Re: [Amel Yacht Owners] VHF issues

It is likely that all of the problems identified are related to the cable and/or their associated connectors than to the antenna itself. The coaxial cable runs up the inside of the mast and is subject to abrasion and aging issues. Further, there should be a cable connector at the base of the mast that connects the mast cable to the interior boat cable. This connector is necessary so that the mast can be removed without cutting the cable between the radio and antenna. Water can enter the cable thru abrasions or run down the cable in the mast and possibly corrode the terminal. We found that we had to replace ours six years into our circumnavigation.
Please also make sure that your antenna is electrically grounded to the mast and thus the vessels ground plane system which provides the other half of the antenna system. This is different from the battery ground. Glen and Julie Bradley SM 209 C'est Assez Author, Escape from the Ordinary, about Amel circumnavigation

Hi Dean;
FYI, per my discussions with Olivier, the antenna cable does not have a connection at the top of the mast. The only connection between the VHF and the antenna is at the base of the mast at the ceiling level in the forward starboard cabin. On Kokomo this connection has a heat shrink around it and when exposed looked new.
Happy Sailing;

We have a similar poor-transmit issue with our AIS antenna. It does not seem to transmit reliably but receives just fine. This symptom can often be related to a bad connection somewhere.
In troubleshooting, I switched the VHF Antenna and the AIS antenna, and the AIS problem disappeared. My conclusion was than my VHF antenna and cable run was good, but that my AIS cable was not good. (I did not attempt to check my VHF radio with the AIS antenna).
I eliminated the cable run from the chart table to the interconnection point at the base of the mizzen by connecting a temporary good cable from the AIS unit to the mizzen base connector (accessed via the light/toiletry-holder in the aft cabin ensuite shower). However the problem seemed to be further up the mast (probably the top connection I guess).
I have not attempted a repair at the top. In reality, the AIS transmit functionality is "acceptable" to me, the range seems to be a few miles, and the receive range is much more than that.
So, if you want to try and eliminate antenna/cable related problems, you could swap the AIS antenna into the VHF radio, and vice versa and see if the problem jumps to the AIS. Its better of course that the VHF antenna is on the main mast for height, but at least this gives you a check ability.
The 54 (mine at least) has 4 identical VHF antennas, two on each mast. However, the AIS and VHF Radio are probably the two which are easiest to swap for test purposes.

Re: [Amel Yacht Owners] Fie on Fi
Ryan Meador
Paul, Kelly and I also use Google Fi. We had the same experience. Except for a hiccup when I first activated my service (likely because I waited until I was in Bermuda to do so, instead of home), it's been great. We had flawless service in Martinique for over a month. On December 28, Kelly lost service. The following afternoon she contacted support through my phone, which still worked. The support person seemed to do something, and then mine went dead too. I'm curious to know when you lost access! We've been contacting support for many days and they refuse to tell us anything. It still works in non-French countries. Ryan and Kelly SM 233 Iteration Off the coast of Montserrat, bound for Saba

Re: [Amel Yacht Owners] Fie on Fi
Nowhere else in the world except Martinique have I had problems. It has been on/off. There is no alternative. All carriers rely on local towers. Martinique is the worst that I know of. If you had a local SIM, it is sometimes better because the local carrier gives preference, but I found it impossible as a non-French citizen to get. Can you imagine what we did and what it cost in the Caribbean before GoogleFI? And, what about everywhere else?

Fie on Fi
paul.cooper74@...
I just want to send out a word of caution to anyone considering switching to Google Fi for cellular telephone and internet. I think many are interested because of the advertised "seamless coverage in 147 countries." Well the old adage that if something seems too good to be true it probably is holds true here. My wife, son and I all have Google Fi for our carrier, and it was wonderful down here in the eastern Caribbean until recently. We had good coverage everywhere we went, including Martinique, and then all of a sudden in the middle of cruising with our sons, we lost all coverage, phone and data, while in Martinique. Since we had no phone or internet and were on the hook we couldn't get support. When we got to a wifi cafe, we chatted with Google and after many stock interventions, still had no service (this was 2 weeks ago). They said there was nothing they could do, it wasn't their problem, it was the local carriers. When we got Dominica service resumed but when we reached Guadeloupe (France again) it was gone again. Again I found some wifi and contacted customer support (not technical support, they don't seem to have that, only customer support). They had me do the same interventions which again didn't work. Again they said sorry nothing they could do and gave me a credit of $20. We are now back in Martinique and there is still no Google Fi service with no indication it will ever resume. We were using cellular internet for many things, including weather and email and phone was critical for organizing the numerous contractors working on my boat. Very inconvenient to say the least. We just got back from the local Digicel office where we bought a new plan and have put Google Fi on "pause." Can't speak for other parts of the world but it appears the whole google fi system hinges on the local carriers in the various countries, and the customer support person actually told me they had "no authority" to contact those carriers??! So feels like a house of cards to me and suggest you beware. Any one with lost coverage elsewhere in this watery world? Paul C. SM 238 "Maracuya" Martinique

