Success! Packet Radio via the International Space Station

I think this was my third or fourth attempt, but I just successfully bounced a packet off of the ISS as it passed over this evening – if I understand this right, the red highlighted message is my message as I received it coming back from RS0SS (the callsign for the packet digipeater on the ISS):

Amateur Radio Packet via the International Space Station (update 2)

On yesterday’s pass I realized too late that the AGWTerminal software doesn’t send unproto packets needed to send packets via the ISS. I’ve now downloaded UISS, got it sent up and checked into the Sacramento Valley Sunday evening packet net, so looks like everything is good to go.

On this evening’s pass, I started sending my cq unproto packets, but looks like I wasn’t heard. I’m wondering after reading around that my ‘via’ value should be ARISS and not RS0ISS that I was using. Apparently your via should be ARISS, but the packets recevied from the digipeater on the ISS will come from RS0ISS. So, will give it another try on the next pass at a good time.

Here’s the packets I received this evening:

Fm K7LWV-6 To APRS Via RS0ISS* <UI pid=F0 Len=47 >[21:08:50]

Amateur Radio Packet via the International Space Station (ISS)

I’ve been meaning to try out packet radio via the ISS packet digipeater for a while. My first attempt the pass was less that 50degrees and I didn’t hear anything during the pass. Tonight there was a 76degree elevation pass – for this try I had my Icom 880 set to 145.825MHz, connected via a Rigblaster to a laptop running AGW Packet Engine. My antenna is just a homegrown 1/4wave vertical in my attic.

All set and ready to go, I started to hear some activity just before the peak elevation. I tried sending my unproto packet, but found out the hard way that AGWTerminal only does connected mode, and won’t send unproto packets. Found a discussion here as well, so I guess this is a limitation of AGWTerminal.

Apparently UISS is the app of choice for working packet via the ISS, but there wasn’t enough time to download it and get it installed in time for this pass.

I did receive some packets though, so although I didn’t get a chance to transmit, here’s what I received on this pass:

1:Fm K6PKL To CQ Via RS0ISS* <UI pid=F0 Len=42 >[21:58:00]
