[amsat-bb] Mystery sat --> sat lists

[Hans BX2ABT]

Hello Pedro,

Thanks for the tip to show all sats on amsat.org.ar. I will certainly 
bookmark that on my shack PC.

I forgot about the JE9PEL list, but after consulting that I am still not 
sure what it was. The problem with doppler shift is that you are not 
sure what the base frequency of the signal is. It could be as high as 
437.505 or 437.510, who knows? It was definitely not Athenoxat-1, 
because they have a very different data burst look and timing, plus CW 
ID. I'll keep on looking, though. Who knows, maybe it's a pirate 
satellite, hi hi.

73 and good DX.
