[600MRG] Audio alert for JT-9 activity?

Hello Neil, Paul, all,


sorry for the delayed reply, but I have been very busy otherwise the past weeks.

But now I have a test version of SlowJT9 (not published yet) that allows UDP broadcasting.

But how to proceed?


The initial question (raised by Chris, 2E0ILY) was to be alerted when certain messages are decoded, even when you are not in the shack.

The best way to do that (in my opinion) would be a smartphone app that "buzzes" and displays the decoded message whenever somthing interesting is decoded, so you can have a look and decide wether you want to rush into the shack.


I have however no experience at all in creating such apps (if possible platform independent, so it will work on Android, Windows and IOS).

As a test I did write a small Java app (class) that just dumps whatever is broadcasted by SlowJT9 and it seems to work fine over a local network (127.0.0.1).


Is there anyone who has experience in this field and is willing to help? Either by pointing me into the right direction or (even better) by creating such an app.


73, Rik  ON7YD - OR7T

UDP would be very useful if it is possible to implement, as then we could use any alerting method with a simple piece of code as I do for WSJT-X

Hello Rik, all...

The alert feature would be useful to me.

Ideal alert level to me would be new station *or* DX station (based
on distance). But if I have to pick on, then new station.

Alert via a pin on a serial port seems best, as long as it has the
possibility to work with some of the better USB to serial
converters. I have three sound cards, it's still not enough, they
are all busy. :)

73,
Paul N1BUG