Re: [Amel Yacht Owners] VHF issues

It is a good idea to pick up an inexpensive (~US$50) SWR/power meter to help trouble shoot radio transmitting trouble due to bad cabling and/or bad antennas. The digital ones will confirm the radio is transmitting at proper power, and on the right frequency as well as measuring the efficiency of the antenna system.
Some AIS boxes have a built in SWR meter that you can access via the computer interface. Bill Kinney SM160, Harmonie North Bimini, Bahamas

Re: [Amel Yacht Owners] VHF issues
Mohammad Shirloo
Hi Thomas;
Our issues were almost identical to yours. We had our entire cabling and antenna transmission/reception tested by three different techs at different ports. They all had the proper equipment to test cabling and antenna power transmission from the back of the VHF to the top of the antenna. All of their initial suspicion was the Antenna. However, testing would always show almost perfect transmission power. So, we always assumed an intermittent faulty connection somewhere, even though all connections looked brand new, or an intermittent fault in the Antenna since it is now 10 years old.
We ran into an old tech shop in Malta while hauled out. He pulled the VHF, took it to his shop and came back the next day and said that it was a filter within the radio, he had the part, replace it and it is now fixed.
We have not had any issues, that we know of, since. Had we not ran into the tech in Malta, our plans were to replace the antenna, then the radio followed by cabling, if necessary, to resolve the issue. It is not a good feeling to be out of cell range, without a reliable VHF.

Hello, we have also been experiencing intermittent transmission and reception issues with our main VHF iCom IC-M505, as we noticed that we had a better range with the portable one. We have conducted several inconclusive tests (with main and cockpit speaker, without phone/wifi interference), checked the wiring at the chart table, and the antenna ends.

Re: [Amel Yacht Owners] VHF issues
Thomas Peacock
We had a similar issue on our SM. Limited distances in terms of transmission (less than a mile), as well as reception. I assumed it had to be the antenna, but after much trouble-shooting, we figured out it was the radio itself (a Simrad, about 15 years old). A new radio fixed the problem.
One other place to check the antenna, however, is at the base of the main mast. I don’t know if the 54 is the same as a SM, but there is a connection there between the coax coming down the mast, and the coax coming from the VHF. Ours was somewhat corroded. However, fixing that did not help much. We bought a Garmin 300 and have been very happy. It has an “active” speaker that goes in the cockpit (a volume knob on the speaker), so that the helmsman can hear transmissions, but those below can sleep in relative silence. There is also a remote handheld unit that pairs with the nav station VHF for use without having to go below. Tom Peacock Aletes SM 240 St Augustine, Florida

Re: [Amel Yacht Owners] VHF issues
Thomas,
We still have the original Shipmate VHF installed so not sure how much help this thought is; we experienced similar issues a couple of years ago. We noticed in the Bahamas a vessel anchored within a few yards of us hailed the Exuma Land and Sea Park about 15 miles away and got a response. When we hailed the park couldn’t hear us (boats near us could hear our transmission).
After going through the same process as you checking all connections etc. I eventually replaced the antenna on top of the mast. This solved our problem.
With best regards,
Mark

Bill, Thanks, that is quite reassuring. The "sludge" is very sticky - I only noticed it when I went to lift the gauge rod up and I could feel it sticking to the bottom of the tank. What I found on the end was some dark brown very sticky residue. I have never had a problem with dirty or watery fuel, so I do believe that what I am seeing is not an urgency. It doesn't strike me as a DIY job though, so as you suggest, next time we're in a reasonably up to date location, we'll call an expert. Cheers, Paul Ya Fohi - Amel 54 #98

When you undertake this project, the best advice I can give you is to label EVERYTHING. When it comes time to put the membranes in and put it all back together, it can get very confusing very quickly.
