i have 5 radios on all day with these in some of them.
it is VERY rare to hear anything.
especially voice.
the packet is automatic,, they send it up and it comes back down with ARISS attached or something like that.
there is a hookup for the audio of a radio and a program in a computer to see the TV stuff and i think the packet stuff, but i never tried it.
keep busy
