A message from space. Well not strictly FROM space

I came back from a nice walk through the countryside, having picked a lovely amount of blackberries, damsons and sloes and popped into the shack. Earlier today, I’d started up my APRSIS client (APRSIS32 by Lynn, KJ4ERJ) and left it running.

I noticed there was a message waiting from Julian, G4ILO-6. I opened it up and to my surprise, it said ‘Hi via ISS’. Julian had launched a packet on 2m, it had been digipeated by the International Space Station and then come back to earth where it had been received by other iGates on the APRS network and found its way to me.

Thanks Julian for a really interesting message!

If you want to read about how this works and see the stations that have been heard by the International Space Station have a look here.
