To extend our message networks internationally the Global Simulated Emergency Test (GlobalSET) is the annual practice session for formal message handling. However this is a skill that used to be exercised on a daily basis through the international packet radio network. Efforts are now being made to try and extend the ARRL NTS system to handle amateur to amateur messages outside North America with DB0NTS acting as a message forwarding station to the USA. The predictions here are pessimistic forecasts for a route from the UK to DB0NTS and then for DB0NTS to his USA destination.
