[amsat-bb] Help me understand my iGate?

Hi everyone.

I've been trying to improve the effectiveness of the SDR iGate that I have
listening on 145.825 and am finally seeing more packets.

Since duplicates don't show up on ariss.net, that explains why not all my
received packets show up on the website.  Just for my own education, I'll
often compare what my iGate receives from the ISS or PSAT to what shows up
on ariss.net to verify that mine are in fact duplicates.

Today on a PSAT pass I noticed that one of my received packets was a
duplicate (which is fine) but the other packet that I received was also NOT
on the website.  So, now we're not talking about a duplicate - it didn't
get accepted to the site for some other reason.

Here's the packet as I received it.  I'm guessing that the issue is that it
wasn't digipeated by a station ID of "ARISS*", but I'd like to know for
sure.  If anyone is really good with APRS in general or the APRS sat
digipeaters in particular, I sure would appreciate hearing from you.

Digipeater WIDE1 (probably PSAT) audio level = 77(8/8)   [SINGLE]
