[amsat-bb] ISS ping box

Hi Andrew

It's great to see your interest in QSOs via the ISS. 

Maybe Just let your analog computer (brain) do the sending only when you're at the keyboard so that the (limited) channel is (more) clear when you're not at the computer.

I have used Dire Wolf as a software TNC, works fine.  Test and prep your station when you're at the keyboard then disable transmission until you return.  Unattended beacons when the ground stations can't hear each other causes enough uplink contention already, so a minimalist approach makes things go well. 

Think you may find Steve and Clayton eager to enjoy a QSO with you.  

Then again, you may tell us you are thinking of doing  something beyond just getting unattended packets through the ISS ? (As Clayton also inquires). Something else you're thinking?

Most of all, have Fun !!!

Thanks,
Mike
