Hello Arnaud,

I could give you the address but you won't see anything since there are no 
alerts at this time, also the application is running only when there are 
active alerts and then refuses inbound connections. But you can see for 
example the packets below:

ATTHWS>APRS::NWS-ADVIS:201900z,WIND,GRC423{K0kAA
ATTHWS>APRS::NWS-ADVIS:211100z,WIND,GRC423{KASAA

I could do that, but I was wondering if I could somehow avoid the extra 
"cancel" packet.
