That can backfire and waste time, due to people not understanding the letters. For example, my callsign under adverse conditions could be mis heard as (heard most of the following on terrestrial repeaters or IRLP/Echolink, let alone on the birds!):
VK3JEB VK3JD VK3JB VK3JEV VK3JV
And the list goes on.... ;) The overhead in asking for clarification or getting a correction outweighs the overhead of using phonetics in most cases. Once callsigns are confirmed, you can drop the phonetics (though usually by then, the QSO is over, so someone else can have a go ;) ). Phonetics are also more likely to survive brief bursts of QRM or brief fades.

I asked as I am still puzzled why in the US on local FM nets hams just use "n,3,r,d,x" instead of "november three romeo david x-ray".

Probably because David is not a member of the approved NATO alphabet.

I do that on FM repeaters and on the birds when I'm working with people who recognize my call sign or are likely to. I'll switch to phonetics if there is someone new to me or when I'm calling CQ

Samudra, I think that typically on FM repeaters, you should be able to understand the letters being spoken as easily as phonetics since there is usually so little noise on a local FM repeater as compared to a satellite signal where you are dealing with fading and QRM much of the time. BTW, thanks again for all your help during the Symposium.
Dave, AA4KN
