…even if you sending radio is already turned off.
This is possible thanks to the Brand New APRS Gateway for QTC Net that is
running in Test operation for 500 km round of vienna.
As soon as a call sends some beacon message whatever, pending messages in
QTC Net the Gate tries to deliver them via APRS.
If you wand to use the other way round you have to set a QTC Net Alias.
You may set up your own QTC Net Node and Gateway in your own local area.
