Hi, I see all kinds of photos and try to figure out the best spot to place the VHF radio. Can you share your experinces and give me advice for a good spot. Most important to consider is my solo trip to Norwich, so thinking about external speakers? Looking forward to your replies.
Regards Alex/ Nijkerk/The Netherlands.

Do not fix it under a window where condensaition can leak on to it.
Have it near enough to the companion way to allow use in the cockpit in an emergency keeping your eye on the victim / problem.

My fixed VHF is tucked into one of the side cubby-holes. I've found it pretty much useless for single-handing - if the outboard is running then I can't hear it in the cockpit and I have to leave the helm to use it. I tend to use my hand-held. I'd consider saving my money and just having the hand-held.

If you single hand then the only way is to have the radio accessible easily from the cockpit. I would not have my installation any other way than on Klipspringer, see the link below. This installation swings round so that you can use it down below if required. Contacting lockkeepers while still able to manage the boat is fantastic.

On my last boat the radio was mounted on the main bulkhead and although I could reach in and grab the microphone I could not see the radio display without going down below.
Another point about radios if you haven't already bought one. I recommend getting a microphone which has a built in keypad. this makes channel selection and changing so easy. I have the Mtech MT500 which has this feature and is in the photo above.

I have a DSC VHF in the boat and a handheld standard horizon HX300. I find that I use the handheld most of the time as it is so accessible when entering or leaving the marina and seems to have a good range. Battery life is excellent but I made a 12v cig lighter cable to charge on the boat. Battery is LiPo so doesn't self discharge at all.

On a separate note have people found the Low Self Discharge NiMh batteries. Charge as per normal AA but keep their charge, lose about 5% a year unlike normal NiMh batteries which self discharge?

Hi Norman,
Thanks for your photo, I will probably do the same, but I have some questions as you seem to have a big panel of electric devices, did you connect them all to your engine battery ? How long does the battery last if you have everything switched on ? thanks Alex

Hi guys,
thanks for your advice and photos, probably I will copy Norman's set up.
I will post the photos when ready.
Thanks for now,
Regards Alex

If you are going down my route then read my comments in my refit discussion

2 points to add
1 you need to make sure the box is well supported and braced otherwise it will vibrate
2 I sited the box in such a way that I could replace the ply wooden washboards with a transparent one for use in the wet so that I could batten down but still see all the instruments.
To answer your questions:
Yes all connected to the boat battery. I have a bank of two leisure batteries wired so that they are interchangeable. I do not need a battery for engine start (outboard in well). The batteries are charged with a flexible solar panel on the garage roof and also from the engine when working. I very rarely have everything switched on. Last time I can remember was going into Cardiff at night with nav lights and all instrumentation on but then I had the engine on. I normally sail with handheld chartplotter ON connected to boat battery and connected to radio for DSC. Radio is ON. NASA wind is ON and NASA depth. The tiller pilot is often on, but not always. I tend to use the main chartplotter to supplement the handheld when in more difficult areas, either navigationally or busy when my AIS engine will pick up the large ships in my area and display them. The same goes for the fishfinder which is also useful when anchoring to get an idea of what is on the bottom. I also have a Naxtex receiver down below which I leave on if I require another view on the weather forecast.
How long any battery lasts will depend on many factures Size of battery (I have 2 X 80aH). Type of battery which will determine how low you can discharge without damage to the cells. State of batteries. Current drain of each instrument. If you look at the spec for each of your devices, this will give you a current drain in amps. Multiply this by the length of time you need you need that current for and this will give you your amp-hour requirements. Multiply this by 2 at least for the size of batterie(s) if standard leisure.
Incidently I forgot to mention that I also have a fridge on board. This can be powered off the mains when in a marina and off the battery when not. I v rarely use this on battery power for obvious reasons. If you want to talk to be about any details then send me an email with your phone number to norman@achillesyachts.co.uk. Don't put such information on this site since it is public.
Good luck
Norman
