The only three letters in the English alphabet that sound unique when
said are "L", "O" and "R". All the others can be easily confused with
another letter.
Looking at it from a strictly phonetic viewpoint, stay away from the
"eee", long a or long i sounds, which spectrally are much weaker than
"eh", "ah", "oh", and "ooh", in that order.

Subject: [CQ-Contest] Best callsign letters
Has anyone done a study (or have ancetodal evidence) about which letters
(using standard phonetics) get through best on SSB during pileups or
marginal/weak conditions? For example, I though "j" would be decent
letter but many people seem to hear "Juliet" as "India". Don't know why
they make that confusion, but they do. So, which letters are best
recognized and less confused?
