    We've noticed a huge increase in rants and negative posts that revolve around agencies going to encryption due to the broadcasting of scanner audio on the internet. It's now worn out and continues to be the same recycled rants. These rants hijack the threads and derail the conversation. They no longer have a place anywhere on this forum other than in the designated threads in the Rants forum in the Tavern.

    If you violate these guidelines your post will be deleted without notice and an infraction will be issued. We are not against discussion of this issue. You just need to do it in the right place. For example:

Hello, yesterday I had the joy to see and hear the ISS. I picked up activity in 145.80 Mhz, it was packages, and I was really excited because I was in a roof, simply with the stock rubber dock antenna of my Pro-95! :D Just wondering if someone knows what kind of information is sent. Curiosity.

Thanks

Luis, basically the Kenwood radio the Station has is sending out packets that say that the mailbox is up and is looking for folks to connect to it. Hams can connect to the mailbox - which stores messages - and at times, leave short message for the astronauts. It's something of a challenge to connect to the station and once done, you can get a QSL for it.

It's unlikely the astronauts will respond to the messages, however, it's been known to happen that on another pass, if they recognize a ham's callsign from one they saw in the mailbox, that they'll mention it during the voice contact with the ham.
