Yes Steve, you are right and thanks for this remember.

But my question was : how to verify a tactical call sign ?
Can give me exemples for stations with tactical call sign.?

For Sergey, if you want to stop no hams call, put in UI-View in the exclude liste, the call what you want not hear and the history is finish.

I cannot over-emphasize this...

You cannot verify ANYTHING that appears on the APRS Internet System.

Anyone can send anything. Anyone can send something that appears to originate from your callsign. Looking it up on QRZ is meaningless, because even though your callsign is there, there is nothing that keeps someone else (ham or non-ham) from sending something with your callsign. Yes, you can show that F4ARO is a real callsign, but it cannot be proven that you actually sent it.

I've gone through the history many time before, the short version is that the very weak authentication that was in place to meet the requirements of the US Amateur Radio rules was invalidated when an open source software author felt the only way to satisfy the requirements of the GPL was to release the program with the source code for the validation algorithm, nearly a decade ago. Nothing can fix it short of a complete redo of the APRS IS. In the meantime, all we can do is take solace in the fact that there have been few problems over this decade.

From when I first conceived of it I wanted it to serve as an ambassador for amateur radio, one that showed a new audience of people the value of amateur radio. It has succeeded in this regard, I have heard from many people who became hams after being introduced to the possibilities through the internet side of APRS. A large number of the users of the APRS IS are not hams (yet) and that is not a bad thing.
