Re: RX/RTX Character Set


 

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.

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.

George
