Most people can surely work out that fixed is 25W. What concerned me is that you thought handhelds worked at 1-2W? Yes, as you say, handhelds work at 1W at times, but either you have to select a channel where that kicks in automatically, or select it yourself. The rest of the time it's typically 5W.

Anyway, I'm with you on having a fixed set with hand held for backup, but a hand held is far better than none at all. The next issue is taking the exam, and understanding these issues?

Yeah, I know the handheld has a much lower range but I was picking up on Scary Des's thoughts - if the worst should happen and we end up in the water instead of in the boat, just how much range would we have then? Would we still get about 5 miles or would this be reduced, what with the radio being held next to a face which is bobbing around on the surface of the sea, rather than 1.5 - 2 metres above sea level? Anyone know for sure what the answer is?

Realistically, in those conditions, range is going to be dependent on the quality of the radio you have, and sea conditions, and will be 2 to 4 miles max. My handheld has an attached speaker mike, which means I can hold the radio up at arms length, and use the speaker mike to talk and listen, but even that won't make a huge difference.

That's about what we thought. We figured having the radio would be better than not! So Richard'll carry on wearing it round his neck as back up to the fixed set. Cheers.

I don’t really get that, if VHF is ‘line of sight’ radio, how can it work beyond what you can see, remember I am talking about rough conditions with 1mtr waves and you are in the water. Des

as I said to Louise. 2 - 4 mile MAX! and it depends on sea conditions! If you are in rough conditions, you'd be well advised to make the most of the time you are on top of the waves, not down in the trough

A couple of other things worth pointing out. From practical experience, handhelds transmit better than they receive - so even if you are not getting a response, your transmission may be getting through. Coastguard radio aerials are usually up high and are very sensitive, so line of sight is not water level, but up to the top of cliffs etc. and sensitive enough to pick up weak transmissions. You might not get good line of sight to another boat in the area, but coastguard may still be able to pick you up if you are near one of their aerials. A lot of factors that can make things work, or not. Personally, I have a set of mini flares inside my life jacket to complement the handheld should I go overboard.

So in the case of over board along the coast a Mobile phone may be better than a hand held VHF?
It dose not knead line of sight!

We each carry one of those, too - around our necks in Aquapacs.

Mobile phones need line of sight as much as VHF radios, though it's not always obvious - no reception at all on mine while out walking on Sunday in a valley in Wilts, even though only 2 miles away from the mast

There are also huge areas where there is no mobile reception along the coast(St Albans head area springs to mind on the south coast). Still handy as a backup, but I wouldn't depend on it.

seems like footstarps are the best way of ensuring good coms
