Can't digipeat APRS thru satellites
My packet setup gets digipeated instantly on terrestrial APRS networks, and works fine with ARISS, but even with overhead passes on NO-44 and NO-84, when I copy the birds well, I can't manage to get an APRS packet digipeated. Even if I crank the power up to 50 watts, using the M2 LEOpack antennas, those birds simply are deaf to me. I'm sending to CQ via ARISS, as my reading of the online docs seems to indicate that is appropriate. I've also tried CQ via PCSAT-1 and CQ via PSAT (for NO-84) but still no joy. I've also played with TX delay. Nothing works. What am I doing wrong? -- Mark D.

Mark,
If you are trying to digipeat through NO-44, you will need to use W3ADO-1 as the path. For NO-84, it won't digipeat anything sent via PSAT, but you can use ARISS or APRSAT for the path. I have not used NO-44 in a while, but when it is getting enough power from its solar panels it does work with W3ADO-1. NO-84 is actually a good APRS digipeater, even though not many stations are picked up by the Internet gateways. It is possible that the gateways that work fine with the ISS and its stronger signals just don't do as well with the weaker signals from NO-84. With my TH-D72A and Elk, I hear NO-84 well, and it seems to hear me OK once it is up a few degrees above the horizon during its passes.
Hope to see/hear you soon on NO-84. I have logged one packet QSO on that satellite, and will try for more. I also want to try the 10m/70cm PSK31 transponder, but for now my TH-D72A and Elk antenna is able to use NO-84's packet digipeater well.
Good luck, and 73!

I have exactly the same problem. I can hear NO-84 and some of the packets get out on the Igates, but I have never been able to get my own transmissions recognized by NO-84. I use 25 watts into an eggbeater and CQ via ARISS. NO-84 just ignores me, even on high angle passes. (For the record, getting into ISS is no problem for me with my set-up.)
I'd love to hear how some others get in. I suspect they are using trackable yagis.

So, apparently, NO-84 is hearing me, but I've just never received any of my own packets. My reception is hit and miss, even on high angle passes. Guess I'll go ahead and get that preamp! (My radio and my ears are both needing help hearing. This is gonna get expensive!)
Thanks for the info, Neil!

Steve,
I'm using a "trackable Elk" antenna when I work NO-84. OK, I am holding the antenna and pointing it at the satellite, twisting as needed to keep up with what the satellite is doing in orbit. As I mentioned in my earlier post, I am using a TH-D72A HT - just 5 watts. What path (UNPROTO) are you using with NO-84? PSAT doesn't work, but ARISS or APRSAT will work. I've used both of those successfully.
Remember that NO-84 transmits in the millwatt range, where ISS has many times more transmitter power for packet. I think this is also where many of the gateways are having difficulties with NO-84 - it just isn't as strong as the ISS.
73!

How are your tones? About 90% of the packets on the air are overdeviated, distorted, skewed, unbalanced, not properly emphasized or demphaasized or neither. These work "fine" terrestrially when weak signals are not involved but may be 20 dB or more away from good performance with weak signals or picky receivers. I can decode PSAT with 5 bars on the Kenwood TH-D72, but have no other experience to compare. I remember good balanced tones did 3 bars on a D700, but typical bad terrestrial signals would not decode sometimes with all 9 bars!
The ear can tell between good tones (listen to ISS) and bad tones (listen to 144.39!)
We have a bgighawatt experimental air defense radar near Wash DC on tethered balloon blasting out power at 143 and 149 mHz and all over the place. I wonder if PSAT gets overloaded by that? PSAT does not listen to carrier detect, so when it has a packet to send, it sends it.

Thanks for the many replies. I suspect that not using W3ADO-1 may be the problem.
Listening to the monitor on my IC-9100 my packets sound just fine -- I can hear no difference between the monitor and ISS downlink so far as quality and level of the tones are concerned. I've also listened on another nearby radio and the packets sound right to me. I'd like to be able to look at them on a scope, but I don't have that capability.
Hearing NO-44 is not the issue. I hear it fine. It just ignores me.

NO-44 PCSAT is usually only capable of about one good packet per pass. If the batteries can get one long 1 second packet out, then it uses up the batteries for the rest of the pass. (Very frustrating for control ops when a user hits it while we are trying to command)...

-Joe KM1P
We have chosen to use the NORAD ID 40654 as the object number for PSAT. NORAD ID 40654 is labeled as PSAT in the SpaceTrack website where we get all the rest of the our Keplerian elements for other satellites in TLE format. We have chosen to follow SpaceTrack's lead to avoid confusion in the future.
Note ... because PSAT was launched on a military rocket flight, we cannot get the TLEs directly from SpaceTrack. We can get them from the satellite owner/operator. This is how we acquire the TLEs for PSAT and BRICSat each week. But the owner/operator, in many cases, does not try to sort out who is who on a launch with multiple cubesats. The TLEs we get from the owner/operator are not labeled as BRICsat and PSAT, so we rely on our own amateur community (Nico Janssen, PA0DLO and others) to sort the list of TLEs out for us and to verify who is who.
