But in APRS1.2 we have defined what we call ITEM-IN-MESSAGE
format.  It DOES let you send an object within a message to a
particular station.  This feature is exactly for the purpose you
desire.  The AVRS system will respond with such an object so
that the messaged-station gets the FREQ-object info on his

You can SEND it now.  The Igate WILL send it out to RF.  But
until APRS clients and radios begin recognizing it, it more or
