RS0ISS packet radio system would be awesome if one could upload with a 5 W handheld radio and Arrow antenna. I have tried numerous times to upload APRS data, even when I could see ISS in the sky, but my 5 watts are not enough.

On the other hand, QRP voice operations with ISS are possible. I have had the pleasure to talk to cosmonaut Valery Korzun with a TH-D7 (5 watts). It would be so cool if everybody transmitted QRP to ISS!

Yes Mario, it would be really nice.

Unfortunately plain AX.25 does not handle packet collisions and that is the main reason of failures.

Such a simple system allows a very large number of potential users to be part of the game, but introduces many troubles... Like the one I said before.

Mario - try using a Cush Craft Dual Beam 5 Elements each band. Much more gain. I use the HT and the beam for connecting to UO-14 & AO-27. Arthur N1ORC

Make certain your settings are correct. ISS should hear you easily on 5 watts. .. make certain your UNP is set correctly.

Thank you to all. Last weekend, on Canadian Thanksgiving, I went to my hometown in Eastern Québec, near Trois-Pistoles. Quite unexpectedly, I succeeded in contacting ISS!! Was it due to a better UNP, or because I was using the same frequency for RX and TX (145.825), or because of that new RS0ISS-1 address?

The experience was again very exciting. I was having dinner with our family and friends. We all went outside to admire the view of ISS passing in the night sky just above our heads. At that same moment, I succeeded many times in receiving and sending data. I just could not believe it! :o)

I agree with Mario(va2va) if more people would try qrp maybe us little guys limited to 5 watts could make it through instead of haveing to take a back seat in the pile ups.

Just my thoughts.

What gives with ISS packet?? I have been trying all week after setting up the packet system. I have a couple of replies last week when I was testing the system, but nothing now. I look at the web site for reporting ISS packet and I see the last contact was 6 days ago. Someone must of bumped a wire, or forgot to turn it back on.
