RX/RTX Character Set


 

Greetings,
?
I like to decode the Europe feed of news items as described at RTTY.com. Please see the attached picture.
?
The gentleman that is one of the go-to people on this replied to by question as to why apostrophe's are printed as <BEL>.? This only happens on the Europe feed and not on the ITTY feed (US news items).
?
Here is his response:
==============================================
I suspect there is more than just this problem. I think + will print as “ and = will print as ;?
?
There may be a few others. This is because there are multiple standards for Baudot. The US uses USTTY and Europe uses ITA2.?
?
Everything on the Europe feed prints well on a European teletype machine because those printers are mechanically set up for ITA2. When I first put the Europe feed up, users in Europe complained that things were not printing correctly.?
?
One complaint was that apostrophe was triggering the bell on their machines! This is what you are seeing in FLDigi. ?I originally had the Europe channel on USTTY and had to change it to ITA2
Interestingly, the apostrophe and bell are actually switched between the two code standards, so if I send a BEL, European machines will ring the bell but FLDigi will print an apostrophe! If I send an apostrophe, European machines will print an apostrophe but US machines will ring the bell.
==============================================
?
So my question is:? Is there an equivalent character set to ITA2 in FLDigi. There is not one called ITA2.
?
Thanks for reading.

The ITA2 character set is not a part of fldigi, but easily added (or substituted).? You would have to modify the source code file rtty.cxx and recompile fldigi.

Thank you David for your reply. Is this something that could be added in a future version of FLDigi?
