[amsat-bb] ISS ping box

Thu Sep 22 18:41:20 UTC 2016

I'll generally send a CQ, then wait for three or four packets to be
received to see if anyone is answering. If I don't see any answers in
three to four received packets, I'll send another CQ. I've never timed
it, but I'm guessing that it's more than once a minute. 

So, it's fairly frequent, but I'm sitting there paying attention and in
control of when my packets go out. If I don't get any replies after four
or five CQs during the peak of the pass, I'll quit sending to make room
for other folks. 

Just my opinion, but I don't feel like the frequency of sending is as
important as the concept of being attentive to and in control of your
transmissions. Transmit, then listen/watch for a reply. Repeat as
appropriate for conditions (amount of traffic) and your station's (and
the Space Station's) capabilities. 

Personally, I don't see a reason for an unattended beacon transmission
to the ISS. Probably some folks have come up with a reason. If so,
please share.
