[amsat-bb] NO-84 mystery solved

On the 0340 UTC pass, I again could see someone in the passband, but it
showed as 10 traces rather than one.  At the end of the transmission, I
heard a CW ID.  So I emailed the operator.  

Turns out, he's transmitting PropNet PSK beacon signal, and it's falling in
the passband of NO-84 uplink!  Now it makes sense.  And of course I could
not decode his PSK31 signal, because it's sending data aligned with the
PropNet algorithm!

I still can't see my signal on the downlink.  Maybe I need to try a
different antenna..
