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.

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".
