmonics to start interfering with the MF band.

Your story has lent weight to the the 12V battery based solution.

I could of course install a dedicated battery, and echo charger, but the engine battery is right there begging to be used. I’d change my engine battery to a deep cycle type, but other than that it’s a simple and elegant solution.

Hmm, where’s the gotcha?

Hi again NIck,
Where did you locate the M-802 Transceiver Unit?

If somewhere around the chart table area, do you have any RF interference issues with the long signal cable run from the chart table area to the aft lazarette?  Did you have to install any suppression measures?
I suspect there is a dedicated conduit run for this cable but I've  used it already for my solar cables. (I've just realised maybe that additional unused conduit was meant specifically for SSB!).

Re: Cockpit Speakers 4"

Hi Steve,

I replaced our outside speakers with a pair of low magnetic field marine speakers from Poly Planar (I think).
There are lots of them out there. They don;t affect the compass at all.
The biggest issue I had was finding ones that weren't too big to fit the existing holes.

Re: Antal main outhaul car for 1999 Super Maramu 2000

Steven Bode - SV Intention 1994-SM#117
 

Hi, Ken.
I had the same issue earlier this year. Yes, Antal changed the track size. I had to replace the track for €457. Your Mainsail is probably not set up for this, but I've seen some mainsails that are fitted with a block on the clew to provide a 2:1 purchase. Makes it easier on the electric motor and rigging. More importantly, that car (Antal 4110/SH BB CAR 110 WITH SHACKLE) was never designed to be a clew outhaul car according to the engineer I spoke with at Antal. It's a traveller car where the force is directly vertical. The Amel system puts undue stress on the car, pulling it at an angle causing it to fail. So, at some point in the suture (when I replace my sail or the current car explodes), I plan to replace my car with the Antal Outhaul system. See: http://antal.it/ENG/SYS0052_en.
Not trying to throw you off, just give you more information to make smart buying choices.

Hi, Mark.

So, I don't get it. What was stupid about this post that I don't understand? I need to replace my cockpit speakers as well and was just about to pull the trigger on the DC Gold 4" speakers. They're no good? What did you end up doing? Can they be wrapped in shield or something?

Re: [Amel Yacht Owners] M801E HF/SSB Radio power Supply

ngtnewington Newington
 

Hi Dean,
On Amelia we have the M802 SSB installed by Amel. They chose the DC converter route: there are two Mastervolt 20A converters in parallel. 
These are located under the chart table in the little locker.
There is a breaker to power them up by the chart table porthole.

Is this a good system?

Amel decided it was the way to go. However Mastervolt do not make a 30A version to make your 60A supply. 

Secondly: if the Mastervolt fails and allows 24v direct to the Icom then damage will occur to the radio. An in-line fuse would not blow because only the voltage would be up not the current.


If you use your engine starting battery, and then charge it from the 24v domestic bank with a Mastervolt Magic series 20A it will 
1. be less expensive
2. Be safer for the radio from a power supply basis as even if the Mastervolt failed, and allowed 24v direct to the battery, that would protect the radio. Although there would be potential for damage from applying 24v to 12v battery.

 Why am I worried about Mastervolt DC converter failure? 
Because it happened to me. When I bought the boat. The surveyor powered up the SSB at the breaker. Smoke poured out or the Icom box! I checked everything and one of the converters failed and sent 25v to the radio. Burnt various capacitors etc within the radio. I had it fixed and bought a new DC to DC converter. However I have asked myself whether this is really a good system ever since. I am now paranoid.
So if I am not using the SSB much I disconnect the power supply from the radio then power up and check the voltage is 13.5v before plugging it back in.

So not sure I am helping much. 
Other considerations;
galvanic isolation
Radio interference

Hi,
I am planning a new installation involving an Icom M801E HF Radio (which I already have). The unit needs to be powered from 12V and the specifications call for up to 60A. (This is double the power consumption of the M802 radio used by many North American cruisers. I have a support ticket lodged with Icom to confirm that there is not a mistake in the specs!).

I wonder if there’s anyone in the forum who has installed the 12V version of the M801, who could share their power supply installation details..

Options would appear to be:

1: High power (60A) DC-DC converter(s) running from the 24V bank. (Isolated type is preferred, which means two units in parallel are required, although I’m not convinced this is absolutely necessary).

2: Tap 12V power from upper or lower half of house bank, connect house bank mid-points and install a battery balancer. A bit ugly really.

3: Install isolated low power (10-20A) DC-DC Converter between house bank and engine battery and power SSB from engine battery. DC-DC Converter replenishes battery in slow time and alternators provide bulk and eq charge. I like this option from a low-noise perspective. Nothing else is connected to this battery, and if conducted emissions are a problem from the DCDC converter, just switch it off. And in the event of an unforeseen/unlikely complete discharge event, there are another 12 batteries available to start the motor/genset.

4: Others?

Many thanks
