The modified ft8_lib available at , and it offers a better handling of nonstandard callsigns . However, I wasn't able to simply use it as a replacement of the original ft8_lib sources in the or firmwares.
It looks like certain non-trivial integration work is needed. Unfortunately, I won't be able to take a look at that before the half of July. Has somebody else succeeded to replace the original ft8_lib in [s/z]Bitx with that improved version?
?
