I use Cqrlog & JTDX (or sometimes WSJTX). I prefer JTDX because decodes much more contacts.
I installed GridTracker but I can not manage to get them working. Ports seem to be properly configured (127.0.0.1:2237, same on JTDX and GridTracker but nothing happens on GridTracker).
I use ufw as firewall and I also tried with the fireall disabled, with no result.
Any help, please?
