[amsat-bb] APRS Satellite PATHs

Here is the APRS satellite Sujmmary:
See http://aprs.org/sats.html

FALCONSAT is not a generic APRS satellite on 145.825 like the others And
was only turned over to APRS digipeating after it finished it original
mission.  It has a different frequency, a different modem (9600 baud) and
is full duplex and is not identified as being a "generic" digipeater with
those aliases. But it is a great new capability for Mobiles (the only 9600
baud APRS satellite).

The APRSAT and ARISS aliases will work with ISS as long as the kenwood
radio is acting as the TNC because it can support multiple aliases. But
sometimes, the backup TNC is used (going back a decade) and in that case,
it only supports the RS0ISS call and not the added APRSAT and ARISS
aliases.

Hope that helps.
Bob

Greetings,

According to http://www.aprs.org/iss-faq.html WHAT PATH DO I USE?
All APRS satellites and the ISS support the generic paths of ARISS or
APRSAT. Since all of these satellites supports the same generic paths
(when properly configured), this means you can operate either ISS or PCsat
or PSAT without reconfiguring your TNC! Just set your UNPROTO path to APRS
VIA ARISS and it should work with all APRS birds.

And: http://aprs.org/psat2.html
Sister APRS Satellites: Other APRS transponder satellites on orbit or in
work all share a common uplink, a generic digipeter alias (APRSAT and
ARISS) and a common downlink (145.825 MHz) so all user traffic appears on
the live APRS satellite downlink page and ISS downlink page. The graphic
below shows how the commonality of all this operaation integrates together
with worldwide users and the internet linked ground stations.

Are these statements really true?
If so, why would I consider using the PATH of PFS3-1 for FalconSAT-3 or
RS0ISS for ISS?

Thank you!

Best regards,
Fred N7FMH
