There are a few issues with the amateur radio equipment aboard the
ISS. The only working ham rig at the moment is the 5 watt Ericsson HT.
So the downlink is weaker than what we historically recall. The FM
deviation seems a bit more narrow as well.

This report from the ARISS International meeting may offer additional


I hope the mailing list doesn't mangle the long URL. Anyway, when you
get halfway through this article there is a link called 'presentation'
which gets you the PowerPoint slides from the meeting. The ARISS radio
gear is discussed in the slides.

I've also found that orientation of the ISS with respect to my QTH
affects how well I am heard on the uplink and how well I hear the
downlink. Perhaps that is another reason the APRS gates aren't

When you see my greetings on 145.825 I am always at the keyboard ...
no beacons here. We can try for a packet QSO.
