[RTTY] 2Tone Te4sters required

[David G3YYD]

I am in the final stages of testing an update to 2Tone and it should be bug
free but you never fully know. So if there are a few who would like to try
it out and let me know of any difficulties or none that would be very
helpful.
 
Just email me direct but you must do so with an email account that allows
zipped 2Tone.exe files as an attachment.
 
For those who would like to know what I have been up to here is the change
notes: 
 
17.10a Improved repeated character string function, lower correlation
threshold with lower error rate and changed ITA2 to ITA5 code conversion
table. Character sync on receiving new transmission improved and starts on a
new line. Character sync during received transmission improved so character
sync is only lost when data bits are in error. ATC function upgraded. Fixed
reverse shift (receive only) from logging program error. Added new setup
choice: contest mode that maps some corrupted characters to the correct one,
not fully compatible with rag chewing QSOs. Changed to using VS2017 with
2017_XP compiler.
