That is good to know!
In the radio there are two settings; Network and Packet Path.
Does the "Network" stay "APRS"? Or should it be set to "ARISS"? I assume the Packet Path becomes "ARISS" or "APRSAT". Correct?
Thank you!
Best regards, Fred N7FMH

Actually, when you use ARISS or APRSAT then the signal comes down as RS0ISS* if it went via ISS, and comes down as PSAT,ARISS* or PSAT2,ARISS* if it went via one of those. Yes, it is a parsing pain, but a simple rule. If you see ARISS*, then simply find the actual satellite in the previous field.

Just a thought -- one of the benefits of using the actual call sign (RS0ISS, PSAT, PSAT2) rather than ARISS or APRSAT is for the record.
For example, I am calculating the Az/El of each contact based on the digipeated (PSAT*) path. When the digipeated path is ARISS or APRSAT there is no good way to clarify which satellite participated in the packet.

See the Az/El columns for PSAT; I plan to add Az/El for others sometime soon.
As a consumer of the data, I prefer seeing the individual call sign. As
the
user of the radio, I can see how using APRSAT for everything is more convenient.

Yes, that's correct. FalconSat-3 doesn't digipeat using the generic

or APRSAT paths.
Agreed, it's a pain to have to keep changing PATH, baud rate, and data band between FalconSat-3 and the other packet satellites. At least there are only two configurations to have to toggle between. Once you've done
it
a couple dozen times, it becomes second nature.
Yes, PSAT2 (and apparently also AISAT) may need to use Narrow FM mode,
but
the mode can be easily programmed into memory channels. I just set up a different set of memory channels for PSAT2 and AISAT to set that mode
and
enable (crude) Doppler correction. I haven't used them yet so don't know
if
5 kHz steps will cut it.

Regardless of the other operational requirements of FalconSAT-3, you
are
saying FalconSAT-3 will not digipeat using the generic paths. That means the text in the links provided is incorrect. Or is there some other qualifier I have missed?
PSAT2 is also a different beast apparently. The text in the link imply APRS uplinks are narrowband. From the PSAT2 link:
Uplinks: 145.825 MHz narroband [sic] FM packet and 29.4815 MHz SSB PSK31 User Station Software Configuration: First bullet - Radios must be in Narrowband and track to 1 KHz Doppler
on
the uplink.
The reason for asking is to be able to make as few changes to an HT
(D72)
as possible. And the main use is to achieve a digipeat. When a satellite
is
the only APRS network available it could be a useful way to get
information
out.

FalconSat-3 is a different beast: 9600 bps vs. 1200 bps, and crossband
at
different frequencies than the 1200 bps packet satellites. If you want
to
be digipeated by FalconSat-3, you need to use the PFS3-1 PATH.
