locked #Important : JTDX users MUST use the JTAlert JTDX shortcut #Important

HamApps Support (VK3AMA)

In recent weeks there have been a number of users repeatedly spotting FT4 spots to HamSpots as Q65.

This is caused by the user using the JTAlert WSJT-X shortcut when running JTDX.

The problem stems from changes the JTDX people made to the WSJT-X UDP protocol. Specifically, the UDP decode message contains a single character that identifies the mode for the decode. The WSJT-X standard uses ":" to identify Q65, but JTDX chose to use ":" to identity FT4 decodes.

JTAlert overcomes this by using an alternate character to mode mapping table for JTDX users.

To change the character to mode mapping JTAlert needs to know what application you have JTAlert working against, WSJT-X or JTDX, this is why there are different shortcuts to start JTAlert, the Red "X" icon for WSJT-X and the Blue "X" icon for JTDX. This has been in place for quite some time.

Recently a number of users have been using the WSJT-X shortcut when running JTDX, as a result, if they are working FT4 all spots to HamSpots are flagged as Q65.

The fix is simple, use the correct JTAlert shortcut.
