I agree with Rich. 3XY has been the "standard" more than any other call I have
logged in at least the past 6 years from there. I stand by what I stated
earlier. The station Bill mentioned is probably "grandfathered" with an older
call.

Subject: Re: [wsjt-devel] FT8 Call sign anomaly with 3XY4D
Hi Joe,
As I mentioned, I understand what the users manual stated about the format of
call signs as I also quoted it. However, in the case of the 3XY prefix, it has
been used for over 18 years. Since 1999 I've made 63 QSOs with stations
operating in Guinea and 46 of them were assigned the 3XY prefix include 3XD2Z,
3XM6JR, 3XY2D, 3XY8A, 3XY6A, 3XY7C, 3XY1L, 3XY1D, 3XY0A, 3XY1T, 3XY3D/p and
today 3XY4D.
I understand the reluctance of making 3XY a special case, but over the years,
the majority of the assigned calls for Guinea have had the prefix 3X plus
another letter, a number and 1 to 3 letters. Since the 1980 start of my
electronic log of 131K+ QSOs, I found a total of only 106 QSOs with such
formatted prefixes. So unless a general exception can be made for calls of that
format I guess the DX station stuck with such a call sign and those of us
calling him will just have to deal with the occasional confusion that will
occur when such a station call sign shows up.
Since a similar prefix, 3DA0 does not result in this problem, I guess the best
fix would get the folks who maintain the CTY.DAT database to add "3XY" to the
existing "3X" valid prefix for Guinea.
Thanks again to you and the WSJT-X development team for a great piece of
communications software. With 75 Watts, an A3S and wire antennas, as of this
writing I've made 7823 FT8 QSOs in 176 countries.
FT8 is GREAT!

The behavior you described is no surprise to anyone who has read the
definition of what's treated as a standard callsign in any of the slow
modes in WSJT-X.
See, for example, the original defining document for JT65:
J. Taylor, K1JT, "The JT65 Communications Protocol" (QEX,
September-October 2005, p 3):
http://physics.princeton.edu/pulsar/K1JT/JT65.pdf
... or the WSJT-X User Guide here:

Relevant text:
"A standard amateur callsign consists of a one- or two-character prefix,
at least one of which must be a letter, followed by a digit and a suffix
of one to three letters."
The callsign 3XY4D does not follow this worldwide standard convention.
For this reason, the messages you showed are all treated as free-text
messages.
I am sure it is very frustrating for 3XY4D, and also for those trying to
work him (as I did, yesterday, by using free text messages in FT8).
In principle, we could make a "3XY" an acceptable, three-character
prefix, as a special case. Not a very attractive possibility, but...
