mister p, can you explain your 5k saving figure?

Assuming you already have good cables/aerials in place then a fixed VHF will cost you less than 150 for a respectable unit from a well known brand. (If budget is priority you can buy for just under 100, from less well recognised brands - these may be less suited to the weather onslaught on a rib though). You can spend much more, but there is not really a need to for most users. If the aerials need replacing - the cost will be the same regardless of 25W proper fixed or 5/6W handheld on a fixed aerial.

You can get perfectly reasonably handheld for less than 100, but it won't be all singing all dancing. If you want floating etc - you will pay more. At the very bottom end antennae may not be removable.

Since you are "all legal" I assume you are familiar with the benefits of DSC radio, including touch of a button distress calling - which means anyone can be taught to make a distress call in 5 seconds! Assuming there is already some sort of GPS on board almost any new radio will wire right in very simply and give you DSC benefits. DSC in a handheld will cost you something more like 3x the price of a standard handheld. Beware some really good priced units may not include a 12V charger/craddle to enable you to "wire it in" to the boat, so you will have to pay extra for these.

DSC actually had some other benefits which are skirted over because the red button advantage is so compelling on its own - but group calls, calling the CG without clogging Ch16, being able to position poll a (willing) friend etc - are all useful features; as is the "audible alert" when someone else want to talk to you.

As an extra bit of info , I used to fly several aircraft where I used one ICOM HH on a set up with the external aerial & 12v supply. The aerial was just a coax to replace the stubby HH aerial & the 12v supply via a specific ICOM base that the radio clipped into.

No reason why a boat should be differant ( apart form the harsher environment) ?

The type of aerial connector you need at the radio varies with brand. Some take an SMA, others have a proprietary connector, but will supply a "radio to ships aerial connector". This usually gives you a BNC male to which you attach the 'big' aerial.

Don't try to transmit with the aerial disconnected, it can damage the radio.

Polwart, the 5K figure came from a supplier asked to quote for 4 fixed units........supply and fit with rewire and antennae, this included travel to boats and also the price of a handheld.

For me the figure is a bit tongue in cheek and as yet I haven't got the itemised bill as I have no intention in dealing with these people........someone somewhere must have been expecting another Christmas a few hundred days early!

But it got me thinking and I have yet to make my mind up.

DSC has indeed many underlying advantages. I am also one to always want to double-up on safety equipment, so my thinking was that if I was have two handhelds anyway........is there a way to make one punch above it's weight.

But the more I think about it, the more I am inclined to believe that a fixed plus at least one HH is the way forward. Even if the original idea might throw up some Heath Robinson inventive corner-cutting.

The right gear is already out there (from the right supplier).
So I reckon on four M411 and a couple of M71's. I want to stay with ICOM.

There, decision made. Earlier than I had predicted!

Who told you this as it sounds like bollocks to me.
A radar is transmitting all the time it is turned on, even IF a VHF did cause a health hazard it would only do this when it is transmitting.

the new icom range will be announced at London boat show....I believe a DSC handheld radio

A bit of googling will find the specs, since icom France have published it in their website!

My fixed antenna is on the console. Is this slowly frying my brain?

yes - and that mobile phone you use, x-rays and microwaves are not helping much either....

not forgetting the Wi-Fi and Cordless phone waves....

hence I wear a tin foil hat!
