I really like using VOX ATC, it's one opf those products with depth and complexity which takes time to get down into, but is really rewarding!Question: I'm using VOXATC in a 747 cockpit, with FS2CRew and an admittedly compley setup over several PC's, but I cannot get ATC to append the "heavy" callsign to a 747. In real life, there are many aircraft that use this designation, so I am obviously missing something in the setup.When I manually change the ATC callsign in VOXATC setup, I am prohibited from appending letters, prompted that "...callsigns are letters followed by numbers..." any ideas, please?Kind regards,Trev Meacham

Did you try setting "Airline" in the setup window instead of leaving it "GA" or "USGA"... it's in the help menu;).

Sorry about the delay, some long flights... :-)No difference changing GA/USGA/Airline. In Airline, I still get the message "airline callsigns must be letters followed by numbers..". I even looked in the aircrafttypename XML file, where the abbreviatiation "hv" is changed to "heavy", so I tried adding hv. No joy. I tried all combinations, having to restart FSX each time (hence the delay). qantas427 correctly reads as "Quantas four two seven" but nothing else is accepted after the numbers.Incidentally... when in European airspace, Qantas is correctly pronounced "kwantas", but in Australia (Where Qantas comes from!) it's pronounced "Kantas". Any idea on this one?Also, ATCAircraft Type Name Editor crashes with the dreaded MS Message "ATCAircraftTypeNameEditor.exe has encountered a problem and needs to close. We are sorry for the inconvenience."I'm not trying to be painful, I really like this product!Any help would be appreciatedTrevor
