I have just uploaded a new version of 2Tone. It can be found here:

And no doubt Don (thank you) will upload it in due course to:
http://www.rttycontesting.com/downloads/2tone/
This new version fixes a few minor items but the big one is it will now look
for character strings that are repeated and combine the analogue data
together to provide an output that has a lower probability of error. To
distinguish this synthetic output from what was actually decoded its output
is surrounded by curly {} brackets, e.g. { G3YYD }. Occasionally, it will
get the matching wrong and give a false output. It is possible to turn this
off see the documentation that comes with the upgrade.
In the recent WAE RTTY contest two stations in the UK found that in 4% of
their QSOs that this new system saved asking for a repeat. The normal repeat
request rate is 8% of QSOs. A 50% reduction is very worthwhile.
It does however require that the sent information is correctly formatted,
which it is in most cases. The format required is for the repeated
characters to be at least 6 RTTY characters long and surrounded by space
characters. Examples of this are, the quotes are for clarity: " G3YYD G3YYD
" or " DAVID DAVID " or " IO92NQ IO92NQ ". However " ED ED " will not work
too short or " DAVID DAVID, " will not work comma after 2nd DAVID. " M7T M7T
" will work as the figure shift, letter shift and a space character make it
6 RTTY characters.
It is not just for contest, it also works for everyday QSOs. Just make sure
when sending you name, QTH etc to apply the rules as above when setting up
the macros.
