About ARISS:
?
Amateur Radio on the International Space Station (ARISS) is a cooperative
venture of international amateur radio societies and the space agencies that
support the International Space Station (ISS).? In the United States,
sponsors are the Radio Amateur Satellite Corporation (AMSAT), the American
Radio Relay League (ARRL), the ISS National Lab and National Aeronautics and
Space Administration (NASA). The primary goal of ARISS is to promote
exploration of science, technology, engineering, and mathematics (STEAM)
topics by organizing scheduled contacts via amateur radio between crew
members aboard the ISS and students in classrooms or public forms. Before
and during these radio contacts, students, educators, parents, and
communities learn about space, space technologies, and amateur radio. For
more information, see www.ariss.org.

There is an android program called Orbitrack which can help you identify
satellites that you observe naked-eye or in your telescope.
There are a great many of them, and always more, in all sorts of orbits.

I just renewed membership and request information about compatibility on my
radio ( IC-2730A ) for working the FM birds.
I was hoping to use my IC-2730A along with HRD but cannot find a CAT cable
for compatibility. HRD lists the 2730 as an available radio but no joy
connecting.
I am hoping to connect with someone that IS or HAS used this radio with or
without HRD for help.
If this is NOT a viable radio, please notify me!

Hello Jerry,
The CAT control protocol is specific to Yaesu radios, with the physical
interface being a 9-pin RS-232 port. My FT-847, for instance, has a CAT
serial port on the back of it.
Icom uses CI-V, which is a multi-drop serial port, somewhat like RS-423
except that the voltage levels are +5V and 0V.
(http://www.plicht.de/ekki/civ/civ-p1.html) On my IC-746PRO, this
manifests as a 3.5mm headphone jack.
It appears that you'd need the optional OPC-478UC unit to use CI-V
control of this rig.
I don't know anything about HRD, assuming you mean Ham Radio Deluxe.

Probably on of the Starlink sats, as there is a lot of them that can be seen
very
easily. More to come eventually as there is going to be 4000 of them in a
few years.

Aren't Starlink fairly low LEO birds? How about Iridium? They are a bit
higher, I think, and have some particular times when they are very visible
depending on the angle. Interesting discussion.

The Iridium sats with the highly-reflective surfaces have been deorbited,
except for a few that can not be deorbited due to failure. They still
flare, but since they don't preserve their attitude any longer, it is no
longer possible to predict a flare.

Content-Type: text/plain; charset="utf-8"
A little food for thought:
Any idea what the chances would be of having something like 1 night a week
or month, on ONE of the FM birds, that could be reserved for HT access only?
My thinking on this would be a great way for people to test out their
portable or limited satellite stations with a great deal less collisions
against all the other much stronger stations.
I have heard from plenty of people that would like to try a temporary or
portable station on the birds, but we all know that?s not even a remote
possibility unless your on super early in the morning or late at night.
Ie.. it would be great to see how many people could test and build their
skills to operate with an HT and an arrow or something, kinda like the old
days. ?
Just dreaming out-loud. ?

Hi-RS44 varies in altitude from about 1180 to about 1525. Seemingly always
