Hi Brad!
If you are making packet QSOs through the ISS digipeater, you can also use NO-84 when its 145.825 MHz digipeater is on. Look for the PSAT call sign on that frequency when the digipeater is on (PSAT-1 is seen when NO-84's digipeater is off).
With a Kenwood TH-D72 or TM-D710G, or possibly other radios or combinations of radios, you may be able to work the FalconSat-3 satellite. AMSAT has information specifically for that satellite at:
http://www.amsat.org/falconsat-3/
and there is a PDF file with an AMSAT Journal article I wrote on working the FalconSat-3 digipeater on the Station and Operating Hints page at the AMSAT web site:
https://www.amsat.org/station-and-operating-hints/
That article also touches on an experiment I did with a TH-D74 and an SDR receiver. A little more to manage than a single radio or piece of software, but another option for those wanting to try FalconSat-3. I have not tried to use the onboard mailbox/BBS system; just the digipeater.

I have mastered packet exchange through the ISS and would love to do packets on the APRS satellites. However, I have not found an article, etc,. that tells how to do it. I understand that it is not quite the same as the ISS/digipeaters contacts. If one can't find an "instruction sheet", how can one participate? I was hoping that this year's AMSAT satellite book would give a clue, but due to obvious circumstances, the book has not been published. Since I am the only one in my ham clubs who does any packets at all, help is not going to come from local hams. I am very thankful for the help from some hams around the US who elmered me, so far.
