Re: LF: LF EbNaut TX Announcement

Although it will be some years before I can have the necessary
equipment to run EbNaut I am *very* interested in QSO modes, so I
want to comment on this.

Please use more than 12 character messages. Rememberfor QSOs you
need room for two call signs plus some kind of signal report or
other piece of information. That means at least 13 characters. Also
some may need to use compound callsigns which are longer than 6
characters. I think 15 should be a minimum, but this still leaves no
room for some compound call signs. More than 15 would be better if
it can be done without giving up too much. Look at some of the
problems they have had with WSJT because of the very short message
length and special compression used.

I must agree that EbNaut can only become popular as a QSO mode after
all the protocols have been worked out *and* someone writes user
friendly software *and* more "beginner level" help is written. As it
stands now, I think only a few "professors" are able to understand
it. Some of us are completely lost.

73,
