[amsat-bb] Standard for AMSAT status board observations of FS-3

Fri Jun 1 20:28:41 UTC 2018

I used to know the answer.  But too old to remember.

It might be that, even though the radio is full duplex, the TNC might be
half duplex?  And since the satellite turns around the packet INSTANTLY to
the downlink, that the TNC is not ready to receive packets quick enough?

This can be proved not true if anyone has ever seen their own downlink
packet.

BUT Wait, all it takes is anything else queued up on a busy downlink to
cause the data to be queued up a bit and then you will see your own packet
because every thing is waiting a few milliseconds.

So Seeing or not-seeing your own packets may or may not prove anything about
this theory.

 one "should" see decoded Msgs in the "MSG" list on the D72A, however.
Correct?

  Hi, John.

I don't recall ever receiving that indication that I've received one of my
own packets repeated by FS-3, even when I've been iGated or completed a QSO.
However, I'm usually being bombarded by so many non-APRS packets in the
downlink on nearly a continuous basis for almost the entire pass that I
wouldn't be surprised if the D72's user interface or decoding processing
just isn't able to keep up in real time.

At the risk of introducing confusion based on my inexperience using FS-3, I
will say that I do know when using the D72 with the ISS digipeater or with
any standard simplex digipeater, when your packet is repeated you do get
realtime visual and audio indication it was repeated. The radio makes a
unique audio alert when it receives its own packets repeated back and the
screen flashes "MY POSITION" above "via RS0ISS" or whatever the callsign of
the digipeater is. This can be seen in my video below. The limitation I am
familiar with is that your repeated/received packets do not then show up in
the LIST, which can be confusing, as it was for me as seen in the below.
video. I believe the D74 does allow you to view your repeated/received
packets in its LIST.
