Brendan's test would be a more acurate way of getting the answer you need.

We have access to lots of computer simulators and programms for working out path loss but the only real way to get a right answer is a practical test.

When I have set up radio system I always do a live test, as I said only way you will get the right answer.

On different days you will get different results too.
As I said so many things can and will effect VHF comms.

Is that a yes? Range 5.3mtrs Des

Its a - I would need to test before answering that as I would not want you to think it is ir is not without.

That vague enough for you?

Sorry but I would want to test the theory before giving a deff answer.

Jon for politic? no I don't think so!!!

Brendan's test is a good idea of what you can expect.

It was a short sharp nasty 1 foot chop, though as is ever the way with these things, some were larger some were smaller.

- after 20 minutes in the water, they start looking a lot bigger!

Brendan’s test was conducted in 1' swell (unless he made a typo), in my book that is smooth, I am taking about rough weather, the type of weather that makes you fall out of boats. Still I agree we should test it I think the results will be very interesting.

Just to add to the range debate,


In a high pressure weather system the range of Vhf is dramatically increased. We can listen to Liverpool and Dover coastguard sometimes.

I‘ve got to take the boat out later, should be a bit lumpy. I’ll have to see if the wife is up for a bit of testing, She’ll probably think it is an elaborate ruse to get her life insurance money. Des

Given the relative heights of your aerials I guess that is almost (+1/3) line of sight. Or is it stratosphere bounce ? Des
