Hi All,

The key issue is that the 5CT call sign does not fit with the source coding of 
call signs. The third character needs to be a number. The 'third' is seen as 
second in call signs commencing with K, G etc. as then the first one marked to 
be empty. See Protocol specifications at 17.1. of User Guide.

So on the source coding point of view there is no call sign and the message is 
encoded as free text (with the 13 character limit).

1>I suspect its due more to the fact that he was using the Tx5 message with its 
13 character limit, and not the Tx6 which allows the addition of up to 4 
characters between the 'CQ' and the callsign, and will also include the full 4 
character grid in the transmission.
