Hang on. Are you now talking about the Message _addressee_ field, or the 
AX25 'Destination Address'?

The 'TOCALL' I read as the AX25 destination address, which in my case is 
always "APSAR".

Please use the correct identifiers for the APRS spec.

SARTrack currently also locks the Message addressee field to uppercase.
I can easely remove this.

Please advise if you want that.
