It's been back on for a couple of weeks now. You can view a live view of the
ISS activity from a page on my website at:
. <http://wa8lmf.dyndns.org:14439/mapISS.htm>
This displays KJ4ERJ's ISS object from the APRS Internet feed on a world map.
When the ISS is within range of my home station in central Michigan, the map
switches to a more detailed view of eastern North America, and displays what I
am hearing off the air in Haslett, MI.
The receive setup is an Icom discone antenna and a BearCat 760 scanner. The
scanner's "Tape Recording" output is fed into a Behringer UCO202 external USB
sound card plugged into a cheap netbook PC running the UZ7HO sound modem and
the UIview webserver. Heard stations are also gated to the APRS-IS
The expire time for received stations is 80 minutes, so received stations
disappear just before the next pass. I.e. the displayed stations are always
the current or most recent pass.

At least 3/4 of the beacons my setup receives are fixed stations are the same
on every pass.
They appear to be beaconing 24/7 just like typical home stations on 144.39.
(Once in a while, when two-meter extended propagation is happening, I see some
even when the station is on the other side of the world......)

I'm currently on the road (sending this from a McDonald's in Ely, Nevada)
returning to MI from the west coast. Tomorrow will be my combined 30M APRS &
30/40/20/?? meters SSTV portable operation from the top of Mt Evans, Colorado.
