As far as I know on RTTY there is no difference in the transmission length
between different letters and numbers but a longer callsign of course takes
a little longer to send. I have done many RTTY contests using a club 1 x 3
callsign instead of my 2 x 1 call. The 1 x 3 call theoretically takes 0.15
seconds longer to send than my 2 x 1 but I don't see this as a disadvantage.
A better way to shorten RTTY transmissions is to only send necessary
information, just like you would in a SSB contest. Example: don't send
callsigns over and over during the exchange. If you want to really improve
your score, adding a second radio and upgrading your antennas are a great
way.

Re: contest calls with all the USA 1x2 and 2x1 calls used up
2x2 calls seem unpopular, but sometimes they are shorter or better than 1x2
or 2x1 calls. AE5TT is shorter than my call, AB1J, and easier to copy. Folks
like AA5AU use 2x2s quite successfully.
1x3 calls can be relatively short and easy to copy, too, depending on their
characters. Wx3 calls are popular because of their long tradition.
On RTTY, it's just call length, as far as I know. I don't know if some RTTY
characters more difficult to decode than others. Maybe someone else does.
