Hello Rik,

Perhaps the simplest way is to send a text message to a user
specified mobile phone number. At least for most mobile phone
carriers in the U.S. this message can be sent using email protocol.
The message text could simply be the decoded line from SlowJT9. It
would be up to the user to set his preferred notification on the
smart phone.

But how to send the text message (email) from SlowJT9? I don't know.
In linux I think there are command line email tools which could be
passed the message and destination address, but I am not aware of
the equivalent for Windows.

73,
Paul N1BUG
