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.

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.
