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!

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.
